Title: Forward converter for improving higher harmonic characteristics of power supply
Inventor: MATSUI KAGEKI
IPC: H02M7/06
Filed: 1992-04-09
Abstract: PURPOSE:To improve higher harmonic characteristics of power supply by adding a feedback signal fed from an error amplifier to a feedforward signal which detected a DC link voltage and applying a sum signal to a pulse width modulation circuit in order to suppress ripple through PWM control of a switching element thereby reducing the capacity of a smoothing capacitor. CONSTITUTION:Power supply input current is rectified through a rectifying circuit 1 and smoothed through a smoothing capacitor 2 to produce a DC link voltage Vc. The DC link voltage Vc is then converted through a semiconductor switching element 3, a transformer 5 and a secondary rectifying circuit 6 into a DC stabilized voltage Ve. A feedforward signal Fw, which detected the DC link voltage Vc, is fed through adder 8 to a PWM circuit 9 which delivers an output, corresponding to the feedforward signal Fw, to the switching element 3 thus achieving constant voltage characteristics of the output voltage Ve. This constitution reduces higher harmonic current by reducing the capacity of the smoothing capacitor 2 and suppresses ripple by means of the feedforward signal.

Title: Version-up system for software
Inventor: SAITO TAKAHIRO
IPC: G06F12/00
Filed: 1990-04-03
Abstract: PURPOSE:To reduce the work load caused by the version-up of software by distributing automatically the software of a new version via a version control means. CONSTITUTION:A version control server 6 detects the updating of software when the software is distributed to the file service function of a file server 9. At the same time, the server 6 knows the destinations of distribution with inquiries given to the software control data bases of the data base servers 10 and 14 and distributes the software by means of the fiel service functions of both file servers 9 and 13. Thus the software of a new version is automatically distributed via the version control service of the server 6. As a result, the simple work load due to the version-up of software can be reduced.

Title: Knob structure for interphone
Inventor: YAMADA MANABU
IPC: H04M1/06
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To recognize the position of a handset at night even if illumination does not exist by forming a gap between a case and the handset, leaking the emitted light of an LED at the time of call incoming, forming a hook knob with a material through which light permeates, permeating the emitted light of the LED when a call terminates and automatically radiating light. SOLUTION: A hook knob 1 and an LED 3 fitted to a substrate 2 positioned below the hook knob 1 are fixed to a case 5 where a handset 4 is stored. The hook knob 1 is formed of a material through which light permeates and permeates the light of the LED 3. Before the time of an incoming call, the hook knob 1 is below the handset 4. Even if the hook knob 1 emits light, it cannot be viewed from the outside at the time of the incoming call. The light of the LED 3, which is emitted at the time of the incoming call or during the call, leaks from a gap part 6 between the case 5 and the handset 4. Thus, the position of the handset 4 can be recognized and a position returned to the case 5 can be recognized by light permeated through the hook knob 1 when the call terminates.

Title: Manufacture of ink jet head
Inventor: UEISHI YUKIHIRO
IPC: B41J2/16
Filed: 1986-04-16
Abstract: PURPOSE:To enhance a manufacturing accuracy and to reduce a process, by a method wherein, in forming of nozzle substrate, a metal chrome of a specific thickness is formed on an abraded glass and thereon a circular pattern of photo resist is formed, and thereon an electrodeposit film of a specific thickness is deposited and thereafter separated from the surface of the metal chrome film. CONSTITUTION:An abraded glass 2 having a sufficient smoothness is used as a substrate. On the substrate, a sputtered film 3 of pure metal chrome (800-3,000Angstrom ) is formed in order that an electrodeposit film can be easily peeled later, and thereon a spin coated positive photo resist film is formed. After being prebaked, the photo resist film is exposed by using a predetermined photo mask and developed and postbaked, thus resulting in a circular projected portion 4 formed on the sputtered film 3. Since the sputtered film 3 is conductive, the above material is introduced into an electrodeposition tank as it is to obtain a nickel electrodeposit film of 10-50mum thickness having a shape of an orifice plate 1. Thereafter, the orifice plate is separated from the chrome sputtered film. In this manner, a process is simplified and a cost can be reduced.
