Title: Median filter circuit
Inventor: TOMIKAWA KAZUYA
IPC: H03H17/00
Filed: 1988-12-01
Abstract: PURPOSE:To eliminate malfunction against the change of window width by nullifying only the content of waveform recombination data in waveform data output means whose number is reduced when a reset means reduces the number of (2K+1) waveform output means to 2(K-n)+1. CONSTITUTION:In the case of reducing, for example, (2K+1) (K=1, 2, 3...) window width W to 2(K-n)+1(K>n=1, 2, 3...) window width W, the waveform recombination data HDD of the waveform data output means Mn and Mn whose operating functions are stopped or the waveform output means M1-Mi whose operating functions are not stopped are nullified once by the reset means 15. Therefore, the content HDD of the waveform recombination data in the waveform output means Mn and Mn whose operating functions are stopped compress the number of window width to 2(K-n)+1, which disconnects relationship to the logical operation of waveform recombination in the waveform output means M1-MS. In such a way, it is possible to eliminate the malfunction due to an offset quantity, etc., against the change of the window width.

Abstract: PROBLEM TO BE SOLVED: To implement a withstand voltage test only by the operation from outside an airtightly closed container without the release of insulating gas by making a conductor connected to a gas-insulated switchgear and a conductor connected to the head of a bushing in a rotatable structure. SOLUTION: A conductor 7 of a gas-insulated switchgear 3 and a contractor 10a of a contacting section 10 at the head of a bushing 9 are connected with conductors 15, 16 which can rotate around rotary shafts 15a, 16a. The rotary shafts 15a, 16a are rotatably installed in a conductor 18 which is insulatedly supported by an insulating support 17 in a container 20 and are extracted outside the container 20. The conductors 7 and 15 are connected to each other through contractors 19a, 19b which are insulatedly supported by a spacer 4 installed in an opening formed in the side of the container 20. Owing to this structure, the conductors 15 and 16 can be brought into contact with a contractor 22a by rotating them around the rotary shafts 15a and 16a respectively. As a result, a withstand voltage test can be conducted only by the operation from outside without the release of insulating gas.

Title: Self-oscillation circuit
Inventor: TOKUDA KATSUMI
IPC: H02M7/537
Filed: 1992-10-16
Abstract: PURPOSE:To make oscillating frequency stable and to attain inexpensive circuit configuration with less number of components. CONSTITUTION:An OFF pulse is outputted from an oscillator and oscillated at a stable frequency (f). The frequency (f) of the OFF pulse is higher than an oscillated frequency f0 of the self excited oscillator circuit. When a capacitive component is fluctuated due to dispersion in the capacitive load, the oscillating frequency is fluctuated. However, the OFF pulse whose frequency is (f) is fed to the base of a transistor (TR)Q1 via a TRQ4 when the TRQ1 is turned on to synchronizingly turn off the TRQ1. Thus, the TRQ1 is forcibly turned off through synchronization with the OFF pulse. Then the oscillation is stably continued at the frequency (f) by synchronizing the TRQ1 with the OFF pulse whose frequency is (f).

Title: Manufacture of developer
Inventor: HIROTA NORIAKI
IPC: G03G9/08
Filed: 1990-11-09
Abstract: PURPOSE:To enable the fluidity of a developer to be maintained for a long period by implementing a process for applying a fluidity assistant additive before a classification process in the manufacture process for the developer. CONSTITUTION:A classification process for eliminating unnecessary fine toner particles in the manufacture of toner particles, is implemented after the additive application process where the toner particles and additives are mixed with each other. In other words, the additives are mixed with a toner particle group containing the fine toner particles, and thereafter excessive additives are eliminated, together with the fine toner particles. When a developer so manufactured is used with an actual machine, the amount of the additives acting as fluidizing agents becomes constant, due to the non-existence of excessive additives, and the fluidity of the developer can be maintained for a long period.

Title: Operation controller of packaging machine
Inventor: SUGA YASUTAKA
IPC: B65B57/00
Filed: 1994-11-14
Abstract: PURPOSE: To smooth operation control without loading a frame having a heavy load frame on control variable speed function by controlling drive of a motor for carrying objects to be packaged, a film transfer motor and a seal bar open/ close motor synchronously with rotation of a seal frame reciprocating motor. CONSTITUTION: While a lever 66 is swung by a rotating lead of a cam 62 rotating at a constant speed by a motor 55, a frame 29 is reciprocated by the swing of the lever 66. Rotation of this motor 55 is converted into a pulse signal by an encoder 84 and input to a controller 85 for processing, and an output signal from the controller 85 is sent to respective motors 56, 57, 58 through a synchronizer, whereby the motor 56 for supplying objects to be packaged, the motor 57 for carrying a frame and the motor 58 for opening/closing a seal bar are respectively rotated synchronously with the motor 55. Further an inverter between the synchronizer and the motor 58 controls opening/closing of seal bars 52, 53 with timing aligned with reciprocation of the frame 29. Thus a load to a motor at the time of varying motor speed can be reduced.

Filed: 1987-12-01
Abstract: PURPOSE:To suppress a bird's beak by oxidizing with a patterned silicon oxynitride film as an antioxidation mask, thereby selectively forming a field oxide film in an element isolating region. CONSTITUTION:After a silicon oxynitride film 12 having 1.6-1.9 of refractive index is deposited 500-3000Angstrom  thick by a CVD method directly on a semiconductor silicon substrate, it is patterned to form an element isolating region by a normal photoetching step, and it is oxidized with the patterned oxynitride film as an antioxidation mask, thereby selectively forming a field oxide film on the element isolating region. Since the oxynitride film having 1.6-1.9 of refractive index by the CVD method has a property of small stress, a crystal defect is a semiconductor substrate can be suppressed without forming a pad oxide film on the substrate 11. The oxynitride film has sufficient antioxidation property by suitably selecting a suitable thickness in response to the conditions of a temperature at the time of field oxidizing, oxidizing time, etc.
