Title: Manufacture of semiconductor device
Inventor: UEDA NAOTO
IPC: H01L21/301
Filed: 1990-11-26
Abstract: PURPOSE:To eliminate the previous expanding process for picking up a dice by forming a V-shaped groove which has the prescribed angle at the cut of the dice and permitting the shape of the sucking collet leading edge of the dice to have an angle which is wider than the angle of the V-shaped groove formed on the dice by the prescribed angle. CONSTITUTION:The angle theta' of the triangle blade of a triangle blade-shaped leading edge sucking collet 8 and the angle theta of a V-shaped kerf 9 are permitted to be theta'>theta. A very small space 10 is made between a desired dice 2 and the vicinal dice 2 by pressing the triangle blade-shaped leading edge vacuum collet 8 into the V-shaped kerf 9. Then, the desired dice 2 is sucked and the suction collet 8 is ascended to pick up the dice. Thus, expanding process is not necessitated before picking up the dice, and the desired dice is picked up without damaging the vicinal dice.

Title: Oscilloscope apparatus for electric power
Inventor: TSUNODA TAKANORI
IPC: G01R13/20
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To obtain an oscilloscope apparatus by which the life of a contact maker at a breaker can be managed by extracting, when the breaker is operated on the basis of current waveform data at the generation of an accident, the magnitude of an arc current flowing to the contact maker and estimating the wear amount of a main contact maker. SOLUTION: A CPU 1 reads out, from an A/D converter 11, digital data on signals sampled by sample-and-hold circuits 9a to 9h, inputs an operating contact 52TX at a protective relay from a contact signal input port 14, and stores, in a RAM 3, waveform data on voltages and currents for a definite period before and after a breaker is operated. After that, an arc current value at every phase is extracted as the magnitude of an arc current on the basis of a stored current waveform, the wear amount of a contact maker is computed on the basis of the value of the arc current so as to be accumulated, and it is judged whether the value exceeds 70% of a predetermined life amount or not. When the value exceeds 70% of the life amount, an alarm contact signal is output via a contact-signal output part 13.

Title: Voice transmitter
Inventor: IWATA SHINICHIRO
IPC: G10L19/00
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a voice transmitter in which voice reproduction is not interrupted during transmission of voice data in real time while minimizing deterioration in sound quality without remarkable increase of a transmission speed of a communication path with respect to a baud rate of digital voice data. SOLUTION: An ADPCM encoder 2 converts a received analog voice signal into an ADPCM digital voice code. An S/P conversion part 3 converts a serial signal into a parallel signal in the unit of bytes. A code conversion section 4 detects it when a code being a subject of escape is included in the ADPCM data of the units of bytes, increases/decreases digital voice data by one and converts the result into a code being not a subject of escape, respectively. A transmission FIFO memory 5 stores sequentially ADPCM data. A P/S conversion section 11 converts the parallel data in the unit of bytes into a serial signal. A transmission section 12 sends the serial data to an opposite device as an infrared ray.

Title: Printer and its control method
Inventor: ARIGA KAZUHISA
IPC: B41J29/20
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To make it easy to confirm how much consumables of the printer have been consumed and how much components have been wron away by storing the history frequency of operation of the printer in the printer. SOLUTION: A process control part 10 when controlling a mechanism 16 by a mechanism control part 15 stores its operation frequency in a RAM 14. The operation frequency of the mechanism 16 stored in the RAM 14 is stored in a flash ROM 13 in specific timing. At this time, the operation time of the printer measured by the timer of the process control part 10 is also stored together. The flash ROM 13 is readable and writable by the process control part 10 and holds its contents even when no electric power is supplied. The operation frequency of the printer stored in the flash ROM 13 is copied to the RAM 14 first and the subsequent operation frequency is counted by updating the contents of the RAM 14. Consequently, the operation frequency of the printer can be counted continuously without reference to whether the power source is ON or OFF.

Title: Traffic signal
Inventor: KANO CHIYUKI
IPC: G08G1/095
Filed: 1991-10-07
Abstract: PURPOSE:To use inexpensive LEDs(light emitting diodes) to change the color tone and to raise the luminance by constituting a traffic signal of LED groups which emit light different in colors and causing them to emit light with different duty ratios. CONSTITUTION:LEDs for red light emission, those for green light emission, and those for blue light emission are alternately arranged on concentric circles on the surface of an LED attaching substrate.

Title: Fluorescent character display tube
Inventor: KENTSU KOJI
IPC: H01J31/15
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To prevent generation of abnormal noise in a frame when a pulse signal is applied to a wire in a fluorescent character display tube having a cathode supporting body frame mounted onto a base board provided with wires for an anode and a control electrode. SOLUTION: A wire 3 on a base board 2 is arranged so as not to be arranged in areas 6, 6 in both ends of the base board 2, and a frame 5 serving as a cathode supporting body is arranged in the area 6 free of the wire 3. No wire 3 is arranged below the frame 5. The frame 5 is not brought into contact with the wire 3. Measurement of resonance based on forcible impression of a pulse to a wire for an anode or the like is carried out in various kinds of fluorescent character display tubes, and consequently, it is proved that abnormal noise is greatly caused in a fluorescent character display tube in which a frame 5 is overlapped with a wire 3 or brought into contact with the wire 3.  It seems that abnormal noise is generated because the frame 5 resonates when it is influenced by a change in the electric field, as an electric field around the wire 3 is changed by a pulse signal given to the wire 3 if the wire 3 and the frame 5 are close to each other. In the previously mentioned structure, no unusual noise is generated.

Next, at the next divisional point n+1. of the winding 10, similarly the position (xn+1, y) in the plane 6n+1 is calculated so as to coincide the plane 6n+1 with the plane, in which the feed eye locates by rotating the cylindrical mandrel by the angular difference (thetan+1-thetan) and shifting the feed eye to the position (xn+1, y) in order to perform the winding operation of the fiber.

Title: Production of self-support
Inventor: CLAAR TERRY D
IPC: C04B35/65
Filed: 1988-12-23
Abstract: This invention relates generally to a novel method of manufacturing a composite body. More particularly, the present invention relates to a method for modifying the resultant properties of a composite body, by, for example, minimizing the amount of porosity present in the composite body. Additives such as TaG, ZrC, ZrB2, VC, NbC, WC, W2B5 and/or MoO2B5 can be combined with a boron carbide material (2) which is thereafter reactively infiltrated by a parent metal (3). The composite body comprises one or more boron-containing compounds (e.g., a boride or a boride and a carbide) which is made by the reactive infiltration of molten parent metal (3) into the boron carbide mass (2). Particular emphasis is placed upon modifying the properties of a ZrB2-ZrC-Zr composite body. However, the methods disclosed in the application are believed to be generic to a number of parent metals and preform materials.
