Title: Agc circuit
Inventor: NEMOTO YUKIO
IPC: H03G3/30
Filed: 1990-05-10
Abstract: PURPOSE:To realize an AGC circuit with less effect of ambient temperature and fluctuation of a power supply voltage and giving easily a stable performance by providing the circuit constitution such that a 3rd resistor whose resistance is twice that of a 2nd resistor connects to a connecting point between 1st and 2nd transistors(TRs) via a current mirror circuit. CONSTITUTION:A current source consists of a resistor R1, a TR Q1, a diode Q2, a TR 4 and a resistor R5. A voltage VD across the diode Q2 is set as VD= VBE and a current of IO VBE/R5 flows to a collector of the TR Q4, where VBE is a base-emitter voltage. An operating point of the filter circuit comprising a resistor R7 and its succeeding components is selected around 2VBE of TRs Q10, Q11 and has a temperature characteristic of 2VBE. Since 1VBE is compensated by the diode Q9, a voltage across the resistor R6 has only to be selected to be 1VBE. When the relation of R6=2R5 exists, the temperature of the filter circuit is completely compensated.

Title: Stencil printing press
Inventor: SHOJI MASASHI
IPC: B41L13/04
Filed: 1987-05-19
Abstract: PURPOSE:To make a stencil at a time to conserve time, by a method wherein, the stencil is made directly on a stencil base paper wound around a printing drum by successively changing over a digital input, an optical input, and others with regard to the stencil base paper. CONSTITUTION:A printing press is provided with a stencil forming device 40 applying a stencil processing directly on a stencil base paper on a printing drum 7 with an output from a change-over switch 3. A roller 8 is disposed in the intermediate part of a stencil roll 5 and the printing drum 7 to guide the feeding of the stencil base paper. In this construction, a digital input to a 1st plate, e.g. character data, and an optical input to a 2nd plate, e.g. image data, are changed-over in order by the change-over switch 3 to be appropriately stencil-processed on the stencil base paper on the printing drum. Therefore, since the need for winding the plates around the printing drum after a stencil processing is separately applied to the plates, for example, successively to the 1st plate and the 2nd plate, in a conventional manner is eliminated, a required time can be reduced.

Title: Heat development type diazo copying material
Inventor: WATANABE HIDEO
IPC: B41M5/40
Filed: 1981-07-31
Abstract: PURPOSE:To reduce the loss of heat energy and to obtain a uniformly developed copy with a heat development type diazo copying material by imagewise exposing the surface of the photosensitive and heat sensitive layer and converting the formed latent image into a visible image by heating. CONSTITUTION:A photosensitive and heat sensitive diazo layer 2 contains a diazo compound, a coupling component and an auxiliary coupler as principal components, and a back layer 3 contains a colored substance which is decolored by absorbing radiant energy. A latent image is formed in the layer 2, and by supplying radiant energy from the back side, heat is allowed to be absorbed in the colored substance in the layer 3 to carry out development. Since the colored substance is decolored by radiant energy, the back side of the resulting copy is made white. Radiant energy is efficiently absorbed, and development can be carried out without bringing the material into contact with a heating member. Accordingly, the loss of heat energy is reduced, and a uniformly developed copy is obtd.

Title: Ecl logical circuit
Inventor: AONO KUNITOSHI
IPC: H03K3/289
Filed: 1983-07-01
Abstract: PURPOSE:To save power consumption without deteriorating the speed characteristics of a circuit by reducing gate current flowing to a data holding gate. CONSTITUTION:A gate current source is used in common for a data fetching gate of a master FF1 and a data holding gate for a slave FF2 which are actuated at the same phase and the gate current ratio of the gates is determined by a resistance ratio. Since the emitter voltages of ECL gates G1, G4 are almost equal when the ECL gates G1, G4 are in the operating status, the current ratio between the data entering gate G1 and the data holding gate G4 can be determined by the resistance ratio R2:R1, and if R2 is extremely larger than R1, the gate current of the data holding gate G2 can be sufficiently reduced.

Title: Chromate treatment of plated steel plate
Inventor: KOSHIISHI KENJI
IPC: C25D5/26
Filed: 1981-08-03
Abstract: PURPOSE:To form a chromate skin film having corrosion resistance, processability and close adhesiveness of a paint to a plated steel plate, by treating said plated plate with a treating liquid with a specific composition prepared by adding a silane coupling agent to chromic anhydride to reduce a part thereof. CONSTITUTION:A silane coupling agent is added to a chromic anhydride(CrO3) solution to reduce a part of chromic anhydride to adjust the concn. of chromic anhydride to 0.1-1mol/l and a mole ratio (Cr<+3>/Cr<+6>) to 0.05-0.7 in the composition of the liquid. This liquid is coated on the surface of a plated steel plate as a treating liquid by an appropriate method and dried thereon. By this method, chemical change such as crosslinking reaction is generated to form a strong chromate skin film. In addition, because this chromate treating method is a coating type, the treating liquid is not aged and, therefore, it is unnecessary to treat a waste liquid.

Accordingly, the heat of the mounted parts 5 is transmitted to the insulator layer 20 at the center, and the air inside the ventilation ports 30 gets at high temperature, and by the convection phenomena of the air being heated, the inside of the printed wiring board is cooled. Moreover, the heat of the mounted parts 5 is radiated directly from the surface of the mounted parts 5 and the surface of the outside conductor layer 12-2. On the other hand, the printed wiring board 10 does not have a metallic core, so there is no fear of corrosion, and it becomes light and easy in handling.
