IPC: H01L23/473
Filed: 1984-10-01
Abstract: PURPOSE:To produce a cooling structure with excellent radiating efficiency by a method wherein a heat conductive bar provided with a cylindrical plane with conical hole in the central part to be screwed up and down vertically and a conical axle with a conical hole and a female screw to be driven as well as a slot in the female screw direction passing through the axle center is inserted into a thermal conductive plate to be driven by a male screw. CONSTITUTION:A conical axle 9 with a female screw 8 in the central part to be driven along a conical hole is fixed to a cylinder 10 with the conical hole and a slot 6 passing through the central part leaving a little bit non cut part while a basic plane 7 is brazed. The conical axle 9 is screwed up along the cylinder 10 by means of driving a male screw 16 into a female screw 8. As soon as the cylinder 10 is fully tightened, the component in contact pressure in the radial direction expands the slot width 6 to fix the cylindrical plane of assembled body (thermal conductive bar 15) on the inner plane of a thermal conductive plate 17 by means of thrusting the former. Through these procedures, a fine gap may be set up between the basic plane 7 and the surface of all ICs to fill a jacket 30 with cooling water. In such a constitution, a cooling structure with excellent radiating efficiency insulated from water may be produced and the thermal resistance may be further reduced by means of filling the gap 14 with electric insulating and thermal conductive filler.

Title: Ink jet recording device
Inventor: SAITO ATSUSHI
IPC: B41J2/175
Filed: 1990-08-03
Abstract: PURPOSE:To decrease the separating speed of a wiper member immediately before it moves away from ink discharge faces and prevent the ink from scattering from the wiper member to avoid the peripheral contamination by providing a control means to change the rotational speed of the wiper member and the driving speed of a recording head during wiping operation. CONSTITUTION:Upon input of instructions of wiping operation, CPU drive a cap unit 10 to separate a cap member 11 from the ink discharge surface 5A of a head unit 5 and move the head unit 5 to the wiping position of a wiper member 12 at a relatively high first speed set under the instruction and, at the same time, the cap unit 10 is driven to wipe the ink discharge face 5A with the wiper member 12 held in contact therewith. When it is confirmed that a row of ink discharge openings have been wiped clean, the CPU gives a driver the instructions to set a slow second speed and the wiping is continued while decreasing the rotational speed of the head unit 5. This method can prevent the spray of the ink from scattering due to an abrupt rebounding of the wiper member 12 taking place when the wiper member 12 moves away from the ink discharge faces 5A.

Filed: 1983-11-07
Abstract: PURPOSE:To make sure the operation of an air-fuel ratio control device with a simple structure, by directly controlling the energization time intervals of a proportional solenoid valve with the use of a CPU while monitoring the current of a drive transistor upon energization. CONSTITUTION:Upon energization of a transistor 4, a voltage between both terminals of a resistor 5 is monitored by means of an AD converter circuit 6, and by changing the energization time ratio of control pulses from the CPU the averaged current of a proportional solenoid valve 3 is made coincide with a desired value. However, dispersion in the resistance of the resistor 5 and so forth, cause the averaged value to be difficult to precisely coincide with the desired value, and therefore, the time rate of rich and lean signals from an air-fuel ratio sensor 1 is monitored so that a compensation is made to the desired current value of the proportional solenoid valve 3. With this arrangement, the structure of the circuit may be simplified to reduce the number of component parts, and as well the characteristics of the control system are made stable and sure.
