Title: Error information memory
Inventor: SATOU HIROSHI
IPC: G06F11/07
Filed: 1983-06-28
Abstract: PURPOSE:To fetch only the real error information and to improve the reliability of an error information memory by discriminating whether the transmitted error information is due to the electric power supply break of a device to be connected. CONSTITUTION:The error information sent from a device 101 to be connected is stored to a memory circuit 102 having the same sequence between input and output. A data memory control circuit 103 detects that the error information is stored to the circuit 102 and therefore reads the error information out of the circuit 102 to transmit it to a data comparator 104. The circuit 104 discriminates whether the error information is due to the power supply break of the device 101. Based on the result of said discrimination, a data memory circuit 106 fetches and stores only the real error information excepting for artificial faults due to the power supply break.

Abstract: PURPOSE:To obtain desired data by simple operation by monitoring the output of measurement of electric power in each feeder, and inverting the sum of the other sound electric powers when abnormality occurs in one output. CONSTITUTION:Electric powers which are transmitted through feeders 11 - 1n and 21 - 2n that are connected to a common bus line 1 are measured at power converters 121 - 12n and 221 - 22n.

Title: Simultaneous operation inhibiting circuit for output buffer
Inventor: UEDA KATSU
IPC: H03K19/0175
Filed: 1992-05-11
Abstract: PURPOSE:To inhibit a simultaneous operation of the buffer by less hardware without necessitating independently the hardware for each of object output signals by utilizing an enable function of the output buffer for inhibiting the simultaneous operation. CONSTITUTION:By using an enable signal of the output buffer, output buffers are grounded by a unit by which a simultaneous operation does not become a problem, that is, grouped into output buffer groups 10-30, the enable signal of the output buffer of the respective groups is divided in one clock, and the simultaneous operation is inhibited. This is, since data processed in the inside of an LSI is synchronized with a clock signal CLK from a sequence circuit such as an FF, etc., provided in the inside of the LSI, a simultaneous operation waveform synchronized with the clock signal CLK such as a waveform of an input signal DATA1 is outputted. That is, when a input signal DATA0 is outputted through the output buffer as it is, the buffer is operated simultaneously, and it causes a malfunction of the LSI. Accordingly, at a variation point of the signal DATA0, each enable signal EN1-EN3 is all set to '0' to make the buffer operation impossible.

Abstract: PURPOSE:To adapt a transfer material separating device to an image forming device by distorting a bias applied to an electrostatic separating discharger so that crest values nearby the positive and negative peak values are decreased, and specifying the frequency of a rectangular alternating current. CONSTITUTION:When a transfer material reaches a separation position where the electrostatic separating discharger 3 is provided, the separating discharger 3 applied a voltage generated by superposing voltages from a rectangular wave AC power source 4 and a variable DC power source 5 for controlling the difference current between the positive and negative components of a discharging current to discharge the transfer material electrostatically, which is separated from an image carrier. At this time, the rectangular wave is used as the applied alternating current for the image forming device which uses an amorphous silicon photosensitive body and performs electrostatic separation and its frequency is set to 250 to 1,000Hz, preferably, 400 to 600Hz. Abnormal discharge is therefore evaded and the deterioration and damage of the photosensitive body due to the abnormal discharge and further an image defect are prevented to perform the separation excellently.

IPC: H04B1/10
Filed: 1995-05-16
Abstract: PURPOSE: To vary a noise detection sensitivity based on the modulation rate and to prevent the aural change of a noise reduction effect. CONSTITUTION: The modulation rate of the radio wave source is defeated by an FM detection circuit 4 via an LPF 10, and the value of this detected modulation rate is converted into the value of the DC voltage through a 2nd level detection circuit 11.

In such a constitution, the detection gains of a conventional multipath noise reduction device can be controlled in response to the modulation rate of the radio wave source.

Title: Method and device for stray light removal for raman spectral diffusion
Inventor: EGUCHI KINYA
IPC: G01N21/65
Filed: 1988-05-16
Abstract: PURPOSE:To perform laser Raman spectral diffusion with high reliability by guiding light which is emitted by a sample to a spectrometer through a dichroic mirror which reflects exciting laser light regularly and transmits Raman scattered light. CONSTITUTION:Laser reflected light 3 and Raman scattered light 4 generated by the sample 2 which is irradiated with exciting laser light 1 become parallel light beams through a lens 5 and are made incident on dichroic mirrors 6, 7, 8, and 9 arranged at specific angles to incident light one after another. Incident laser reflected light 3 is reflected according to the characteristics of the mirrors 6, 7, 8, and 9, but the Raman scattered light 4, on the other hand, is reflected by none of the mirrors 6 to 9 and transmitted to travel backward through the same optical path with the incident light, so that the light enters a spectrometer 11 through a condenser lens 10. Thus, a decrease in the quantity of the Raman scattered light is reduced to remove stray light caused by the laser reflected light, thereby performing the high-reliability laser Raman spectral diffusion.

Title: Forming method of multilayer interconnection
Inventor: TAKAO SEIJI
IPC: H01L21/31
Filed: 1984-06-08
Abstract: PURPOSE:To prevent the generation of the accident of disconnection at a stepped section even in a fine multilayer interconnection by forming an Si nitride film onto a lower layer film, to which an Si oxide film is shaped through a sputtering method, through a plasma CVD method and forming an inter-layer insulating film. CONSTITUTION:A sputtering oxide film 204 is formed to a semiconductor substrate 201, to which an electrode wiring layer 203 is shaped, to a desired form. A plasma nitride film 205 is shaped onto the film 204. It is preferable that the thickness of the film 204 extends over 0.1-1.0mum and the thickness of the Si nitride film over 0.5-2.0mum. Since the oxide film is shaped through a sputtering method according to the manufacture, the oxide film excellently creeps and can be attached uniformly, and a foundation insulating film having a preferable positive slope form can be shaped. The film 205 is grown on the film 204 having said form. According to a plasma CVD method, the step coverage of the nitride film is improved, and the nitride film can be stuck precisely onto a slope. Accordingly, since the film 205 is formed gently, the next second layer electrode wiring 206 is also shaped smoothly, and there is no possibility of disconnection.

Title: Fire self-alarming system
Inventor: KONOO HIDEYUKI
IPC: G08B17/00
Filed: 1994-05-31
Abstract: PURPOSE:To improve the operation efficiency by detecting an address overlap of sensors with the addresses. CONSTITUTION:As for plural response signals outputted when the addresses of the sensors with the address overlap, when all the sensors with the addresses output bit signals of LOW level almost at the same time, the signals are received as LOW-level signals; when the bit signal of at least one sensor is an HIGH level, it is inputted to a signal reception part 9 which receives it as the HIGH level to obtain one received signal. A comparison part 16 compares the check code, found by arithmetic based upon the serial number included in the received signal, with the check code included in the received signal and a data processing part 17 decides that the address overlap judging from the difference between those check codes. Consequently, the address overlap of the sensors with the address can be detected.
