Patent JP-H03103736-A (JP)
Title: Torque measuring instrument
Inventor: HANAZAWA AKIYOSHI
IPC: G01L3/10
Filed: 1989-09-18
Abstract: PURPOSE:To easily adjust the zero point by detecting a circuit output voltage and then applying an offset voltage so that the output voltage indicates the zero point even if the zero point drifts owing to the used history of a sensor part, etc. CONSTITUTION:When the zero point drifts owing to the used history of the sensor part, etc., an output 25 appears although no torque operates on a shaft 1 and is monitored by a resistance 22. Then, a differential amplifier 27 generates an output corresponding to a monitoring signal from the resistance and a difference from a reference voltage source 26 and the output is sent to a D/A converter 30 through the A/D converter 29 of a sample-hold circuit 28. The converter 30 does not normally output the signal from the converter 29 immediately and sends a signal based upon the internal data to an offset adder 19 through a buffer 31. When, however, an operator confirms that torque operating on the shaft 1 is zero and operates the manual switch 33 of a reset circuit 32 to send a reset signal to the converter 30, the converter 30 sends an output corresponding to the converter 29 to send the offset voltage indicating that the output is zero to an adding circuit.

Title: Thermal transfer material
Inventor: ASAOKA MASANOBU
IPC: B41M5/382
Filed: 1986-10-15
Abstract: PURPOSE:To print with high density and favorable sharpness even on a recording material poor in surface smoothnes, by a construction wherein heat-fusible materials in a thermally transferrable ink layer constitute at least two kinds of domains, and at least one kind of the domains are constituted of colored heat-fusible resin particulates. CONSTITUTION:A thermal transfer material 1 comprises a thermally transferrable ink layer 3 comprising a heat-fusible materials, on a sheet-shaped base 2. The ink layer 3 has at least one kind each of domains constituted respectively of colored heat-fusible resin particulates A and a non-granular phase B. A plastic film having a relatively favorable heat resistance, cellophane or a parchment paper, a condenser paper or the like can be suitably used as the base 2. The thickness of the base is preferably about 1-15mum where a thermal head is expected to be used as a heat source. Since a large difference in cohesive force is generated between a heated part and a non-heated part in the thermally transferrable ink layer, a clear recorded image can be obtained, and since a latent image of the record produces an adhesive force for adhesion to a recording material imagewise, favorable printing can be achieved even on a recording material poor in surface smoothness.

Title: Receiver
Inventor: YOSHIKAWA YOSHISHIGE
IPC: H04B1/26
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a receiver which can suitably incorporate an IC by inputting and delaying a high frequency signal to be received, adding the delay output to the high frequency signal, converting the addition output into an intermediate frequency signal and inputting the conversion output to a demodulation circuit. SOLUTION: The signal inputted to a high frequency signal input terminal 1 is inputted to a 1st delay means 2 whose delay time is set at 5 μ sec. The output of the means 2 is added to the signal inputted to the terminal 1 via an addition circuit 3. Under such conditions, both components of frequency 100 kHz and 300 kHz are canceled with each other since the phase is shifted by 180 deg. between the output signals of the means 2 and the input signal of the terminal 1. Thus, the output of the circuit 3 is set at zero. Meanwhile, the components of frequency OHz, 200 kHz and 400 kHz are strengthened with each other and the output of the circuit 3 is increased. An image elimination filter 10 consists of simple circuit elements such as the means 2 and the circuit 3 and accordingly its circuit is significantly simplified.

Title: Autopiano
Inventor: INABA TATSUYA
IPC: G10F1/22
Filed: 1993-09-29
Abstract: PURPOSE:To provide an autopiano which can prevent its playing sound from reaching the periphery by stopping a string strike sound and generating the playing sound through only an electronic sound source. CONSTITUTION:A solenoid 10 drives a key 11 on the basis of musical sound data stored on a floppy disk. Once the key 11 is driven, a hammer shank 21 is pushed up by a jack 17 to reaches the position shown by the broken line in the figure through inertial motion, thereby abutting on cushion felt 37. A hammer 23 after starting the inertial motion is stopped from moving, so no string strike sound is generated, but the operation of the key 11 is the same as ever. The operation of the key 11, on the other hand, is detected by a stepped shutter 61 and key sensors 63 and 65 and sent as MIDI information to an electronic musical instrument. The electronic musical instrument, therefore, outputs the playing sound.

Title: Wrapping film
Inventor: OIKAWA YUKINORI
IPC: B65D75/28
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To unify the kinds of multiwrapping films and perform a large variety of multiwrappings with one kind of multiwrapping film, by providing all necessary matters onto a single-item wrapping film, and covering matters unnecessary for multiwrapping with the shield part of the multiwrapping film. SOLUTION: In addition to a single-item barcode 12, a multibarcode 16 is disposed on the right upper corner of the transparent part 13 of the rear of a single-item wrapping film 11. The multiwrapping film 15 displays only matters required for multiwrapping except the single-item barcode 12, by making the part excepting a barcode shield part 18 transparent. This prevents the single- item barcode 12 from being read accidentally and makes it possible to read surely the multibarcode 16. Further, because the multiwrapping film 15 is provided with only the shield part 18, film kinds can be unified into one irrespective of the number of items to be wrapped together.

