Title: Bicycle headlamp
Inventor: HASHIMOTO TSUTOMU
IPC: B62J6/02
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a bicycle headlamp capable of exhibiting the individualities of a rider and a bicycle even in the night and useful for traffic safety by providing a strip colored transparent part on a lens to partially form a strip colored light in lighting. SOLUTION: A colored transparent part 5 is provided so as to cross the center of a colorless transparent lens 4 in a proper width. The colored transparent part may be formed integrally with the colorless transparent lens 4, but it can be formed separately from the lens 4. Namely, a desired colored transparent part 5 can be formed by integrally laying a U-shaped sectional colored transparent material 5a of yellow, blue or pink having insert pieces 6 having proper width and length which are integrally formed on both sides thereof along the reverse side of the lens 4. When a lamp 3 is lighted, the light transmitted through the colored transparent part 5 in the center part is changed to a colored light, so that the difference from a bicycle using a conventional illuminating lamp can be recognized by those around it.  Further, since the presence of a oncoming vehicle can be quickly recognized in night traveling, this headlamp can contribute to traffic safety.

Abstract: PURPOSE:To obtain an ultrasonic sealing technique which reduces the padding of a circumference which is easy to occur in sealing to a little, eliminates the upward curvature of a flip, and forms a patern equivalent to a head seal pattern with regard to design, by employing ultrasonic sealing for the sealing of the flap. CONSTITUTION:The sticking part of a jacket is formed by ultrasonic sealing in a belt-like pattern which is equivalent to the seal pattern of a heat seal on the market with regard to design. The belt-like pattern is 0.5-6mm. width and 5-190mm. length and a texture pattern which is employed by the heat seal may be employed as the internal pattern of the belt-like pattern. The tip end part of an ultrasonic horn is 2mm. (W1) width and 18mm. length, and a sheet pressure part 15 is 3mm. width and 18mm. length and 0.3mm. shorter than the tip part. When the difference D in height between the sheet pressure part and tip part decreases below 0.1mm., a trace is left at the flap part around a seal part and when the difference increases above 0.4mm., padding becomes larger.

Title: Fault detection system for integrated circuit
Inventor: SARUYAMA SHUICHI
IPC: G06F11/22
Filed: 1986-09-18
Abstract: PURPOSE:To improve a fault detection rate by detecting whether or not signal values of external output terminals of all fault circuits are different from the signal value of a normal circuit and deciding that fault circuits whose signal values are different from the signal value of the normal circuit can be detected as faults. CONSTITUTION:A characteristics initial value indicating 0 or 1 is assigned by a characteristic value assigning means 4 to output values of respective storage elements whose output signal values can not be determined under the influence of a fault. Then a fault detecting and deciding means 6 decides that the combination of the characteristic initial value assigned by the means 4 and an output value when an integrated circuit is normal and the combination of the characteristic initial value and an output value 1 when the integrated circuit is normal are detected at an external output terminal. Then either of the two combinations which are observed at the external output terminal is considered to be caused under the influence of the fault to detect the fault of the integrated circuit, so the high fault detection rate can be obtained.

At the time of use, the display case 2 is moved downward toward the front of the device body by an arm supporting mechanism 3 and is put into a second operation state that the display surface faces the front by turning of the display case 2 inside out while the display case 2 moves upward from the first operation state that the display surface faces upward and, therefore, the device body may be made into the vertical type shape of nearly the same size at the time of use and at the time of housing. The loading area may be made smaller than the horizontal placement type and the sufficient working space on the loading surface 8 may be assured.

Abstract: PURPOSE: To form a container itself and upper and lower seals in a neat shape with a simple structure by lowering an arm member by interlocking motion with a pressing head to bring a pair of pressing plates in a facing direction to press both sides of the container filled with liquid and by pressing a top of the container by a pressing head. CONSTITUTION: The forming apparatus includes a conveyor 100 comprising numerous support plates 101 standing at a predetermined distance to have a container 10 filled with liquid interposed between adjacent support plates 101. The conveyor 100 is placed to pass through a pair of pressing plates 201, 201 of an upper and lower seal forming mechanism 200. When the container 10 reaches between the pressing plates 201, an arm member 203 lowers via a coupling member due to rotation of an eccentric cam, whereby the pair of pressing plates 201 are brought close to a facing direction via a cam member. Thus both sides of the container 10 are pressed, while a top of the container 10 is pressed by a pressing head 202 to form the container 10 in a predetermined shape.

Title: Slot antenna
Inventor: HARA YASUHIKO
IPC: H01Q13/10
Filed: 1983-11-24
Abstract: PURPOSE:To obtain a slot antenna having the satisfactory matching over a wide band range by increasing the width of a slot connected to a microstrip line and providing a conductor line within the slot and in parallel to this slot. CONSTITUTION:A conductor 2 is bonded to a single side of a dielectric substrate 1, and a slot 3 of width W is formed to the conductor surface 2 with a conductor 5 of width (b) left inside the surface 2. A feed microstrip line 4 is provided with deflection toward the position of the length (t) from the center of the slot 3 so that the line 4 is matched with the slot 3. The increase of the W increases the band of a slot antenna. While the conductor 5 suppresses the generation of reactance component at discontinuous points of both sides of the slot 3 as the width W increases. At the same time, the slot characteristics having a large width can be maintained equivalently owing to a pull-in phenomenon of the mutual impedance.

IPC: G11B20/14
Filed: 1990-08-23
Abstract: PURPOSE:To make it unnecessary to use an exclusive measuring instrument, to shorten a measuring time and to improve the reliability of this data recording/reproducing device by providing the device with an window shifting means for shifting a window signal by the control of a control means and separating read data pulse string into data pulses and clock pulses based upon the shifted window signal. CONSTITUTION:A controller 27 sets up the window shifting variable of the window shifting circuit 29 to a maximum value on the advance or delay side. In addition, the controller 27 shifts the shifting variable to the delay or advance side in each fixed value, converts the strobe offset of the window signal and checks whether data can be accurately read out or not in each conversion to detect a limit point EARLY or LATE on the advance side or the delay side capable of accurately reading out data. The controller 27 finds out a reading margin from a difference between both the limit points EARLY, LATE. Since the reading margin can be automatically measured without using a measuring instrument to be exclusively used for the reading margin, the measuring time can be shortened and the reliability of the device can be improved.
