Title: Method of etching aluminum foil for electrolytic capacitor
Inventor: KAZUHARA MANABU
IPC: H01G9/04
Filed: 1989-09-12
Abstract: PURPOSE:To obtain a high diffusion surface magnification and to improve mechanical strength by a method wherein, before performance of main etching, a preliminary etching is conducted and the natural oxidation film on the surface of aluminum foil is removed to the extent that its resistance will be neglected. CONSTITUTION:A preliminary etching is conducted on a sheet of aluminum foil in a first electrolytic vessel 1, and then a main etching is conducted in a second electrolytic vessel 2 by dipping the aluminum foil therein. In this case, the current density of the preliminary etching is made higher than the current density of the main etching. Also, it is desirable that the period of the preliminary etching is set at 1 to 8 seconds. A pair of electrode plates 1a and 1b are arranged in the first electrolytic vessel 1, in which the preliminary etching is conducted, so as to pinch the aluminum foil A, and an AC power source 3 is connected to the vessel 1. Also, three electrode plates 2a to 2c are arranged in the second electrolytic vessel 2, in which the main etching is conducted, in order to pinch the aluminum foil A, and two AC power sources 4a and 4b, which are in synchronous relation, are prepared.

Title: Method and device for producing control program of optical reader
Inventor: NAITO YOICHI
IPC: G06F9/06
Filed: 1988-09-22
Abstract: PURPOSE:To improve the production efficiency of a control program by using the available data as they are on a source program of the describing language and producing the data short in a screen interactive system in terms of the trial and error. CONSTITUTION:The control program which is newly produced and corrected with use of a source program of a form overlay describing language that is read to an optical reader 117 via a communication circuit, a scanner, etc., used as the reading means is outputted to a memory medium like a floppy disk 13, a magnetic tape 15, etc., set into an external memory 114. Otherwise the control program is outputted to a control program form 5 via a printer 115 or transferred to a host computer 7 which controls an optical reader 6 via a communication equipment 116 or directly to the device 6. Thus the produced control program is read into the device 6 in an off-line or on-line way. Then the device 6 reads the forms under the control of the control program and then carries out the necessary processes. Thus the read data 8 are outputted. In such a way, the production efficiency is improved for the control program.

Title: Semiconductor manufacturing equipment, manufacture of semiconductor device and recording media
Inventor: NAKAJIMA YOSHIHIRO
IPC: H01L23/29
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To appropriately maintain the quantity of flow of resin and protect the chip surface and inner leads in semiconductor manufacturing equipment for applying a liquid resin to semiconductor packages. SOLUTION: Parts 3a and 3b of a lead of a package are coated with a liquid resin 6a having a smaller filler particle size than the gap between the leads by a dispenser 5a. After the coating operation, a semiconductor chip 1 is coated with a liquid resin 6b having larger filler particle size than the gap between the leads by a dispenser 5b. Since the liquid resin 6a exhibits a lower viscosity and a higher flowability than the liquid resin 6b, desired resin is flowed out to the rear side of an insulating film 2 passing through a device hole 4 and a desired thickness of coating can be performed on the semiconductor chip 1.

Title: Attenuation device
Inventor: TAKAYAMA TAKEYUKI
IPC: G06F7/52
Filed: 1985-10-24
Abstract: PURPOSE:To obtain a circuit with extremely simple constitution by incorporating a digital filter, and also to execute attenuation with an abundant number of steps. CONSTITUTION:With respect to a data which is delayed by a shift register 1, an impulse response coefficient which is written in a coefficient ROM 2 is multiplied successively. Successively, by an accumulator 4, the data which is multiplied is added and outputted. By repeating said operation by shifting an input data, filtering is executed to a digital signal. When executing an attenuation, SWs 7-10 are all switched to the opposite side. As a result, the data which is inputted to a digital filter is multiplied by an attenuation coefficient which has been stored in a register 5, by a multiplier 3, and thereafter, inputted to a shift register 1. By repeating such an operation, an output of the digital filter is attenuated.

Title: Paper detection apparatus
Inventor: NISHIYAMA HARUO
IPC: G03G15/00
Filed: 1983-12-17
Abstract: PURPOSE:To accurately perform detection and to prevent erroneous detection caused by instantaneously generated noise, by comparing the signal obtained by integrating the output of a sensor and the signal corresponding to the output signal of the sensor and further integrating the compared output while comparing this integration signal with a reference signal to output the same. CONSTITUTION:A sensor 1 outputs the signal based on a light receiving element as V1 while this output V1 is outputted as an integration signal V2 through an integrating circuit 2. Further, the output V1 is divided to voltage V3 by a voltage divider circuit 3. These voltages V2, V3 are compared by a comparator circuit 4 and, if either one of them becomes higher, both outputs are reversed. In the next step, output VO outputted from the comparator circuit 4 is further integrated by an integrator circuit consisting of a resistor R13 and a condenser C2 to be supplied to a comparator 40 as voltage V6 while reference voltage V6 is supplied to the comparator 40. Therefore, even if the output VO of the comparator 4 comes to H by a noise signal, the output thereof is integrated and, therefore, the output VO comes to L before voltage V5 becomes higher than V6 and erroneous detection caused by noise can be prevented and the detection of paper can be performed with higher accuracy.

Title: Optical character reader
Inventor: SHIMOYAMA MASAFUMI
IPC: G06K9/20
Filed: 1995-09-18
Abstract: PROBLEM TO BE SOLVED: To accelerate the processing speed of an OCR and to reduce power consumption. SOLUTION: For characters printed or handwritten on a slip, image data are generated by an image input part 1 and an A/D conversion and level correction part 2 and written in a write data FIFO 3. When the data are written in the write data FIFO 3, a state machine inputs a 'write request', shifts from an IDL state st1 to a W state st2, executes a write cycle and increases a write address counter 6. When the read of the data is requested from a recognition control part 10 and the 'write request' is not present, transition from the IDL state st1 to an R state st3 is performed, a read cycle is executed and a read address counter 7 is increased. The recognition control part 10 takes out the data and recognizes them as character patterns.
