Abstract: PURPOSE:To bond a heat sink to a lead frame at a first glass transition temperature and to enhance molding resin in adhesion to the heat sink at a second glass transition temperature by a method wherein a laminated adhesive layer is composed of first and second adhesive agent different from each other in glass transition temperature CONSTITUTION:A high Tg adhesive layer 2a of thermoplastic polyimide is applied onto both sides of an OFC1/2H (oxygen-free copper) plated with Ni, and a low Tg adhesive layer 2b is applied onto the upper high Tg adhesive layer 2a to form a laminated adhesive layer. A heat sink 2 is blanked out of the OFC1/2H and brought into close contact with a lead frame 4. By this setup, the low Tg adhesive layer 2b is molten to grow high in adhesion, and the lead frame 4 is bonded to the low Tg adhesive layer 2b. On the other hand, the high Tg adhesive layer 2a is not molten and interposed between the low Tg adhesive layer 2b and the lead frame 4 as an insulating layer. Therefore, an insulating process can be simplified, and a semiconductor device of this constitution can be lessened in manufacturing cost.

Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To expand a delay control range with a simple configuration and to improve adjustment resolution of a horizontal screen position by deciding the control range of delay quantity of a variable delay circuit, based on delay information of a dummy circuit that includes the same delay element as the variable delay circuit. SOLUTION: When a horizontal processing system is integrated in an LSI, a dummy circuit 6 which is constituted of an inverter of the same element and has the same delay is arranged in the neighborhood of a variable delay circuit 5 on the same chip. A delay detecting means 7 detects the oscillation frequency of a ring oscillator provided in the circuit 6, that oscillates in accordance with the delay in the inverter. A CPU 8 calculates the delay quantity per inverter stage of the circuit 5 from oscillation frequency information and decides the delay range of the circuit 5, based on delay quantity equivalent to one clock of a clock signal A of a minimum value that can be delayed by a pulse generation circuit 4 and delay per inverter stage. As a result, it is possible to control a horizontal screen position control pulse with a resolution that is one clock A or lower.

Title: Liquid-crystal electrooptic element
Inventor: AOKI KAZUO
IPC: G02F1/1341
Filed: 1986-04-25
Abstract: PURPOSE:To shorten liquid crystal enclosing times of a nematic and smectic liquid crystal, by beveling one side of, at least, one of upper and lower base plates and providing liquid crystal pouring holes in the one side. CONSTITUTION:A lower base plate 1 whose face 6 is beveled and upper base plate 2 are joined to each other with a sealing material 4 in between. Since an empty cell is manufactured by forming pouring holes 3 with the sealing material 4 so that the length of the opened sections can become 50% of the length of one side and filled up with liquid crystal, enclosure of the liquid crystal is performed under a condition where the inside and outside of the cell is set to a vacuum condition. If the whole panel is maintained at a high temperature at the time of enclosure of liquid crystal, the liquid crystal compound efficiently gathers around the holes 3 by a capillary action and uniformly diffused throughout the beveled side. Therefore, smectic liquid crystal can be enclosed in a short time in the same manner as that used until now even if the number of the pouring holes is increased.

Title: Water-swellable, water-stopping and water-retaining material
Inventor: SASAYAMA KOUJI
IPC: C08L33/02
Filed: 1984-05-16
Abstract: PURPOSE:To obtain a water-retaining material which causes neithr dropping of gel, nor dissolution of a water-soluble component during water absorption and expansion, and exhibits stable water-stopping performance under drying conditions, by incorporating a coupling agent in a compsn. contg. a water-insoluble, high-molecular material and a highly water-absorbing resin. CONSTITUTION:A coupling agent is incorporated in a water-swellable compsn. contg. a water-insoluble, high-molecular material and a highly water-absorbing resin. Since the bonding force between the water-insoluble, high-molecular material and the highly water-soluble resin is increased by using the coupling agent, the resulting water-retaining material has improved physical properties such as tensile strength, and causes neither dropping of gel component from the highly water-absorbing resin nor dissolution of water-soluble matter out of the resin when expanded by water absorption. Further, when the material is placed under such conditions that it is dried after the expansion by water-absorption, it is prevented from being dried so that stable water stopping performance can be exhibited. Preferred examples of the coupling agents are silane coupling agents, aluminum coupling agents and titanate coupling agents.

IPC: F02M51/08
Filed: 1984-05-16
Abstract: PURPOSE:To reduce the generation of fuel steam and to enable given fuel to be alway fed through a nozzle, by a method wherein a passage, through which fuel flows, is located between the outer periphery on the inner side of a bobbin, around which a coil is wound, and the wall surface, which is positioned opposite to the outer periphery of the bobbin, a core positioned concentrically with the bobbin. CONSTITUTION:With a coil 3 energized, a plate 7 is sucked to rais a ball valve 6, which is separated from a valve seat 13. Said opening of the valve causes fuel to flow through an inlet passage 18 and be injected through a nozzle 17 by means of an oblique hole 15 in a swril orifice 16 as an eddy flow is produced. Further, an annular passage 26 is formed between the outer periphery on the inner side of a bobbin 2, around which a coil 3 is wound, and the wall surface of a core 1. This causes fuel steam, generated at the upper surface of the coil 3, to be exhausted through an outlet passage 22 by means of the annular passage 26. Further, the outer periphery on the inner side of the bobbin 2, around which the coil 3 is wound, is cooled directly by fuel to reduce the generation of fuel steam.

CONSTITUTION:At the time of arc-sensing horizontal plate base materials W1 and W2, welding is performed in order on first-forth weaving end points WP1-WP5 from the welding starting point P3 and the welding currents PI1-PI4 in the vicinity thereof are obtained. In addition, at the time of performing welding on between the end point WP1 and the end point WP2, an average current value Ic1 is calculated from the welding currents for a specified time at the intermediate position 20 between the end point WP1 and the end point WP2. Welding is then performed on between the end point WP4 and the end point WP5 and an average current Ic of the central part 20 thereof is obtained and the interval between the end point WP4 and the end point WP5 is known and the height of a welding torch is derived by comparing the average current Ic with the average current Ic1. Consequently, even if the groove width is changed, the weaving width can be regulated with high accuracy.
