Grooves 13a, 13b having depth of half or more of plate thickness are shaped to the surfaces and rears of each of the radiator plates 2, and arranged so as to be mutually crossed at right angles, and communicating holes 14 communicated with the grooves 13a, 13b are formed at crossing intersections. Respective groove 13a, 13b of adjacent opposed surfaces is laminated so as to be mutually crossed at right angles. Accordingly, thermal resistance at the time of heat transfer and heat dissipation can be inhibited without scaling-up.

Title: Valve timing adjusting device of internal combustion engine
Inventor: MORIYA YOSHITO
IPC: B60W10/06
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To start an internal combustion engine at a proper intake valve closing timing. SOLUTION: A valve timing adjusting device 10 changes the opening and closing timings of an air intake valve by adjusting a hydraulic pressure to a spark-advance chamber and a spark-delay chamber which are formed with a vane 29 and a housing 28 so as to advance or delay the vane 29. The vane 29 is fixed at that position by inserting a lock pin 43 closely into a locking hole 49A at the most advanced position and a locking hole at the most delayed position. Also an engine is stopped so that the vane 29 is stopped at the middle position. To start the engine, when the cooling water temperature is low, a crank shaft is rotated reversely by a specified angle so as to fix the vane 29 to the most advanced position before starting. When the temperature is high, the engine is cranked so as to fix the vane 29 to the most delayed position before starting.  If the engine is started at the most advanced position, the starting at low temperature becomes easier because a compression ratio becomes high, and if the engine is started at the most delayed position, vibration caused when the engine is started at high temperatures can be reduced because the compression ratio becomes low.

IPC: H01L25/18
Filed: 1992-03-05
Abstract: PURPOSE:To reduce by half the mounting area, by installing two semiconductor devices on one metal substrate. CONSTITUTION:A P channel MOSFET chip 11 is installed on one face of a mounting part 2 of a lead frame acting as a heat dissipation substrate by a die bonding.

A source pad 3 of both the chips 11 and 12 is connected to external lead parts 51 and 53 by a bonding of an Al wire 6. A gate pad 4 is connected to an external lead part 52 by the bonding of the Al wire 6 on both faces. By securing semiconductor devices on both faces of the heat dissipation substrate, the mounting area with a complementary construction can be reduced by half.

Title: Leak detector
Inventor: YAMADA IZUMI
IPC: G01M3/24
Filed: 1987-03-04
Abstract: PURPOSE:To realize high sensitivity by deciding a leak even when the variation width of a sound exceeds a normal value. CONSTITUTION:A microphone 3 is provided nearby a high-temperature, high- pressure water transporting pipe 1 in a power generation plant. The output of the microphone 3 is inputted to an acoustic transducer 31 arranged outside a heat insulating material 2. A leak discriminator 32 decides a leak in the transporting pipe 1 when the output of the transducer 31 rises above a set level. A variation component extractor 33 detects the intermittent sensitivity deterioration of the microphone 3 and outputs it to the leak decision device 32. The discriminator 32 decides a leak in response to the output of the extractor 33. Then even if mist produced owing to a leak in the pipe 1 lowers the sensitivity of the microphone 3 intermittently, that is decided as a leak. Consequently, the leak can be detected even when environmental noises are large.

IPC: H01L21/302
Filed: 1980-04-11
Abstract: PURPOSE:To prevent the Si substrate in the element forming region from being damaged, by performing the plasma etching of the wiring polycrystalline Si after protecting the Si3N4 used to form an element separating oxide film with SiO2. CONSTITUTION:On a P type Si substrate 1, an SiO2 film 11 is formed and thereon, a mask of double-layer structure comprising Si3N4 12 and SiO2 16 is formed. Then, a thick SiO2 13 is formed by a heat treatment and coated with a doped polycrystalline Si 14. A resist mask is applied, and the polycrystalline Si 14 is plasma-etched to form a wiring 14A on the element separating layer. Thereby, being protected by the SiO2 16, the Si3N4 12 is kept from the plasma etching. Then, SiO2 15 is formed as an interlayer insulating film. Thereafter, the whole except for the element forming region is covered with a resist mask and successively etched until the substrate surface 17 is exposed, and an FET, for example, is formed. Because the FET forming surface has not been damaged, a highly reliable device, which has stable characteristics, can be obtained.

Title: Alternating current generator for vehicle
Inventor: UMEDA ATSUSHI
IPC: H02K9/06
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To increase the output along with reducing noise, by supplying a cooling wind having a larger quantity or faster velocity, to a first group of coil ends formed at one end area of a stator core, than a second group of coil ends provided at the other end area. SOLUTION: In the end area of the disk 72 of a Randel type pole core 7, a mixed flow fan 11 and a centrifugal fan 12 are provided for cooling. Here, both the projection area and the outer diameter of the blades of the mixed flow fan 11 are set smaller than those of the blades of the centrifugal fan 12. At the time of operation, a group of coil ends 31d is cooled by the mixed flow fan 11, and a group of coil ends 31c is cooled by the centrifugal fan 12. And the quantity of a cooling wind supplied by the mixed flow fan 11 is smaller than that of a cooling wind supplied by the centrifugal fan 12. Consequently, it becomes possible to reduce the interference sound of the group 31d of coil ends.  Besides, it is possible to perform cooling efficiently even by a smaller amount of cooling wind, since the group 31d of coil ends is on the side of a pulley 20, and an ambient air temperature is low.

Title: Binding method for ceramic superconducting material
Inventor: KOMATSU WATARU
IPC: H01B12/02
Filed: 1990-02-28
Abstract: PURPOSE:To accomplish the title mutual firm binding of a pair of superconducting materials without impairing critical current density by making their ends close to each other or bringing the ends into mutual contact and by deposition, on the boundary area, of fine particles of the same composition as that of said materials produced by a vapor phase process followed by treatment under heating. CONSTITUTION:Firstly, a pair of superconducting materials is arranged with their ends made close to each other or brought into mutual contact. Second, fine particles of composition same in the metallic component as said superconductor produced by a vapor phase process are put to on-line deposition on the boundary area. Thence, the fine particles thus deposited are subjected to treatment under heating to accomplish the objective mutual binding of said pair of ceramic superconducting materials. In the present method, handling of the powdery fine particles can be omitted, and productivity can be improved by continuous hot treatment of the fine particles deposited and carrying out sintering; furthermore, since the fine particles produced by the vapor phase process are those of submicron order size with high surface activity, the particles deposited can be sintered at relatively low temperatures, also resulting in firm binding to the interfaces of said materials.
