Title: Semiconductor device
Inventor: FUJITA YOSHIRO
IPC: H01L23/31
Filed: 1992-04-27
Abstract: PURPOSE:To prevent Al corrosion, exfoliation of die.pad interface, and reflow crack. CONSTITUTION:Since a die.pad 2, a die.pad interface 3, and a semiconductor chip 1 are coated with a high moisture resistant, high heat resistant organic material layer 5 having low coefficient of thermal expansion and another organic material layer 6 where a hygroscopic, high heat resistant polymer gel having low coefficient of thermal expansion is filled with fused silica, moisture permeated into a sealing resin bulk 4 is absorbed by the organic material layer 6. A part of the moisture permeates through the layer 6 but it is blocked by the layer 5 from reaching the semiconductor chip 1, the die.pad 2, or the die.pad interface 3. Furthermore, skin effect of polymer gel in the layer 6 prevents leakage of the moisture 10 to the outside while the layer 6 absorbs thermal stress which causes cracking at the time of packaging and influence of thermal stress due to vaporization 11 of the moisture 10 is lessened.

Filed: 1986-05-10
Abstract: PURPOSE:To prevent not only the damage to a flange companion but also the generation of noise and heat from a coupling part, by providing a drive shaft positively and reversely rotating an automatic coupling joint with a motor. CONSTITUTION:When the positioning of a carrier differential A is finished, a casing D is clamped certainly. Next, a drive shaft 1 is rotated at a low speed and a drive pawl 8 is rotated at a low speed through first and second rising/ falling stands 2, 5 and, at the same time, a shift fork 10 is revolved upwardly at a low speed. Whereupon, the rising/falling stand 2 begins to rise while rotated at a low speed by the elastic force of a balance spring 3 with the upward revolution of the fork 10 and, with this operation, the pawl 8 fixed to the rising/falling stand 5 also rises while rotating at a low speed. By this rising operation, the leading end of the pawl 8 is elastically contacted with the inner periphery of a flange companion C and subsequently engaged with the recessed part E provided to the inner periphery of the companion C by the revolving motion of the pawl 8 and the elastic force of a coupling spring 6.

Abstract: PURPOSE:To provide a thermally-actuated switch which facilitates operating temperature calibration work. CONSTITUTION:A thermally-actuated switch 61 is constituted into a closed container, wherein a thermally-actuated plate 73 having movable contacts 74A, 74B is connected and fixed via a thermally-actuated plate support 71. Fixed contact supports 67A, 67B in which fixed contacts 68A, 68B are welded at one ends thereof are fixed to conductive terminal pins 65A, 65B at closed container interior sides thereof and provided with biased force for pressing a spacer 69 to a metal plate 64. The fixed contacts 68A, 68B, after being welded to the fixed contact supports 67A, 67B, are subjected to plastic deformation into specified height and specified surface shapes. Accordingly, height of the fixed contacts in respective products becomes uniform and contact pressure between contacts before operating temperature calibration thereby becomes uniform so as to facilitate temperature calibration work. Since positional accuracy depends on thickness accuracy of the spacer 69, accuracy higher than ordinary fitting accuracy can be obtained.

Filed: 1983-06-17
Abstract: PURPOSE:To enable a stable operation in a wide range of an operating condition, by determining the pressure, which acts to the back of a rotating scroll, in terms of suction pressure and discharge pressure. CONSTITUTION:The pressure equalizing hole 101f of a rotating scroll 1 is provided in a position corresponding to the winding angle lambda of a lap 1b, which is defined as lambdad>lambda>d-2pi where lambdad denotes such winding angle of the lap as to form a minimum-volume space. The pressure for the winding angle lambda-lambdad is determined in terms of discharge pressure and the pressure for the winding angle lambdad-(lambda+2pi) is determined in terms of suction pressure, because of lambda<lambdad. When the force acting to separate the rotating scroll 1 from a fixed scroll 2 has increased due to the rise in the discharge pressure, the pressure of the chamber on the back of the rotating scroll increases along with the rise in the discharge pressure so that the scrolls 1, 2 are not separated from each other.

IPC: B29C55/00
Filed: 1978-09-01
Abstract: PURPOSE: To form an excellent indented pattern and also to eliminate blister, etc., from a base material by improving exfoliation from an unhardened resin in such a manner that a rigid pattern-drawn surface is formed by using a special ink, after completion of thermal pressing formation, it is cooled once under the pressured condition, and then, it is again thermally pressed.  
     CONSTITUTION: By using an ink containing a vehicle resin having capability of exfoliating the impregnated thermal hardening resin and hardening inhibitor to control the thermal hardening resin, a pattern 2 is drawn on a decorating paper 1 and then it is dried and solidified. This is impregnated with a thermal hardening resin liquid and dried to form an unhardened film 3. This resin-impregnated paper is piled on a base material 4 with the pattern-bearing side 2 on the top and thermally pressed after piling a forming plate 5 upon it so that only resin 6 of non-pattern section is hardened. And then, it is cooled off once under the pressured condition and again thermally pressed. Thenceafter, the forming plate 5 is pulled off to remove unhardened resin section on the pattern 2, so that an objective projected-and- indented pattern is formed.  
     EFFECT: Thus formed pattern excels in wear-resisting and solvent-resisting capabilities.

Abstract: PURPOSE:To mutually utilize any computer in the same environment from other computers by applying the operation start procedure automatically to a computer having information necessary for the operation even when the operation start procedure is applied from any computer. CONSTITUTION:When a user inputs its user name and a pass word, the pass word is compared with an enciphered pass word registered in advance in the operation start information file F and when they are coincident, the environment required for the operation of a demanding computer 4A is extracted from the operation start information file F by an environment extraction section 12. In this case, when the extracted environment exists in the demanding computer 4A, the environment required for the operation is generated by an environment setting section 13 to allow the use of the demanding computer 4A. Thus, since the operation start procedure is applied automatically to the computer having the environment required for the operation even with the operation start procedure from any computer, the other computer is utilized smoothly.

IPC: H04B1/40
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To make the size small and to reduce the power consumption. SOLUTION: The circuit 12 has 1st and 2nd local oscillation sections 13, 14, a 1/M frequency divider circuit 15 and a 1/N frequency divider circuit 16. The 1st local oscillation section 13 generates a 1st local oscillation signal. In a transmitter side, the signal is mixed to a carrier signal modulated by a base band signal and a transmission frequency signal is generated. At a receiver side, the 1st local oscillation signal is mixed with a reception frequency signal and the reception frequency signal is frequency-converted into a 1st IF signal.  The 2nd local oscillator section 14 generates a 2nd local oscillation signal, at the transmitter side, the signal is subject to 1/M frequency division by the 1/M frequency divider circuit 15 and the result is used as the carrier signal, and at the receiver side, the signal is subject to 1/N frequency division by the 1/N frequency divider circuit 16 and mixed in the 1st IF signal and a 2nd IF signal is obtained. Information such as voice and data is obtained by demodulating the 2nd IF signal. Since three frequencies fL1, fL2, fL3 are obtained by the two local oscillator sections 13, 14, the circuit is made small.
