Title: Power module
Inventor: KANDA MITSUHIKO
IPC: H01L25/18
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To realize prevention of malfunction of a power module due to elements and an interference between internal circuits and the effect of reduction in a conduction and radiation noise in the power module, by a method wherein the power module is provided with a second insulating layer which is interposed between metal base plates for separating electrically fellow regions formed with first circuit patterns from each other. SOLUTION: A metal base plate 3, which is the constituent element of a metal substrate 2 with power elements 6 mounted on the upper part thereof, is mounted in the interior of a power module 1. The base plate 3 is split in each region, on which each power element 6 and first circuit patterns 5, which are connected with the element 6, are constituted, and a second insulating layer 8 is provided between the adjacent base plates 3, whereby the split base plates 3 are insulated from each other. Consequently, a stray capacitance is generated between the base plates 3 under the regions and noise results in being propagated via this stray capacitance.  As a result, a coupling of the noises between the elements 6 results in being inhibited, and malfunction of a power module due to this coupling of the noises and a conduction and the propagation of radiation noise in the power module can be reduced lower.

Title: Magnetic recording and reproducing device
Inventor: TANAKA AKIRA
IPC: H04N5/937
Filed: 1986-07-11
Abstract: PURPOSE:To obtain the reproducing of the still picture of a good quality by utilizing a picture memory circuit and a skew jump correction circuit in a device in which a pair of magnetic heads with different azimuthes is used. CONSTITUTION:At the time of reproducing the still picture, the reproduced output of one magnetic head, the azimuth of which coincides with a recording track, is stored in a picture memory circuit 23. A change-over switch 7 outputs the reproduced picture of the picture memory circuit 23, instead of the reproduced output of the other magnetic head, the azimuth which does not coincide with the recording track. The skew jump correction circuit 25, in the case that an odd sum is caused in the numbers of a horizontal synchronizing signal contained in a reproduced output obtained per one time of the scanning of the magnetic head, corrects the skew jump by means of stopping or extending the reading-out of the picture memory circuit 23 for a period corresponding to the odd sum. In this way, the still picture of a good quality and without the noise can be reproduced.

Abstract: PURPOSE:To facilitate forming a uniform potential barrier region beneath a light detection part by a method wherein an impurity of the same conductive type is implanted into a substrate of one conductive type beforehand and an epitaxial layer of the opposite conductive type is grown. CONSTITUTION:A high concentration N-type region 3 is formed in a predetermined region of an N-type substrate 5 in order to form a P<-> type region 2 beneath a light detection part only by compensating with a P-type epitaxial layer 4 and, when the epitaxial layer 4 is made to grow, the potential barrier region beneath the light detection part is given P<-> conductive type by the diffusion from the high concentration N-type region 3. Further, an N<+> type region 1 which is to be the light detection part is formed above the P<-> type region 2 to compose a vertical type overflow drain and a solid-state image pickup device which has a cross sectional structure of the light detection part - the P-type region (epitaxial layer) - the N-type substrate is obtained. With this constitution, as the potential barrier region beneath the light detection part is composed of the epitaxial layer with uniform impurity concentration, the uniform potential barrier region can be obtained. Therefore, characteristics defects such as uneven sensitivity caused by variation of blooming suppression effect can be avoided.

Title: Power source
Inventor: KUROKAWA HIROSHI
IPC: H02M3/28
Filed: 1983-09-06
Abstract: PURPOSE:To reduce the quantity of heat of a stabilized resistor by connecting a switch in series with the resistor, and controlling ON or OFF of the switch in response to the operating state of a load. CONSTITUTION:When a machine of a load side is at a standby time, an external control signal becomes ''0'', a switch 56 is turned OFF, and a stabilized resistor 55 is released. On the other hand, while the machine of the load side is operating, the external control signal becomes ''1'', the switch 56 becomes ON, and the resistor 55 is connected. Thus, since the resistor 55 is released even at the machine standby time, the resistor 55 does not generate heat, thereby preventing the thermal deterioration of circuit component parts such as semiconductors and the like in a power source.

Abstract: PURPOSE:To prevent the breakage of a rotor due to the generation of reverse thrust on starting and on stop by detecting the position in the axial direction of a rotor and controlling the hydraulic pressure supplied in to the chamber on one side of a cylinder for shifting a rotor shaft in the axial direction. CONSTITUTION:When a rotor 1 shifts in the reverse thrust direction, the gap DELTAS between a detection collar 15 installed at the edge part of a rotor shaft 1b and a gap detector 16 varies, and the variation quantity is detected by the gap detector 16.
