Title: Liquid phase epitaxial growing method
Inventor: KAWABATA TOSHIHARU
IPC: C30B19/00
Filed: 1980-04-16
Abstract: PURPOSE: To grow a high quality epitaxial layer having a uniform crystal composition with a simple apparatus by growing an epitaxial layer on a substrate of a single crystalline semiconductur by a concn. gradient due to the difference between solvent and solute in specific gravity and simultaneously melting the semiconductor.  
     CONSTITUTION: Substrate 1 of single crystalline GaP for growing an epitaxial layer is set on the top of boat 3, and plate 7 of polycrystalline GaP on the bottom of boat 3. Polycrystalline GaP as a solute is added to Ga as a solvent and heated to a predetermined temp. to form satd, melt 2. Melt 2 is introduced into boat 3, and melt 2, substrate 1 and plate 7 are kept at a predetermined temp. Since the solute GaP is lower than the solvent Ga in specific gravity, it moves upward to cause supersaturation in the upper part of melt 2. Accordingly, an epitaxial layer is grown on substrate 1 set at the upper part. On the other hand, the lower part becomes an unsatd. state, so GaP 7 is melted, moves upward, and grows on substrate 1 to give a fine epitaxial layer with high productivity.

Title: Display element driving device
Inventor: MIYADERA SHUNICHI
IPC: H04N5/66
Filed: 1991-02-22
Abstract: PURPOSE:To compensate the drop-out of a chrominance signal also in addition to a luminance signal. CONSTITUTION:During the detection period of a drop-out in an RF video signal (RF luminance signal) by a drop-out detector, a gate driver 11 turns off a thin film transistor(TR) 25 on a display part corresponding to the RF video signal so as to interrupt the supply of a video signal (original chrominance signal) to a corresponding capacitor 26. Consequently the video signal (original chrominance signal) stored in the capacitor 26 is not updated and the video signal one field stored in the capacitor 26 is displayed.

Title: Photographic film processing device
Inventor: KAJI TOSHIKAZU
IPC: G03D15/00
Filed: 1995-03-10
Abstract: PURPOSE: To improve the durability of a magnetic head. CONSTITUTION: A sliding member 71 having the radius of curvature larger than that of the magnetic head 70 is arranged near the upstream side of the head 70, and dirt and dust adhere to the member 71 by rubbing as negative film 14 is carried. The reason why the contact surface of the sliding member with the negative film 14 is set larger than the radius of curvature of the head 70 is because a condition associated with the contact (sliding) of the negative film 14 with the head 70 and the member 71 is made the same and above that.  Namely, the dirt and the dust adhering to the head 70 are surely allowed to adhere to the member 71 in the case they have the same circular-arc surface, and the unit contact area of the member 71 with the negative film 14 is made larger in the case the radius of curvature of the member 71 is set larger than that of the head 70, whereby the removal of the dirt and the dust are not missed.

Title: Graphic data compressing method
Inventor: SHIBUYA SHOZO
IPC: G06T3/00
Filed: 1989-03-02
Abstract: PURPOSE:To prohibit the withdrawal of a coast line that exists in original chart data to a land side when, for example, the chart data is compressed, by making an approximate straight line pass through a non-prohibited side overhang against an original boundary, when the data compression of the boundary comprising of plural points is performed. CONSTITUTION:The approximate straight line is found by thinning the point comprising the boundary, and the almost parallel displacement of the approximate straight line to the non-prohibited overhang side against the boundary is performed when the approximate straight line is positioned at the overhang prohibited side against the boundary, and the intersections of plural almost parallel-displaced approximate straight lines are set as new data. For example, the approximate straight lines passing the points 1, 6, 9... are extracted by an approximate straight line extraction processing, and the parallel displacement of, for example, the approximate straight line 1-6 is performed as shown in 1'-6' and also, the approximate straight line 6-9 as shown in 6'-9' to a sea side, respectively by a parallel displacement processing for the approximate straight line, and the intersection 6', etc., of those approximate straight lines is generated as the new data. Thereby, the chart data in which no approximate straight line passes the land side in the original chart and compressed data is generated.

Title: Constant high q voltage controlled oscillator and its generating method
Inventor: MAIKERU MATSUKUGIN
IPC: H03B5/12
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To maintain a constant Q in a voltage controlled oscillator(VCO) tuned over a wide frequency band. SOLUTION: A tank circuit 111 sets a center frequency of an oscillator circuit 112. A variable reactance circuit 113 provides a variable valid reactance equivalent to a tuning voltage 117 applied to tune the VCO to both ends of the tank circuit 111. A resistive current from the variable reactance circuit is rectified by a rectifier circuit 120. A comparator generates a Q control voltage corresponding to a reference current Iref at a terminal 126. The control voltage is applied to the variable resistance circuit 122 to supply a differential resistive current to cancel the resistive current from the variable reactance circuit to keep a constant Q in the VCO.

Title: Radio relay system in mobile object
Inventor: TANIGUCHI HISAO
IPC: H04B7/26
Filed: 1993-03-12
Abstract: PURPOSE:To surely send information from a mobile object to a stationary station even at a location having lots of obstacles by providing a reflector in which a transmission wave with a strong directivity sent from the mobile object is sent to the stationary station by using a reflecting plate whose angle is made variable with a location of the mobile body. CONSTITUTION:A radio wave sent from a mobile object 1 is reflected by reflectors 3-5 with driver and stationary reflecting plates 6, 7 and fed to a stationary station 2 by detouring obstacle A. A position and a progressing direction of the mobile object 1 are measured by a position measurement device such as a GPS, and since the change is at first measured by a drive mechanism of the mobile object 1, the antenna azimuth angle and elevating angle with respect to the reflector 3 are calculated by a CPU of the mobile object 1 itself and outputted to the driver. Since it is located in the entirely opposite direction when viewing from the reflector 3, the data are received to calculate a direction of the reflecting plate of the reflector 3 and the result is outputted to the driver. Thus, the mobile object 1 is traced smoothly and the transmission from the mobile object 1 is ensured.

Title: Biological production of hydrogen and its apparatus
IPC: C12P3/00
Filed: 1992-03-11
Abstract: PURPOSE:To improve the production efficiency of H2 by dissolving a gas containing CO2 in an organic liquid, then separating and taking out the H2 in a gas formed by decomposing organic substances with anaerobic bacteria and simultaneously dissolving the residual gas in the organic liquid. CONSTITUTION:An organic liquid (A) such as a waste liquor is introduced into a CO2 dissolving vessel 1, passed through an introduction pipe 7 and introduced into an H2 producing reactor 2. CO2 is jetted from a return line 5 into the CO2 dissolving vessel 1 and dissolved in the organic liquid (A). H2 and CO2 are produced from organic substances in the organic liquid (A) in the H2 producing reactor 2 with anaerobic bacteria. Most of the H2 and a part of the CO2 are formed as gas bubbles, floated and collected in a vapor-phase part 10. The resultant gas bubbles are then sucked, passed through a gas discharge line 11 and fed into a gas separating means 3. The H2 is passed through a separation membrane 13 and recovered. The CO2 is passed through the return line 5 and returned to the CO2 dissolving vessel 1. In the H2 producing reactor 2, the H2 producing reaction is readily advanced due to the reduction in the total pressure caused by forced suction of the produced gas and/or reduction in H2 partial pressure caused by an increase in the CO2/H2 ratio. Thereby, the production efficiency of H2 is improved.
