Title: Liquid fuel combustion device
Inventor: YAMAMOTO KATSUHIKO
IPC: F23D11/34
Filed: 1978-02-01
Abstract: PURPOSE: To stabilize the atomizing characteristics by circulating liquid fuel, which is atomized by the ultrasonic vibrator to be combusted in the combusting part, between the tank and the container with the ultrasonic vibrator.  
     CONSTITUTION: When electricity is supplied to the electric blower 19 and the pump 7, the liquid fuel in the tank 1 is supplied to the contaner 8 by the pump 7, and then, when the level of the liquid fuel in  the container 8 and the outer cylinder 24 connected with the container 8 rises to a certain level, the fuel falls into the tank 1 through the hole 27 of the control pipe 26 and the return pipe 25. Then the float 30 goes up to turn the switch 29 'on' to supply electricity to the oscillator 13, and the fountain shaped liquid colum 15 is formed on the surface of the liquid by the ultrasonic vibrator 10 to atomize the fuel. The excessive liquid fuel which is not atomized is returned back to the tank 1 through the return pipe 25, and the atomizing characteristics by the vibrator 10 can be stalized.

Title: Device for reproducing pcm digital audio signal
Inventor: HASEGAWA TSUNAO
IPC: H03M1/08
Filed: 1991-01-31
Abstract: PURPOSE:To obtain natural reproduced sounds by generating the high-frequency component of 20kHz which is lost at the time of recording and adding the generated component to original signals. CONSTITUTION:PCM digital audio signals which are read out from a recording medium and have a sampling frequency fs are first supplied to an LPF 1 by which the component of the signals having frequencies higher than the frequency fs/2 of the digital audio signals is cut off and the signals passed through the LPF 1 have a sampling frequency of 4fs. When the sampling frequency is raised to 4fs in such way, a harmonic component of a frequency range from the fs/2 to 2fs can be generated. When the digital audio signals having the sampling frequency 4fs outputted from the LPF 1 are supplied to a multiplier 2, second- order harmonic components are generated and, when the second-order harmonic components are supplied to another multiplier 3, third-order harmonic components are generated. The signals added by an adder 6 are added to the signals from the LPF 1 by means of an adder 8 after passing through an HPF 7 and have a harmonic component.

Title: Checking method of electrophotographic sensitive body
Inventor: ARAI AKIO
IPC: G03G21/00
Filed: 1983-01-25
Abstract: PURPOSE:To detect easily and accurately abnormaity of a photosensitive layer by deciding on abnormality of a measured potential at some point by comparing it with the mean value of measured values at several points right before it when scanning on the entire surface of a photosensitive body and measuring the surface potential. CONSTITUTION:A corona impressed voltage corresponding to a specific electrification potential is obtained before the primary measurement, and the high-voltage power source of an electrifier 2 is controlled automatically to make electrification constant. While the photosensitive body 1 is rotated, a probe 3 for potential detection is scanned from one end to the other to measure the surface potential. In this case, surface-potential data 5-10 at precedent points are stored invariably and their mean value is calculated and compared with the current measured value to obtain variation. When the difference between the mean value and measured value exceeds a specific reference value, a decision on a abnormal part is made. If the measured value at a point A is judged to be abnormal by this method, variation levels on (x) and (y) coordinates are recorded and the number of defects and their positions are displayed lastly. Thus, the abnormality detection is performed easily and accurately.

Abstract: PURPOSE:To recognize the same correct data as a sender by providing a code generating circuit to convert a data signal to a pulse train and verifying the kind of substituted data. CONSTITUTION:Parallel data is fetched from the external and held in a data register 1. Content of the register 1 is sent to a >>0]/>>1] deciding circuit 6 in accordance with the timing of a timing circuit 2. The circuit 6 starts a >>0] code generating circuit 7 or a >>1] code generating circuit 8 according as one inputted data is '0' or '1'. Circuits 7 and 8 convert data to pulse trains, which consist of three or more pulses having the same width, different in width and send them to a gate driver 10. The pulse width of the output of the driver 0 is detected and counted by a '0' or '1' code checking circuit, and the data signal is recognized as '0' or '1' when the corresponding counted value exceeds a prescribed value. Thus, since pulses having the normal width are always checked, the kind of the pulse train is detected to recognize the same correct data as the sender.

Filed: 1994-02-04
Abstract: PURPOSE:To make a circuit small by mounting high frequency integrated circuit part chips onto a dielectric substrate as flip chips and to prevent a high frequency characteristic from being lost due to small reactive component. CONSTITUTION:An RF IC pair chip 19 is mounted and inductors L16, L17, Lo, for an Lo signal input matching circuit 16 and an RF signal input matching circuit 17, and drain inductors L11, L12 of an RF amplifier are formed on a dielectric substrate 20 by spiral inductors.

Title: Resin sealing die for semiconductor device
Inventor: HAMADA KATSUHIRO
IPC: B29C45/02
Filed: 1992-01-28
Abstract: PURPOSE:To acquire a die of high effective utilization factor of resin by making an outer periphery of a pot whereto slid thermosetting resin is cast constitute a part of a cavity which forms a resin package of a product. CONSTITUTION:After solid resin 9 is cast on a plunger 10 inside a pot part 6 with a die opened, two lead frames 11 are arranged on a bottom force 1 of the die. Then, the die is closed and the lead frames 11 are held between. When a specified pressure is applied, a plunger 10 rises at the same time and injects resin 9 from the pot 6 to an inside of the cavity 8 directly. In the process, the resin 9 melts due to heat of the die and gels. The plunger 10 stops rising just as the resin 9 fills all the corners of the cavity 8 and a specified pressure is applied. It continues to hold a pressure until the resin package 12 is formed after the resin is cured by heat from the die. Thereby, it is possible to eliminate the need for a runner part for making molten resin flow into a cavity.
