IPC: H01L23/02
Filed: 1987-01-16
Abstract: PURPOSE:To prevent an IC package from becoming defective by the adhesion of a bonding agent to optical glass by a method wherein the bonding agent is coated on the package side. CONSTITUTION:The title IC package is manufactured by performing a process in which a bonding agent is coated on the surface of the package 1, and another process wherein the package and an optical glass 7 are laminated. First, the bonding agent such as low melting point glass 2 is coated on the package 1 made of ceramic and the like. At this time, the package 1 does not become defective even when a small quantity of low melting point glass 2 is adhered to the package 1, whereas the package becomes defective when the bonding agent is adhered to the optical glass 7. Then, when the low melting point glass 2 is temporary sintered, the low melting point glass 3 adhered to the package 1 becomes hard and it causes no problem. The optical glass 7, which becomes a cover, and the package 1 on which low melting point glass 2 is coated are adhered by laminating them and performing a heat treatment thereon. As a result, the yield of production of the title IC package can be enhanced, and the cost of its manufacture can also be cut down.

Title: Carbon fiber reinforced resin composite material and prepreg
Inventor: MATSUHISA YOJI
IPC: A63B53/10
Filed: 1994-01-28
Abstract: PURPOSE:To obtain a carbon fiber-reinforced resin composite material which is excellent in impact resistance characteristic by reinforcing the composite material with carbon fiber wherein specific gravity is a specific value or lower, tensil elastic modulus is a specific value or higher, tensil strength is a specific value or higher, and peel strength at end of plate is a specific value or higher. CONSTITUTION:For carbon fiber composing carbon fiber reinforced resin composite material or prepreg, specific gravity is 1.75 or lower, tensile elastic modulus and tensile strength which are measured by a strand tensile test are respectively 29tf/mm<2> or higher and 500kgf/mm<2>, and peel strength at end of plate measured by a composite test is 22kgf/mm<2> or higher. For carbon fiber of which specific gravity is larger than 1.75, neight reducing effect is small. Further for carbon fiber wherein tensile elastic modulus is under 29tf/mm<2>, and tensile strength is under 500kg/mm<2>, impact resistance is low, and besides thick composite material is necessarily produced in order to develop a specific characteristic. Then, merits by the weight-reduction are decreased. Further, when peel strength at end of plate is under 22kgf/mm<2>, the maximum load is decreased because of ply separation at impact.

Abstract: PURPOSE:To enhance the reliability of wire bonding at a tip part of a lead by constituting a stage with a flattened surface which supports a tab and a slanting surface which supports the tip part of the lead and gradually falls down in the outside direction. CONSTITUTION:In a stage 1 which loads a lead frame 2, which fixes a semiconductor chip 4, the stage 1 is cone-shaped in structure and supports a tab 3 with a flattened surface at the central part and a lead 5 as well with a surrounding slanted surface 12.

Abstract: PURPOSE:To immediately stop an internal air conditioner in response to the stop signal of the internal air conditioner and to improve a starting feature upon request of restart with a relatively short time interval after the operation of the air conditioner is stopped. CONSTITUTION:When the last operating one of internal air conditioners 13a, 13b and 13c stops, the stop signal of the controller 21 of the internal air conditioner is transmitted to a controller 22.

IPC: G01R19/165
Filed: 1984-01-21
Abstract: PURPOSE:To prevent malfunction by absorbing a leak current in power-on operation by a current mirror circuit and a constant voltage element. CONSTITUTION:The current mirror circuit consists of transistors TR 5 and TR 13. The level of an input signal Vin supplied to a line l2 is discriminated on the basis of a predetermined threshold voltage supplied to the base of a TR 4. The level-discriminated signal is sent out of the collector of a TR 3 to operate TRs 10, 11, and 12. Then, A low-level or high-level output signal is sent out of the collector of a TR 12 according to whether the level of the input signal supplied to the line l2 is lower or higher than the threshold voltage. When a voltage VDD applied to a line l1 with a power source on rises and at 0-about 3V, a leak current is absorbed by a Zener diode ZD 1. When the voltage rises above about 3V, a constant current I1 flows out of a constant current source A1 to operate the TR 13 and the leak current is absorbed by the TR 13 through the Zener diode ZD 1.
