Patent JP-H03284870-A (JP)
Title: Package for high-frequency integrated circuit
Inventor: YOSHII YASUSHI
IPC: H01L21/66
Filed: 1990-03-30
Abstract: PURPOSE:To prevent short-circuit caused by mis-contact of bias probe needles and facilitate measurement by arranging second bias terminals, which are connected to first bias terminals in a package, at side ends different from the side ends of the package. CONSTITUTION:Two shoulders 12 are newly made at the outer sides of both side plates 2b approximately perpendicular to both side plates 2a on which shoulders 3 having I/O terminals 4 and bias supply terminals 4a are made. Bias supply terminals 13 on the upper faces of the shoulders 12 are connected to the bias supply terminals 4a on the shoulders 3 with microstrip lines 14 in the space formed by the side plates 2a and 2b. Bias supply probe needles 7 are brought into contact with the bias supply terminals 13, not with the bias supply terminals 4a. The terminals 13 are made on the side plates 2b perpendicular to the side plates 2a having the I/O terminals 4, therefore, even if the bias supply probe needles 7 are brought into contact with bias supply terminals 13, the needles are free from mis-contact with conductor plates 10 and the other bias supply terminals 13.

Title: Mobile radio communication system
Inventor: TAKEI HIROSHI
IPC: H04B5/00
Filed: 1986-04-15
Abstract: PURPOSE:To secure continuous call without interruption on the border between a closed space and an opened space by connecting an antenna turning to the opened space to the end of a leakage coaxial cable in the closed space. CONSTITUTION:A transmission high frequency signal is supplied from a private base station to the leakage coaxial cable 3 laid in a tunnel 2 from the right direction in the figure. Since the antenna 4 is connected and matched to/with the terminal of the cable 3, the transmission high frequency signal at the terminal of the cable 3 is efficiently radiated to the opened space. When a moving body mounting a radiotelephone set is located on a position 1a in the tunnel 2 to be the closed space, call is executed through the cable 3. When the moving body is moved and reached to the position 1b on the outlet of the tunnel 2, the electric field of radio waves radiated from the cable 3 is suddenly attenuated, but a sufficient electric field is obtained through the antenna 4 connected to the end of the cable 3.

Title: Hand brake retaining apparatus
Inventor: FUNAKOSHI TAKESHI
IPC: B60T7/10
Filed: 1978-07-14
Abstract: PURPOSE: To prevent uncontrollable running by releasing the tightening of a brake through a triple grip control with the engagement of a pin and a groove while a grip is loosely fitted into a rod.  
     CONSTITUTION: As a rod 11 is pushed up to the end of a tube, a pin of the rod is driven by the tube, and a pin 18 relatively moves in the direction a. With the charge of a spring 16, the pin 18 runs over an upslope H, returning into a ring groove 19. To relex the tightening, following a push, a grip 14 must be turned until it stops in the direction opposite to releasing and then, inverted in the direction of releasing. Accordingly, only application of any external force on the grip 14 won't release the brake.

Title: Optical rotation detector
Inventor: GOTOU YASUHIRO
IPC: G01D5/347
Filed: 1982-05-21
Abstract: PURPOSE:To enable the detection of information on motor rotation by obtaining two sets each of reverse phase signals with the rotation of a rotary plate from two photoelectric conversion means comprising photoelectric conversion elements separated radially over the entire periphery and electrodes for electrically connecting the elements. CONSTITUTION:Light from a flat light source 13 is shielded with a rotary plate 14 while irradiating a first photoelectric conversion element 19b and 19a alternately through a first slit 17a of the rotary plate 14 and hence, it is allowed to irradiate the conversion elements 19a and 19b in the opposite phase to each other. This light is applied to an arithmetic amplifier and a photoelectro-motive current-voltage conversion circuit to obtain voltages Va and Vb in the elements 19a and 19b in proportion to the quantity of irradiated light. The voltages Va and Vb are opposite in the phase. When these voltages are applied to a differential amplification circuit, they cancel noises of the same phase as those to increase signals thereby producing signals with a high signal-noise ratio. This enables accurate detection of information on the motor rotation.

IPC: H01L39/22
Filed: 1990-03-31
Abstract: PURPOSE:To eliminate formation of a Schottky barrier and to perform the operation of a transistor by interposing a metal thin layer made of metal having high wettability with oxide superconductor, a metal thin layer and an alloy layer made of alloy of a material for forming at least a collector between a base and the collector.

Since the layer 7 is made of Bi having high wettability with BSCCO for forming the region 4, a junction with the region 4 is excellent, conducted by osmosis of superconductor energy gap due to a superconducting proximity effect, its potential change is reduced to almost eliminate reflection of quasi-particles from the superconductor. Accordingly, a junction between a base and a collector becomes a junction between metal and alloy, a Schottky barrier is not formed, the quasi-particles flow from the base to the collector, thereby performing the operation of a transistor.

Inventor: ITO AKIHIKO
IPC: G02F1/133
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of uneven brightness even in the case of a display with movement by applying a selected voltage in time dispersion for one frame period to each scanning electrode, or applying it in time centralization for one frame period. SOLUTION: In the case of displaying a still picture, a selected voltage is applied to each scanning electrode Y1-Ym in time dispersion for one frame period by a scanning electrode driving circuit 120, and in the case of displaying a moving picture, the voltage is applied to the electrodes in time centralization for one frame period. According to this driving method, unselected period becomes short in the case of the still picture display, therefore, on-display picture elements are decreased in the variation of brightness, and the contrast is prevented from being decreased. On the other hand, in the case of the moving picture display, the selected voltage is applied in time centralization for one frame period, therefore, any picture element uniformly varies in the brightness for the unselected period, therefore, what is called unevenness of luminance can be suppressed.
