Title: Ink jet recording apparatus
Inventor: HORIIE MASANORI
IPC: B41J2/175
Filed: 1983-05-31
Abstract: PURPOSE:To prevent the dripping of ink and to expedite the rise of formation of ink droplets at the time when the ink jet is started, by driving an ink pressurizing pump while the jet of ink droplets from an ink jet head is left OFF during a prescribed time at the initial stage of ON-operation of a power source. CONSTITUTION:In relation to the drive of valves, the drive of a pump is started earlier for a prescribed time than the jet of ink after a power source is turned ON. This time interval is set to be enough so that the ink pressure inside an accumulator 5 and an ink supply pipeline made of elastic vinyl tube which are provided between a pump 4 and a first valve 6 can rise from a pressure of 0kg/cm<2> to a jetting pressure in the condition that the first valve 6 is OFF. According to this setting, the dripping of ink can be prevented and the formation of ink droplets can be performed normally when the jet of ink is turned ON, even when the pressure of ink between the pump 4 and the first valve 6 lowers to 0kg/cm<2> before ink jetting.

Abstract: PURPOSE:To control the quantity of light of an emission source and to make the quantity of reflecting light constant by correcting the output signals of the second detector which detects the quantity of light reflecting from an information recording medium and of the first detector in accordance with the said quantity of reflecting light. CONSTITUTION:A signal detected by respective sensors of the optical detector 8 is IV-converted by a pre-amplifier 18, added by an adder 180, and is outputted as an HF signal. This HF signal is made subjected to full wave rectification by the HF level detector 190 and diodes 191 and 192 of an AGC circuit 19, and is converted to an HFL signal of an amplitude correspondent to the quantity of light reflecting from a disk 4. This signal HFL is inputted to a comparator 193, and is compared with a reference voltage Vc generated by a reference voltage generating circuit 194 in order to control its quantity to be constant; a supply-correct I2 for IV converter 10 is so controlled as to lower the said quantity if HFL>Vc but to rise if HFL<Vc. Consequently, the input signal to the pre-amplifier 18 is maintained constant even if the reflectance of the disk 4 and/or optical elements of the optical pickup have variance.

Title: Semiconductor device
Inventor: SHIBATA KAZUTAKA
IPC: H01L23/36
Filed: 1990-04-12
Abstract: PURPOSE:To make the coupling between a semiconductor device and resin stronger by making a part of the resin to enter a slit formed between a fin fitting hole and chip bonding area so that the part of the resin can crop out in the same plane as the rear surface of the chip bonding area. CONSTITUTION:A slit 7 is formed between the chip bonding area 4 and fitting hole 6 of a fin 1 and a resin 3 put on the surface of the fin 1 is made to enter the slit 7 so that the resin 3 can crop out in the same plane as the rear surface of the area 4. Accordingly, even when an external force is forcibly applied to the fin 1 at the time of tightening a screw, etc., the stress produced in the fin due to the external force does not affect a molded resin section near the chip bonding area, because the stress is absorbed and relieved by the slit, and coming off of the resin hardly takes place. Therefore, the coupling between the fin and resin becomes stronger.

IPC: H05K7/14
Filed: 1988-04-20
Abstract: PURPOSE:To prevent a stress from generating on a board by inserting and removing force at the time of wiring a connector and to reduce the number of clamping screws by providing a metal box having a pair or upper and lower pawls for holding the board at two corners. CONSTITUTION:One side end face of a printed board 2 is slid between a pair of upper and lower pawls 4 and 5 of an attaching unit 1 to be held, and the other end face is then clamped with clamping screws 7. Thus, in case of wiring, even if stresses are generated in the board 2 at the time of inserting and removing a terminal of a connector 8, a control relay 9, they are protected by the pawls 4, 5 as a pair of upper and lower pawls to prevent the board from cracking and the foil from peeling. Since the method of clamping with the pair of upper and lower pawls may need small engaging margins with the board, a component on the board can be disposed in a wide range, and the number of the components to be placed thereon can be increased.
