Title: Tuning fork type bending crystal oscillator
Inventor: KAWASHIMA HIROFUMI
IPC: H03H9/215
Filed: 1981-09-29
Abstract: PURPOSE:To use the titled oscillator for a clinical thermometer, by selecting a cut angle optimally and improving sensitivity of frequency to temperature. CONSTITUTION:When a tuning fork type bending crystal oscillator made of a Z plate is rotated by theta deg. by using an X axis as a rotary shaft, then a frequency sensitivity alpha is increased as the theta is increased, and a cut angle theta with =-20ppm/ deg.C is about 25 deg. and the alpha is made maximum between 50 and 60 deg. of theta. As the cut angle increases further, the alpha is decreased and the alpha is made minimum at about 90 deg. of theta, and when the cut angle is further increased, the alpha is again increased and the alpha is made maximum at around 120 deg.. When the cut angle is further increased, the absolute value of the alpha is decreased and the cut angle where the alpha is -20ppm/ deg.C attains about 165 deg.. Thus, practically, the cut angle ranges between 25 and 165 deg..

Title: Semiconductor optical modulator
Inventor: ISHIMURA EITARO
IPC: G02F1/015
Filed: 1993-06-25
Abstract: PURPOSE:To reduce the absorption loss of the semiconductor optical modulator at the time of a no-bias voltage. CONSTITUTION:The light absorption layer of a multi-quantum well uses a material which is different in band discontinuity quantity of a barrier layer 2 and well layers 10a and 10b for quantum well layers 10a and 10b which adjoin to each other across the barrier layer 2, and light is modulated by using the electric field dependence of an absorption coefficient between the adjacent quantum wells. The absorption peak at the time of electric field impression greatly shifts to a long wavelength side and the absorption peak wavelength in the absence of an electric field and the absorption peak wavelength (modulation wavelength) in the presence of the electric field are greatly different, so the absorption loss in the absence of the electric field is reduced.

Title: Manufacture of earthquake sensitive tripping device of earth leakage breaker
Inventor: SUGIURA ATSUO
IPC: H02H5/00
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To break and open a cable way by sending a signal of a pseudo- leakage generator to an existing circuit breaker by sensing an earthquake by a seismograph when it reaches a certain seismic intensity after an earthquake occurs. SOLUTION: A pseudo-leakage generator 2 is connected to an electric contact point of a seismograph 1, and a leakage current is made to flow to an existing earth leakage breaker 3. Here, it is connected between a power source side neutral point and a load side charging line so that the leakage current is automatically broken when the existing earth leakage breaker 3 operates. When the seismograph 1 operates by an earthquake, since a pseudo-leakage current flows to the earth leakage breaker 3, the existing earth leakage breaker 3 is tripped, and a cable way is broken. Therefore, a fire caused by a collapsed house and an electric equipment such as a damaged and overturned electric appliance can be prevented.

Title: Photometric circuit
Inventor: NAKAI MASAAKI
IPC: G01J1/44
Filed: 1979-11-28
Abstract: PURPOSE:To avoid the occurrence of the ringing with the junction capacity and then realize a quick reset of the photodiode to the normal state, by discharging once excessively the charged electric charge of the junction capacity of the photodiode and then giving the charging again later. CONSTITUTION:With supply of the noise signal from outside, the output of the operational amplifier OA1 has a high potential. Then the junction capacity of the photodiode PD is charged to turn the output potential of the OA1 to zero, and the output of the comparator OA2 becomes high potential. Thus the capacitor C1 is charged quickly via the transistors Q1 and Q2. As a result, the current of the Q3 increases, and the charged electric charge of the junction capacity of the PD is discharged gradually by the output current of the PD and the current of the Q3. In this case, the negative input potential of the OA1 is set lower than the positive potential, and thus the charged electric charge of the PD is discharged once and excessively. Then the charging is carried out again to the junction capacity of the PD via the D1 when the current of the Q3 becomes zero, thus obtaining the normal state.

Filed: 1988-06-23
Abstract: PURPOSE:To improve durability and drop-out performance by specifying the content of nitrogen atom in a diamond-like hard carbon film of the recording medium in which the carbon film is provided on a ferromagnetic metal film. CONSTITUTION:On a polymer film 4, a fine particle coating layer 5 incorporated with Al2O3, Zn O, etc., and the ferromagnetic metal film 6 consisting of Co-O, Co-Os, etc., are formed by high frequency sputtering. Then, the diamond-like hard carbon film 7 contg. 5 - 15 atomic % nitrogen atoms, and successively a lubricating layer 8 consisting of perfluorecarbonic acid are formed to consti tute the recording medium. If the content of nitrogen atom in the film 7 is <=5 atomic %, dropout may increase and still-durability may be deteriorated. On the other hand, if the content of nitrogen exceeds 15 atomic %, hardness and durability are lowered. Thereby, by specifying the content, the recording medium has good durability and drop-out property.

Title: Roping method for wiring
Inventor: JINGUJI YOSHIO
IPC: B61B12/02
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To safely and surely perform a work for pulling up tools by paying out a messanger rope in an opposite direction, allowing an elastic body to fall by gravity to the ground and roping a prescribed wiring in a reverse U-turn shape. SOLUTION: An elastic body is capable of moving without having a possibility of being entangled because a messanger rope and an auxiliary rope 10 move in the direction of the arrow 12 in a state that tension states are kept if the messanger rope is pulled back and the auxiliary rope 10 is paid out in the direction of the arrow 12 at the same speed. When the elastic body reaches a prescribed location, the elastic body falls by gravity in the direction of the arrow 13 if the pulling back of the messanger rope is discontinued, the messanger rope is paid out in the opposite direction and only the auxiliary rope 10 is paid out in the direction of the arrow 12. Therefore, the elastic body falls in a stable state and is suspended in a reverse U-turn shape if the auxiliary rope 10 is paid out at proper speed.

Title: Vacuum pump device
Inventor: KOMURA FUMIO

Filed: 1987-06-24
Abstract: PURPOSE:To reduce pressure fluctuation caused in an oil seal by forming a base plate between an pump casing and the oil seal with a communicating passage to connect a working chamber to the oil seal, and providing an opening part toward the oil seal outside from a through hole of the base plate. CONSTITUTION:A communicating passage 26, which makes a working chamber 12 engaging in a suction stroke communicate with the interior of an oil seal 21, is composed of the grooves 23, 24 and a communicating port 25 of a base plate 6. Negative pressure in the working chamber 12 acts into the communicating passage 26 to draw oil having flowed in an oil seal 7 into the working chamber 12 for its removing. In addition to that, since the end of the groove 23 on the side of a through hole 8 separates outside from the inner periphery of the through hole 8, the opening rate of the communicating passage 26 decreases to make it difficult for the oil to flow in the oil seal. Thus pressure fluctuation caused in the oil seal can be reduced.
