Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To prevent the increase in losses due to the advance phase mode, and lower the current pulsation by changing switching frequency and modulating pulse width, in response to an instantaneous value of voltage of an alternating current power source. SOLUTION: Value of the instantaneous voltage of an alternating current power source which is detected by a full wave rectifier 4, and the reference voltage of a reference voltage generating circuit 5 are compared with each other, so as to decide the switching frequency of an inverter circuit 3. An adder 6 subtracts the output voltage of the reference voltage generating circuit 5 from the output voltage of the full-wave rectifier 4, so as to output the deviation thereof. A carrying wave generating circuit 7 oscillates the switching frequency of MOSFETs, Q1, Q2 of the inverter circuit 3 on the basis of the output signal of the adder 6. A modulation wave generating circuit 8 generates the signal for deciding the pulse width in relation MOSFETs to Q1, Q2.

Abstract: PURPOSE:To obtain an image with superb gradation density, excellent light-fastness and fixing properties as well as satisfactory high density and enable efficient data recording using a recording material described below by forming a layer containing a color expressed by a specific formula. CONSTITUTION:A recording material consists of a thermal layer containing a color shown by formula I provided on a support, and the color is a cyan color having excellent heat dissipation and heat resistance.

By reproducing a recorded tape with a prescribed procedure, signals having the frequencies of f1, f1+DELTAf, f1-DELTAf, -, f1+4DELTAf and f1-4DELTAf are reproduced. The frequencies and the reproducing voltages of these signals are measured by a spectrum analyzer 12 and an arithmetic operation is performed by the computer 13. Thus, the recording current versus the reproducing output characteristic when the frequency is f1 can be obtained in a shape of curve 15.

Title: Heat-resistant cushion material for molding press
Inventor: HYODO KENJI
IPC: B29C43/20
Filed: 1986-09-01
Abstract: PURPOSE:To obtain a cushion material for a molding machine which is used at the time of molding, by a method wherein wet paper composed of a specific heat-resistant polymer is molded and an arbitrary number of sheets of wet paper are laminated after water content of the wet paper has been controlled so as to fall within a specific range, which is unified by drying through dehydration under heating and pressurization. CONSTITUTION:Wet paper is molded by performing sheet forming of aqueous slurry obtained by mixing a fine inorganic fiber whose fiber diameter not containing shot practically is 0.5-1.5mum and fiber length is 70-1,000mum and pulley particles of a heat-resistant aromatic polymer whose water filtering value is 150sec or more and less than 500sec with each other. After an arbitary number of sheets of wet paper, whose water content has been controlled to 50-95%, have been laminated, the same is unified by drying through dehydration under heating and pressurization. Interlaminar bonding of sheets of paper is performed sufficiently as mentioned above and a cushion material superior in cushioning function, mechanical strength, heat resistance and durability is obtained. When water content is lower than 50%, in the case where the sheets of wet paper are dried by laminating them, interlaminar bonding of sheets of paper is weak and they are not turned into a monolithic cushion material. When the water content is higher than 95%, the wet paper is collapsable, lamination is difficult and cracks are generated during pressurization and heating.

Title: Antistatic photosensitive laminated film
Inventor: HAYASHI KANJI
IPC: H05K3/00
Filed: 1987-08-17
Abstract: PURPOSE:To easily suppress the generation of an electrostatic charge voltage in a process for producing a film and to improve the yield of a printed wiring board or the like which is the final product by subjecting a protective layer or both of a backing layer and the protective layer to an antistatic treatment. CONSTITUTION:The kneading of an antistatic agent into the backing layer 1 and the protective layer 2 or the coating of said agent on the surface of said layers is preferable as the antistatic treatment to be executed on said layers. However, the method of kneading the antistatic agent to the layers has the possibility of bleeding of the antistatic agent onto the surface of the layer to which said agent is kneaded and the consequent change or deterioration in the properties of a photoresist photosensitive layer 3 by the migration of said agent to the photoresist photosensitive layer particularly in such a case when the film consisting of the photosensitive laminated body is preserved for a long period of time. The method for coating the antistatic agent includes a method of executing the coating after the production of the conventional photosensitive laminated film consisting of the three layers or a method of previously coating the antistatic agent on the side to be formed as the backing and protective layers. The stripping electrostatic charge voltage to be generated in the photoresist photosensitive layer is thereby extremely lowered.
