Title: Powdery deodorizer composite
Inventor: MORIGUCHI HIROSHI
IPC: C08L3/00
Filed: 1990-11-16
Abstract: PURPOSE:To obtain the deodorizer composite which continues a deodorization effect extending over a long period by mixing the prescribed quantity of rice starch and glutaric aldehyde. CONSTITUTION:The powdery deodorizer composite is obtained by mixing rice starch and glutaric aldehyde. As for its mixing ratio, with respect to 100 weight part rice starch, 3-60 weight part glutaric aldehyde is suitable. The rice starch becomes a carrier at the time when a deodorizer of a liquid is powdery, starts to cause gradually a melting reaction under the existence of water, that is, when it comes into contact with moisture, and continues a melting phenomenon extending over a long period. The glutaric aldehyde is a liquid having a suppression effect for a nitrogen compound bad smell (ammonia, amine, etc.), a sulphur compound bad smell (hydrogen sulfide, mercaptan, etc.). It is confirmed that a stable deodorizing function is displayed even if this composite is used together with starch, etc. In this invention, this composite is absorbed and sucked to rice starch powder, and eluted by moisture, and its deodorization effect is displayed.

Title: Radio communication system
Inventor: SUZUKI TOSHIRO
IPC: H04J4/00
Filed: 1993-12-10
Abstract: PURPOSE:To stably continue communication without receiving interference from another radio system by dividing frame time longer than carrier sense time into short sub frame times. CONSTITUTION:Data for communication are transmitted in a transmission cycle Tf by using sub frames for communication so as to be transmitted in the cycle shorter than carrier sense time Ts and to insist on the state under use to the other radio equipment. Concerning sub frames excepting for the sub frames for communication, a pilot signal (priority assert signal) is transmitted by a pilot signal transmitting means. Namely, a BS 1 transmits the communication data in the first slot of the first sub frame and transmits the pilot signal of the even number sub frame after the second sub frame. In the odd number sub frame after the third sub frame, the BS 1 stops the transmission so that the remaining BS can transmit the communication data. Thus, when the transmission is once started, stable communication service can be provided without being disturbed by the other radio equipment.

Title: Optical recording and reproducing device
Inventor: EBINA KOICHI
IPC: G11B7/09
Filed: 1990-11-16
Abstract: PURPOSE:To correct a deviation associated with the environmental variation and secular change so as to stabilize an optical recording and reproducing device by realizing such a constitution that can correct the deviation generated in an operating mechanism and deviations generated in a control means and signal generating means under a using condition after adjustment at the time of manufacture. CONSTITUTION:When a correcting operation starting time recognizing means 1 issues a correcting operation request signal 102 based on an elapsed time signal 101 generated by an elapsed time recognizing means 9, a controlled variable correcting state is set. Then an operating mechanism driving amount controlling means 2 stops operations and generates a controlled variable signal so as to move an operating mechanism to its reference position. Therefore, the displaced amount of the mechanism 10 is inputted to a signal comparing means 8, compared with a reference signal 103 for correction, and stored in a deviation recognizing means 3 as a correcting amount recognizing signal 105. When the signal 102 is stopped and an ordinary operating state is set, the means 3 issues a deviation signal 106 by combining the stored deviated amount and the deviation in the ordinary operation state. When such constitution is used, this optical recording and reproducing device can make stable operations, because deviations can be corrected even when the deviations occur in the mechanism 10, means 2, and a drive signal generation circuit 4.

