Patent JP-S63109023-A (JP)
Title: Manufacture of multilayer printed board
Inventor: OKUBO KAZUO
IPC: H05K3/46
Filed: 1986-10-27
Abstract: PURPOSE:To suppress resin flow and consequently manufacture a multilayer printed board, which has neither warpage nor twisting, is excellent in dimensional accuracy and has favorable heat resistance and electrical characteristics, by a method wherein the board is heated and pressurized under reduced pressure environments and, after the reduced pressure environments are relieved, the heating and pressurizing of the matter to be formed are kept on going in order to form the board. CONSTITUTION:An inner layer board, a prepreg and an outer layer copper foil are set in a vacuum forming device in order to start the heating of the board, and the evacuation of the device is started at the stage of the time W. During the period ranging from the time, when a forming pressure G is changed over to the pressurized state, to the time, when the internal temperature F of the matter to be formed reaches the maximum temperature, the vacuum H is released. The releasing of the vacuum H suppresses resin flow, and prevents the loss of resin due to the flow, the stains on a mold due to scattered resin from developing and the workability from worsening. The preferable period of the time T ranging from the time, when the changing-over to the pressurizing state is done, to the time, when the vacuum is relieved, is about 20-60min. After the relieving of the vacuum H, normal heating and pressurizing of the matter to be formed are continued for the certain period of time and, after that, cooled down and finally the pressure applied to the matter to be formed is relieved in order to obtain a multilayer printed board.

Filed: 1995-09-07
Abstract: PROBLEM TO BE SOLVED: To reduce consumption output and improve charge/discharge characteristics and at the same time miniaturize a circuit by turning on or off first to fourth switch circuits with first and second input signal lines. SOLUTION: In a charge pump circuit, each source/drain of pMOS transistors P2 and P2 and nMOS transistors N1 and N2 are connected in cascade between a high-potential side power supply line 101 and a low-potential side power supply line 102. Then, when the potential of an input signal line 103 is equal to the potential of the power supply line 102, the pMOS transistor P2 is turned on, the P1 is turned off, and a charge is accumulated in a capacitance element C1. Similarly, when the potential of an input signal line 104 is equal to that of the power supply line 101, a charge is accumulated in a capacitance element C2.  When the potential of the input signal line 103 is equal to that of the potential line 101 and when the potential of an input signal line 104 is equal to that of the power supply line 102, the capacitance elements C1 and C2 are short- circuited and the electric charge disappears, thus stabilizing the low power consumption and charge/discharge characteristics and miniaturizing a circuit scale.

Title: Combustion control device for internal combustion engine
Inventor: TOGAI KAZUHIDE
IPC: F02D21/08
Filed: 1994-10-20
Abstract: PURPOSE: To reactivate the purifying capacity of exhaust gas purifying catalyst, and control the discharge of nitrogen oxides to be low by providing an unburnt gas increasing means increasing the amount of unburnt gas exhausted to the exhaust gas purifying catalyst from an internal combustion engine. CONSTITUTION: An intake pipe 9 is connected to the intake port 2 of an internal combustion engine 1 through an intake manifold on which a fuel injection valve is mounted. An ECU 23 allows interruption to be executed by mis-firing control every time when a crank angle interlocking signal occurs, which is supplied by a crank angle sensor 18. Every time when the amount of catalyst exhaust NOx exceeds a specified threshold value, ignition for a specified cylinder is thinned at the specified period of mis-firing over a specified number of times, and unburnt gas is intermittently supplied to NOx catalyst 13a. By this constitution, NOx is sufficiently reduced from the NOx catalyst 13a so as to be removed, and the NOx absorption capacity of the NOx catalyst 13a is thereby well reactivated.  Thus as mentioned above, the purifying capacity of exhaust gas purifying catalyst can be reactivated, and the discharge of nitrogen oxides can also be controlled to be low at all times.
