Title: Preparation of multi-layer printed-wiring board
Inventor: YOSHIDA TOMOAKI
IPC: H05K3/46
Filed: 1987-03-30
Abstract: PURPOSE:To reduce the coefficient of dimensional change when multi-layer lamination is done, by using an inner layer core having a specific glass transition temp. and carrying out gelation and molding of a resin of a prepreg when the temp. of this inner layer is 140-180 deg.C. CONSTITUTION:An inner layer and an outer layer are laminated through a prepreg and heated and pressed. An inner layer core whose glass transition temp. (Tg) is 180 deg.C or more is used and a resin of the prepreg should gel when the temp. of the inner layer plate is 140-180 deg.C. When a resin whose gelation temp. is high is used, as the lamination temp. is at or below the gelation temp. and the decrease in the mechanical strength of the inner layer plate is small, the influence owing to these outer forces can be ignored. Then, at the third stage from the max. temp. 2 to taking out of a product through cooling, the residual stress remaining in the inner layer plate is released due to the pressure released and the shrinkage occurs. Therefore, the amt. of the dimensional change as the final multi-layer plate can be reduced by carrying out the gelation of the resin at higher temp. side (at or above 140 deg.C and at or below Tg of the inner layer core) and laminating the inner layer plate while it is being much largely thermally expanded.

Title: Semiconductor integrated circuit and data-processing apparatus
Inventor: SHINOHARA SHIGERU
IPC: G11C11/41
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To surely equalize a but line by asserting an address detection pulse before a word line selection state is changed by a change in intermediate level of an address signal. SOLUTION: When an address signal is changed, an address buffer 1 turns a complementary address signal to the same logic value for a fixed period. An address change-detecting means 20 adds the period to an assertion period of an address change detection pulse 209, thereby asserting the address change detection pulse in a transition period before the address change is settled. A state change corresponding to the address change tends to be faster at the address change-detecting means than at an address-decoding means 30 because of a relation VLT2>VLT1 wherein the VLT2 is a logic threshold voltage of the address change-detecting means and VLT1 is a logic threshold voltage of a circuit of an initial stage of the address-decoding means.

Abstract: PROBLEM TO BE SOLVED: To eliminate black smoke generation from an engine by simplifying the mechanism of an EGR control valve, establishing a high precision control, and assuring quick response closing of the control valve when a vehicle is in steep deceleration. SOLUTION: An atmospheric pressure chamber 9, diaphragm 10, diaphragm actuating pressure chamber 8, and motor 22 are arranged in the sequence as named from the side with an EGR reflex path 2 to the lifting direction of a valve element 5. One end 5B of the shaft of the valve element 5 is connected with the diaphragm 10. The output shaft 13 of the motor 22 makes linear motion by means of a motion converting part 40 and remains out of coupling with a spindle part 5A the value element and the diaphragm 10. When the output shaft 13 makes linear motion with the drive of the motor 22, the valve element 5 makes a follow-up motion after the output shaft 13 in association with the motion of the diaphragm 10 caused by a negative pressure. At steep deceleration of the vehicle, the pressure chamber 8 undergoes a quick change- over from the negative pressure to the atmospheric, and the diaphragm 10 separates from the output shaft 13 with the force of a spring 11, and the valve element 5 closes fully the exhaust gas reflex path 2 at a high speed.
