Abstract: PURPOSE:To suppress occurrence of voids due to entrapments of air and so on, by pouring a resin into each cavity of the second row and after through a path being connected with a cavity of the preceding row and setting a gate and a connecting path on a diagonal line of each cavity. CONSTITUTION:A resin poured into a cavity 23 in the front row is applied into the cavity along a diagonal line, brought out in a connecting path 28, and poured into a cavity 23 is the second row. The resin poured into a cavity 23 in the second row is applied into the cavity 23 along a diagonal line, and brought out from a connecting path 28 being set on a diagonal position of a gate 27. The resin reaching the connecting path 28 is poured into a cavity 23 in the third row 23 from the gate 27, and applied along a diagonal line in the same manner as the preceding row. Transmission efficiency of the resin pouring pressure becomes thereby very good. Moreover, as entrapment of air in the resin filling process is suppressed, occurrence of voids in a package 13 is prevented.

IPC: G06K17/00
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To effectively eliminate noise caused by a flaw, etc., on a card and to accurately read out a punch hole or a magnetic bar by processing a read-out output signal of a magnetic head with a band pass filter for passing only a prescribed frequency component of the punch hole or the magnetic bar and reading the processed signal. SOLUTION: A signal generated at the time of moving the card C in contact with the magnetic head H is amplified by an amplifier circuit 1, and is then processed by the band pass filters (BPFs) 2a and 2b. The BPF 2a is used for detecting the punch hole P, while the other BPF 2b is used for detecting the magnetic bar. Then, a signal corresponding to the punch hole P out of output waveforms of the magnetic head H can be passed through the BPF 2a, but the signal corresponding to a flaw is cut off not to be outputted to a processing circuit 3a because of its frequency higher than the punch hole P. A signal corresponding to the magnetic bar can be passed through the other BPF 2b, but the signal corresponding to a flaw is subjected to cut-off processing because of its high frequency.

IPC: G06F3/02
Filed: 1987-12-08
Abstract: PURPOSE:To prevent a malfunction by encoding a custom code to discriminate devices with the use of a CMI code and transmitting it. CONSTITUTION:When an operation is started from a start A, '11' of the CMI code corresponds to a first original signal '1', and when the operation is started from a start B, '00' of the CMI code corresponds to the first signal '1'. Consequently, a fact is used that even when an original signal column to be transferred is the same, two types of a CMI code columns exist because of the difference of starting positions. That is, when the signal having a starting bit 14, a data bit 16 of 8 bits or a stopping bit 17 is added by a custom code 15 of 4 bits, the following is attained. When the code column of an upper stage is CMI-coded by a code rule starting from the start A, the CMI code column of a middle stage is generated, and when CMI-coded by the rule starting from the start B, that of a lower stage is generated, respectively, and since the custom code is at 4 bits, and the alternating rule of the CMI code uses a position having only 2<4>, namely, 16 types of combinations, the 32 types of combinations can exist.

Title: Shift control device for continuously variable transmission
Inventor: SUZUKI YUTAKA
IPC: F16H61/04
Filed: 1989-11-29
Abstract: PURPOSE:To perform running on a downward slope at a given speed by effecting control so that a car speed is adjusted to a given value based on a current car speed when a throttle is fully closed. CONSTITUTION:For example, when a driver fully closes a throttle during running on a downward slope, the full closing is detected by a throttle full closing detecting device A. A target car speed setting means B controls a change gear ratio through a change gear ratio command means D so that during continuance of the full closing state of the throttle, running is effected at a car speed set as a function of a time from a car speed available when a throttle stored in a car speed memory means C is brought into a full closing state. Namely, when inclination of a downward slope is high, a change gear ratio is increased to increase an engine brake effect, and when the inclination is low, the change gear ratio is reduced. This constitution realizes running at a given car speed on a downward slope, for example, a car speed changed according to the lapse of a time or a specified car speed.

Abstract: PURPOSE: To surely prevent tobacco smoke from flowing into zones other than smoking zones in the setting of at least one as smoking zone among a plurality of zones by controlling the amount of air blown so that the internal room pressure in the smoking zones is lower than that in the circum ference thereof. CONSTITUTION: A second zone 14b is set as smoking zone when demand amount of air for first to third zones 14a-14c are all 1,000. In this case, 800 in the amount of air obtained by subtracting 200 as specified amount of air from 1,000 in the demand amount of air is set as target amount of air to be supplied to the smoking zone 14b. At this point, the same amount of air is discharged from exhaust ports 34 associated with the blowing of air conditioned with an air supply fan 30. But in the second zone 14b, the internal room temperature becomes lower relatively than the internal room temperatures of te other zones 14a and 14c, hence causing a part of air in the zones 14a and 14c to flows into the smoking zone. In other, words, the tobacco smoke from the smoking zone is prevented from flowing into the other zones.

Title: Automatic focus pull-in device
Inventor: HONGO KIMITOSHI
IPC: G11B7/085
Filed: 1987-12-07
Abstract: PURPOSE:To attain stable focus servo pull-in operation within a short period by impressing positive/negative switching pulse signal from a pulse generator at the time of pull-in operation and instantaneously raising and decelerating an actuator. CONSTITUTION:A positive/negative switching pulse voltage having a level not influenced by static frictional force or viscosity is generated from the pulse generator 14 to raise the actuator 9 at the time of drawing a focus into a focus servo system. Consequently, the actuator 9 is instantaneously driven and an objective lens is moved. At a moment when a relative speed between a focused point and a medium face is reduced, the servo system is closed. When the face of a disk is oscillated, a pulse voltage is adjusted so that a relative speed between the maximum speed of face oscillation and a focused point moving speed goes less than a pull-in limit speed. Consequently, stable focus servo pull-in operation can be executed within a short period.
