Title: Resin sealed type semiconductor device
Inventor: YUKI YUUICHI
IPC: H01L23/28
Filed: 1981-11-11
Abstract: PURPOSE:To obtain excellent bonding with a synthetic resin and prevent infiltration of water by executing the anode oxidation processing to the regions except for the main surface of a heat radiating plate and an extruded portions of lead. CONSTITUTION:The surface layer is converted to CuO by executing the anode oxidation to the regions except for a main surface of a heat radiating plate and the extruded portions 1a, 1b of lead. In this case, the already deposited Ag layers 11a...11n are not changed and protective processings are unnecessary. When a CuO is formed, bonding with a synthetic resin 3 becomes excellent and any water can no longer infiltrate from the bonding surface and thereby reliability of an electrical characteristic of a semiconductor device can be improved.

A primer layer 3 is formed on at least either of the surfaces of a metal sheet 1 optionally provided with a formation layer 2 by applying a primer based on a phenolic resin and the above rubber composition is applied thereto and vulcanized and backed to form a rubber layer 4 of a thickness of 10-300mum and a nonadhesive layer 5 is optionally formed on the rubber layer 4.
Patent JP-S6239259-A (JP)
Title: Thermal head
Inventor: YAMAMURA NORIO
IPC: B41J2/38
Filed: 1985-08-15
Abstract: PURPOSE:To improve heat response, by a method wherein a space provided under a heating resistor is filled with a liquid which is to vaporize to form bubbles when the heating resistor is heated. CONSTITUTION:Starting of current-supply to a heating resistor 3 through electrodes 4a, 4b causes a liquid to start vaporizing, which produces a bubble 6 in a chamber 2. As the temperature of the heating resistor 3 increases, the bubble 6 grows to nearly fill the chamber 2 and to come into contact with the heating resistor 3. Therefore, the heat transfer from the heating resistor 3 to an alumina substrate 1 is substantially prevented, which results in a sharp temperature rise rate at a rise time. On the other hand, stopping of current-supply leads to the temperature decrease of the heating resistor 3 which causes the vaporized gas to return to liquid, whereby the bubble 6 in the chamber 2 starts shrinking at high speed. The liquid which has nearly filled the chamber 2 further decreases the temperature of the heating resistor 3, whereby the bubble 6 is eliminated and then the chamber 2 is filled with the liquid. As a result, the heat is transferred to the substrate 1 through the liquid, which allows the chamber to be cooled down at high speed. In this manner, the temperature increasing/decreasing properties of the heating resistor are improved, which results in the thermal head with superior heat efficiency and good heat responce.

Title: Method and device for transmitting information signal
Inventor: KANO SHUNSUKE
IPC: H04L25/49
Filed: 1989-07-12
Abstract: PURPOSE:To detect the bending abnormality of a signal line or fault on a transmission side by transmitting a normality confirmation signal, which waveform is different from that of an information signal, when the transmission of information is not executed. CONSTITUTION:When a system is activated, the halfwave-shaped normality confirmation signal is transferred from a signal output circuit 1 to a signal input circuit 2 by a diode D1. On the signal output circuit 1 side, an operator operates a switch Sw. While the switch Sw is turned ON, an alternative current signal is sent to the signal input circuit 2 and while the switch Sw is turned OFF, a halfwave-rectified signal similar to the normality confirmation signal is sent to the signal input circuit 2. On a reception side, a class for the two kinds of the signals is identified by detecting difference in the waveform of the signal.

Title: Water-resistant adhesive
Inventor: TOKUDA MASAHIRO
IPC: C08G18/00
Filed: 1981-11-10
Abstract: PURPOSE:To provide a low-cost adhesive with excellent workability and water- resistant bonding power, consisting mainly of (A) suspension of half-esterified starch obtained by esterifying a mixt. of starch with dibasic acid (anhydride) and(B) isocyanate compd. CONSTITUTION:Isocyanate compd. having at least two isocyanate groups at the terminal of molecule (e.g. tolylene diisocyanate) is added to suspension of half- esterified starch to effect crosslinking. The half-esterified starch is obtained by adding dibasic acid anhydride) (e.g. malic or maleic acid) to 1 mol of gulcose unit of starch to effect esterification. If necessary, aqueous rubber latex is also added for crosslinking. When the amount of the dibasic acid (anhydride) falls within the above range, a stable suspension in which half-esterified sarch is suspended in a non-paste state is obtained and, upon heating, the starch particles are converted to paste with a high viscosity. Thus, excessive penetration of adhesive into adherend is prevented in thermocompression bonding and consistent bonding is insured.

Title: Light quantity control method for semiconductor laser
Inventor: KARASAWA TAKEMI
IPC: H04N1/04
Filed: 1989-07-14
Abstract: PURPOSE:To enable high-accuracy, inexpensive light quantity control by adding a current corresponding to light quantity command information to a feedback current and driving a semiconductor laser. CONSTITUTION:A current I3 is amplified by an amplifier A1 to correspond to light quantity command information and become part of a current supplied to a semiconductor laser by a signal line L9. Namely, the current I3 corresponding to the light quantity command information is added as the current which drives the semiconductor laser to minimize the controlled variable of a feedback loop. Therefore, the light output of the semiconductor laser can be held constant by controlling only variation in the substantial light output characteristics of the semiconductor laser due to an environmental change such as temperature variation, and even if the light quantity command value is varied optionally, the controlled variable does not vary, so that a feedback current I4 which controls the semicondutor laser has only minimum variation. Consequently, a high accuracy light quantity control is performed even by an inexpensive digital analog converter which consists of a small number bits.
