Title: Liquid crystal display driving circuit
Inventor: OGAWA FUMIHIRO
IPC: G09G3/36
Filed: 1992-03-09
Abstract: PURPOSE:To provide a driving circuit to realize a 16-gradation liquid crystal display, not as an extension of an 8-gradation driving circuit. CONSTITUTION:A liquid crystal display driving circuit is provided with a voltage selector 3 to select one value among an 8-value voltage level by means of subordinate 3 bits in 4-bit display data and a circuit to select whether this selected voltage is outputted as it is or outputted through a level shifter by means of '0' or '1' of the lowermost one bit in the 4 bit display data. That is, a 16-value voltage level is realized by means of a switching matrix of 8X2 and a single level shifter 4. The liquid crystal display driving circuit capable of 16-gradation display can be realized only by adding several additional circuits to a conventional 8-gradation driving circuit.

IPC: C25D11/22
Filed: 1983-03-28
Abstract: PURPOSE:To provide a titled coloring method by which an extremely thin anodic oxide film can be easily colored to a dark color tone by subjecting an Al metal to a primary electrolytic treatment to form an anodic oxide film having a prescribed film thickness or below then subjecting successively the film to an AC secondary electrolytic treatment and a dyeing treatment. CONSTITUTION:An Al metal, i.e., pure Al or Al alloy is subjected to a primary electrolytic treatment to form an anodic oxide film of <=12mu, more specially <=9mu thickness thereon. The Al metal formed thereon with the anodic oxide film is subjected to an AC secondary electrolytic treatment using a metallic salt-contg. electrolytic bath in which, for example, nickel sulfate and stannous sulfate are combined. The concn. of the metallic salt in this case is usually 5-100g/l, the pH is 0-5 and the bath temp. is 0-50 deg.C. The surface of the Al metal after the secondary electrolytic treatment is then dyed by using various commercially marketed dyes. As a result, the easy dyeing of the Al metal to various desired dark color tones particularly of dark red, dark brown, dark purple, etc. even if the thickness of the film by the above-described primary and secondary treatments is considerably thin as compared to the thickness by the prior art is made possible.

IPC: H03H9/64
Filed: 1990-03-02
Abstract: PURPOSE:To obtain a filter capable of suppressing the generation of ripples in a band to a low level and having high performance by arranging respective intersecting parts of weighted interdigital electrodes in the vicinity of a hot terminal. CONSTITUTION:The intersecting parts S1 to S6 indicating the weighting value of the weighted interdigital electrodes 11, 14 arranged on a piezo-electric base are arranged close to a bus bar 12 connected to a hot side terminal 1 and the electrode 14 connected to a grounded bus bar 13 is arranged so as to be extended up to the intersecting parts S1 to S6. Since the length of the hot side electrode 11 can be shortened and the total area of the electrode 11 connected to the hot side terminal 1 can be minimized, the influence of unnecessary waves oscillated by an electric field formed in the thickness direction of the base can be suppressed. Consequently, ripples generated on the filter characteristics in the band can be suppressed to a low level.

Title: Expansion valve
Inventor: WATANABE JUN
IPC: F25B41/06
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To stabilize operation concerning an expansion valve in a refrigerating cycle by making a friction force between a valve body and a valve body receptacle larger than that between the valve body and a valve seat in a state where the valve body partially contacts the valve seat to eliminate quick closing of a valve when the pressure of a high pressure refrigerant on the upstream side rises. SOLUTION: In this expansion valve, an inlet side end part of a low pressure refrigerant passage formed on a body block is connected to an outlet of an evaporator and an outlet side end part of a high pressure refrigerant passage to an inlet of the evaporator. The high pressure refrigerant passage is formed into a restriction 15 in the course thereof and a ball-shaped valve body 21 is arranged on a valve seat 20 at an opening part on the upstream side thereof. In this case, a valve receiving hole 16a is formed in a valve body receptacle 16 so that the diameter (d) of a contact circle where a contact part between the valve body 21 and the valve body receptacle 16 is about three-quarter as much as the diameter D of the valve body 21.  Thus, the friction force between the valve body 21 and the valve body receptacle 16 is made gradually larger than that between the valve body 21 and the valve seat 20 to keep the space between the valve body 21 and the valve seat 20 from being closed completely as caused by a short-time rise in pressure.

IPC: H01H33/59
Filed: 1989-03-03
Abstract: PURPOSE:To prevent destruction of a switching element or production of an abnormal high voltage by controlling a positive or negative switch unit individually in response to the polarity of a detected main circuit current. CONSTITUTION:Semiconductor switching elements 301, 302 in switch units 300P, 300N are reset, which are provided to flow a current of the opposite direction to the direction of a main circuit current when an off signal is given. Then, the main circuit current at that time is commutated to diodes 302, 304 connected in anti-parallel with the semiconductor switching elements 301, 302 respectively. Thus, the main circuit current does not flow after the zero point. That is, the positive or negative switch unit 300P or 300N is controlled individually in response to the polarity of the detected main circuit current to interrupt the current surely at the zero point so long as the polarity is detected even when the level of the main circuit current is lowered. Thus, the production of an abnormal high voltage and the destruction of the semiconductor switching elements 301, 302 is prevented.
