Title: Reclining seat
Inventor: YAMAGUCHI MASAKI
IPC: A47C1/024
Filed: 1989-10-31
Abstract: PURPOSE:To do arbitrary angular adjustment of a receiving seat by providing a movable plate mounted on either a seat cushion or a seat back, an ultrasonic vibrator mounted on the other one, and a pressure attaching mechanism for pressure attaching the vibrator to the movable plate. CONSTITUTION:When a piezo-electric element 109 is impressed for vibration with alternative voltage of a frequency decided by the shape and size of an elastic member 108, the member 108 oscillates in flexure vibration second mode and stationary wave is excited. At this time, friction force between a driving part 111a and 111b and a movable plate 105 rapidly decreases due to the vibration of an ultrasonic vibrator 107. Thus the angle of a seat back 104 can be changed between arbitrary ones with minimum force. If the impression of alternative voltage on the piezo-electric element 109 is stopped, the seat back 104 is held by the attachment of a supporting member 104.

IPC: H04B1/7073
Filed: 1993-11-12
Abstract: PURPOSE:To obtain a spread spectrum signal decoder capable of accurately detecting the edge timing of demodulated data. CONSTITUTION:An exclusive-OR circuit 4 and a digital carrier generator 5 eliminate a carrier component from a received signal that is a spread spectrum signal. A C/A code generator 6 generates a C/A code as a prescribed periodic signal. A digital correlator 7 inputs the received signal from which the carrier component is eliminated by the exclusive-OR circuit 4, and the C/A code by the C/A code generator 6, and measures the correlation values of both signals sequentially at every measuring time in which a C/A code period is bisected. A controller 8 sets the correlation value in the measuring time other than that equivalent to a C/A code phase out of a set of correlation values by the digital correlator 7 as the correlation value including a data component in a section of time of 1msec. Also, the controller 8 detects the edge timing of the demodulated data based on the correlation value.

Filed: 1989-10-31
Abstract: PURPOSE:To attain stable motor control by generating plural pulse signals at the timing of the rise and fall of an output from a frequency generation signal detection means and generating a frequency generation signal based on the pulse signal. CONSTITUTION:A frequency generation FG sensor 12 detects the number of revolution in a motor 11 and the detection signal is shaped into a digital signal in a waveform shaping circuit 13.

A vibrator 22 obtains the inverse signal B2 of the signal A from an invertor 26, generates the pulse signal D and outputs it to the OR circuit 24. The circuit 24 takes the OR of signals C and D and outputs a signal E being the result to a motor control system as the FG signal. Thus, the frequency of the FG signal is set high and stable motor control is attained.

Filed: 1985-12-16
Abstract: PURPOSE:To obtain a film of high quality with a very small number of crystal defects, by evaporating germanium on a silicon surface, and making the surface layer be a mixed crystal layer of silicon and germanium, and then vaporizing the mixed crystal to etch the silicon surface. CONSTITUTION:When a protective oxidizing film 21 on a surface is removed and then four or more atomic layers of germanium are laminated with a substrate temperature kept at 200 deg.C or more, the surface layer becomes a mixed crystal layer 40 of silicon and germanium. The mixed crystal layer 40 vaporizes with the substrate temperature being 900 deg.C or more, resultantly etching of the substrate surface layer being completed. Thus, very clean surface can be obtained, because contaminants such as carbon reserving on the surface are removed from the surface.

Filed: 1990-10-22
Abstract: PURPOSE:To enable the electrical connection under the high temperature condition by making a coefficient of thermal expansion of a conductive particle of the aeolotropic conductive film larger than a coefficient of thermal expansion of thermoplastic resin or thermosetting resin. CONSTITUTION:Aeolotropic conductive film 5 is located along the arrangement direction of electrode terminals 3 arranged on a first electrode substrate 1, and the aeolotropic conductive film 5 consists of the thermoplastic resin 6 and the conductive particles 7 distributed in the thermoplastic resin 6. A coefficient of thermal expansion of the conductive particles 7 is set larger than a coefficient of thermal expansion of the thermoplastic resin 6.

Abstract: PURPOSE:To fix a full-color and both-side image without generating irregularities in an image by providing an elastic surface whose impact resilience is equal to or below a specific ratio on a pair of fixing rotors respectively. CONSTITUTION:A fixing roller 1 is formed having a core metal 5 made of aluminum as an outer layer and which is covered with additional silicone rubber 6 by a prescribed thickness. A pressure roller 2 is installed under the fixing roller 1, and the pressure roller 2 is formed having the core metal 7 made of aluminum as the outer layer and which is covered with additional silicone rubber 9 by a prescribed thickness.

But, in the case that the impact resilience is too low, the rollers are drastically deformed in a short time, then, uneven gloss occurs on the image owing to the deformation of the surfaces of the rollers, and also, a recording material is not stably carried. Meanwhile, in the case that the impact resilience is too high, the irregularities in the image are generated.