Title: Transmitter
Inventor: INAMURA HIROYUKI
IPC: H04L1/00
Filed: 1986-12-25
Abstract: PURPOSE:To extract lots of information from an inhibited pattern by calculating n-set of m-bit pattern code strings through the inverse conversion from a signal of n-pattern being the conversion of 1-bit so as to extract a common data when a code string converted from m-bit into n-bit is an inhibited pattern. CONSTITUTION:A converter 1 converts a 5-bit data into a 6-bit data in response to the prescribed rule and a transmission circuit 3 converts it into a serial data and sends the result. If an error takes place during transmission and 6-bit data extracted by a reception circuit 5 is an inhibited pattern, since 1-bit error is caused easily and 6-data subjected to one bit conversion is calculated and converted into 5-bit data by the inverse conversion table. The data common to all among the data whose conversion is finished is generated as an extracted code string data. Thus, even if the inhibited pattern is received, much information is extracted from the inhibited pattern and the effect of the error is decreased.

Title: Signal processing circuit of solid-state image pickup device
Inventor: ASAIDA TAKASHI
IPC: H04N9/09
Filed: 1989-11-30
Abstract: PURPOSE:To satisfactorily execute the image enhancement processing by selecting a detail signal generating means and an interpolating means to a characteristic in which even/odd number of the number of pieces of zero points of each digital filter coincide with each other. CONSTITUTION:In the case even/odd numbers of degrees (m), (n) of each digital filter of interpolation processing parts 13R, 13G and 13B and a detail signal generating part 11 do not coincide with each other, a group delay by the digital filter for an interpolation processing in the interpolation processing parts 13R, 13G and 13B, and a group delay by the digital filter for a differential processing for generating a detail signal in the detail signal generating part 11 are shifted from each other, and an image enhancement processing cannot be executed satisfactorily. Accordingly, by allowing the even/odd numbers of the degrees (m), (n) of each digital filter to coincide with each other, the group delay by the digital filter for the interpolation processing and the group delay by the digital filter for the differential processing for generating the detail signal are allowed to coincide with each other. In such a way, even if the detail signal is added to the signal whose interpolation processing is ended, the image enhancement processing can be executed satisfactorily.

Title: Automatic diff-lock device of vehicle
Inventor: IWAMOTO MASATOSHI
IPC: F16H48/38
Filed: 1990-11-15
Abstract: PURPOSE:To lock/unlock a diff-lock device automatically by locking a hydraulic type diff-lock device when a vehicle makes a straight run, providing a changeover valve which changes over the hydraulic type diff-lock device to the unlock side when the vehicle makes a turn, and utilizing the pressure difference within a hydraulic steering device. CONSTITUTION:When a vehicle is making a straight run, the pressures in the right and the left chambers of the hydraulic cylinder 10 of a steering device 9 are equalized to each other and a changeover valve 24 is set in a neutral and locked position. The pressure oil which is fed from a hydraulic pump 23 to a return side circuit 25 through the steering device 9 is fed to hydraulic cylinders 15, 16 of diff-lock devices 11, 12 through the changeover valve 24. Thus, diff-lock shifters 13, 14 slide and lock diff devices 4, 6 to be inoperative in differential action. On the other hand, when a vehicle makes a turn, a steering wheel 19 is steered to the left hand side, for example, the control valve 20 and the pump 21 of the steering device 9 make differential motion, and the pressure oil from the hydraulic pump 23 is fed to the chamber 10a of the hydraulic cylinder 10. This generates a large pressure difference between respective right and the left chamber spaces of the hydraulic cylinder 10, leading to the changeover of the changeover valve 24 to the unlock side.

Abstract: PURPOSE: To provide a rectifier diode which has improved diode characteristics (reverse voltage, forward voltage, backward recovery time, peak inverse voltage, soft recovery, etc.). CONSTITUTION: A silicon rectifier diode has such a srtructure that rectifier PN junctions which are made by forming a plurality P regions (3-1 to 3-3) of P-type conductivity which have a depth Xp from the surface of a high resistance 'i' layer 2 of N-type conductivity and Schottky barrier junctions are alternately arranged and a high resistance 'i' layer 2 of a thickness Wi in the depth direction is located adjacent to the P regions (3-1 to 3-3) and a low resistance N+ layer 1 is located adjacent to the high resistance 'i' layer 2.