Title: Mask
Inventor: SUGISHIMA KENJI
IPC: G03F1/22
Filed: 1986-10-14
Abstract: PURPOSE:To reduce the deformation of a mask in the vertical deirection by a method wherein a protruded part and a recessed part are formed in the thickness direction at the exposure region of a second absorbing layer, for X-ray lithography or the like, whose mask frame is thick so that the stress of the second absorbing layer can be relaxed at the protruded and recessed parts. CONSTITUTION:A first absorbing, patterned and thin layer 2 is formed at a rectangular exposure region on a membrane 1 of a mask, and a second absorbing layer 3 with a thick frame part is formed at its outer circumference. A protruded part 3A and a recessed part 3B are formed at the frame part on the exposure region of the absorbing layer 3. If the recessed part 3B is arranged face to face with the protruded part 3A and the protruded part 3A is arranged face to face with the recessed part 3B at the inner circumference of the second absorbing layer 3 of the mask where the protruded and recessed parts are formed, the stress at the exposure region can be relaxed even when the thickness of the frame part is thin. As a result, the deformation in the vertical direction during the patterning process for the manufacture of the mask can be reduced, and the change in the position and size of a pattern can be suppressed with a view to preventing the out-of-focus phenomenon at the exposure.

IPC: F25D11/00
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To prevent the decrease of quantity of ice formed in the periphery of a pipe located in the vicinity of the uppermost step of an evaporating pipe. SOLUTION: In a water tank 20 for storing cooling water, a spirally wound drink pipe 30 in which a drink passes and a spirally wound evaporating pipe 40 in which a refrigerant passes to cool cooling water are coaxially provided. Ice detecting sensors S1 and S2 are arranged between the drink pipe 30 and the evaporating pipe 40. When both the ice detecting sensors S1 and S2 are exposed in the cooling water, a compressor starts a refrigerating operation. When either of them is covered with ice, the compressor stops the refrigerating operation. Further, the compressor is continuously operated irrespective of the detected results of the ice detecting sensors S1 and S2, until the lapse of prescribed time after the operation of the compressor is started.  Thus, a refrigerant having a cooling capacity is supplied throughout the evaporating pipe 40 to prevent the quantity of ice from decreasing in the periphery of the upper part of the evaporating pipe 40.

Title: Optical fiber coupler and production thereof
Inventor: SASAKI HIROYUKI
IPC: G02B6/28
Filed: 1989-09-20
Abstract: PURPOSE:To obtain the optical fiber coupler having the long wavelength period of the degree of coupling by fusing and stretching the stretched parts formed by stretching >=2 pieces of optical fibers having the propagation constant equal to each other respectively at an equal degree of stretching to each other. CONSTITUTION:The optical fiber 1a having a core 2a and a clad 3a and the optical fiber 1b having a core 2b and a clad 3b are previously stretched by the same length by using a heating means to form the stretched parts 5a, 5b. For example, the respective optical fibers 1a, 1b each having 10mum core diameter are respectively stretched by about 10mm. The stretched parts 5a, 5b of the stretched optical fibers 1a, 2b are intersected with each other or are aligned in parallel and the aligned parts thereof and the parts near the same are fused by using the heating means. The fused parts and the parts near the same are stretched by using the heating means, by which the fused and stretched part 6 is obtd. Since the fiber diameters is reduced in the stretched parts 5a, 5b in this way, the coupling at a small wavelength is possible and the length of the wavelength period of the degree of coupling is increased.

Title: Electromagnetic actuator for driving shutter
Inventor: TANAKA YOSHINOBU
IPC: G03B9/24
Filed: 1987-09-30
Abstract: PURPOSE:To miniaturize a device and to reduce the consumption of a feeding power by functioning the leakage flux of an electromagnetic coil effectively with the function of the magnetic pole of a core leg, and increasing a shutter driving force at the time of opening a shutter by displacing a permanent magnet from a first position to a second position. CONSTITUTION:A device is constituted in such a way that the electromagnetic coil 39 is equipped by reducing a distance from the tip plane of a second core leg, and also, the permanent magnet 23 is displaced in the direction of the second core leg confronting with a first core leg at the time of performing the feeding of an electromagnet 37, and it is displaced in a direction opposite to the above case by stopping the feeding. In other words, the leakage flux of the electromagnetic coil functions effectively in addition to the magnetic function of a core magnetic pole, and the displacement operation of the permanent magnet can be accelerated remarkably. Since the leakage flux of the electromagnetic coil is utilized effectively in such way, it is possible to obtain the shutter driving force whose operating speed is accelerated without using a core with high quality or increasing the cross-section of the core to evade magnetic saturation. In such a way, it is possible to miniaturize the constitution of the device, and to obtain an electromagnetic actuator with low cost and with low power consumption.
