Inventor: YUI TSUTOMU
IPC: H04N19/91
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To prevent malfunctions and mis-diagnosis by informing a receiver side of coding accuracy with respect to the method for information accuracy of image coding and the image coder. SOLUTION: A transmission section 4 sends coding information which denotes a fact of coding an original image into an intra-coding image (I picture) that is the result of in-frame coding, an inter-frame forward prediction coding image (P picture) that is the result of inter-frame forward coding, and a two-way prediction coding image (B picture) that is the result of inter-frame 2-way coding by an image coding processing section 1. A coding information discriminating circuit section 3 compares an image which results from decoding and reproducing at least either of the P and B pictures by an image decoding processing section 2 including an inverse quantization section 22, an inverse DCT arithmetic section 23, and a prediction memory section 24 or the like with the original image which corresponds to the reproduced image to obtain the coding accuracy.

Title: Connection method of architectural member
Inventor: IKEGAMI NORIAKI
IPC: C09J175/04
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To impart connection and heat-insulation functions to an architectural member by airtightly applying a one-component type moisture-setting adhesive to a connection position of mutual wooden architectural members such as wall members and making the adhesive foam and cure after the wooden architectural members have been connected to each other. SOLUTION: Since a urethane adhesive reacts with water and hardens and further expands with foaming, the adhesive fills the space between architectural members and enhances the airtightness. Since the urethane adhesive is of one- component type, it is easily usable and prevents inferior adhesion or inferior foaming resulting from inferior mixing. Further, foaming expansion caused by curing reaction of the urethane adhesive becomes visible after about 30 min after application. As the foaming expansion finishes in about 24 hr, it does not give any influence to the adhesive strength or the airtightness by scraping out the adhesive on connecting the members and hence, the curing time to the completion is relatively shortened. In this way, a heating efficiency can be increased when particularly applied to a house in a cold district.

Title: Multistation transmission system
Inventor: SOGABE YASUSHI
IPC: H04L1/06
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To maintain communication quality when a conventional receiver is used by allowing a base station to perform continuous transmission by transmitting the same information burst plural times by using its own transmitter and to perform transmission by changing transmission timing from each station in every burst. SOLUTION: Base stations 1 and 2 transmit the same information to a mobile station 4 while changing transmission timing in every burst. A receiver 3 mounted on the station 4 receives the same information simultaneously transmitted from the stations 1 and 2. In this multistation transmission system performing continuous transmission in which the same information is transmitted plural times by using plural transmitter, delay quantity in each burst is changed by changing transmission timing from each station in each burst, a mobile station can perform stable communication at a position where it stops even if the mobile station stops moving by making the phase relationship between plural transmission signals random, and a circuit configuration also becomes simple because an adaptive equalizer and plural receivers are not needed any longer.

IPC: H01L21/822
Filed: 1992-12-21
Abstract: PURPOSE:To obtain a semiconductor circuit having an electrostatic breakdown preventive layer capable of surely preventing electrostatic breakdown without increasing an occupied area. CONSTITUTION:An electrostatic breakdown preventing layer 3 composed of a resistor or a resistor and a diode is formed in the lower region of an electrode pad 4 of a semiconductor circuit.

The energy due to an excess voltage applied to the electrode pad 4 does not directly flow into the inner circuit 9, but surely passes the electrostatic breakdown preventing layer 3, by which the current flowing into the inner circuit 9 is decreased.

CONSTITUTION:The toner can be attached on the place of the photosensitive body 11 whose surface potential V1 is V1>-600, for example. Then, the significant width S of the photosensitive body, that means, the width size of the photosensitive body 11 within a range that it can be stably electrostatically charged by an electrostatic charger and the effective width E of electrostatic charge, that means, the width size of the electrostatic charge range on the photosensitive body 11 which is electrostatically charged by the electrostatic charger are formed to be longer than the length of the developing roller, that means, the whole length of the developing roller 14a and the sealing parts 14b thereof are faced to the area of the effective width E of the electrostatic charge (V1=-900). Thus, even when the toner is leaked from the sealing parts 14b at the time of developing, it is prevented from being electrostatically attached on the photosensitive body 11.

Abstract: PROBLEM TO BE SOLVED: To prevent performance of a motor from deteriorating, by performing correction for the temperature characteristics of an oscillator so that an oscillation frequency from the oscillator for outputting an arbitrary oscillation frequency according to an input signal level can be constantly maintained within a drive frequency band of the motor. SOLUTION: When a motor 10 starts to be driven, a voltage corresponding to a drive signal with a frequency that is fully higher than the audible sound generation band of the ultrasonic motor 10 is supplied from a power feed terminal 32 to the input terminal of an oscillator 42. Then, the ultrasonic motor 10 is driven due to oscillation at an oscillation frequency according to the voltage. After that, a voltage that is supplied from the power feed terminal 32 to the oscillator 42 is changed so that the frequency of the drive signal can be reduced into a drive frequency band that is slightly higher than the audible sound generation band, and the drive frequency is maintained within the drive frequency band of the ultrasonic motor 10.  When temperature is increased, the electrical resistance of a thermally sensitive resistor 38 increases, and the input voltage of the oscillator 42 decreases for correction by the amount of the shifting of the oscillation frequency.
