Title: Heating or cooling device
Inventor: KANNOU SHINICHI
IPC: F24F1/00
Filed: 1988-10-26
Abstract: PURPOSE:To improve a convection flow heating capability with hot air sent from an atmosphere passage into a room during heating operation by a method wherein the atmosphere passage is arranged between a heat radiation wall and a heat source means and then heat is transmitted from the heat source means to the heat radiation wall by thermal conducting member. CONSTITUTION:In case of forming a heat radiation wall A and a plate-like heat transmitting member C, several hardwares 4 having U-shaped section are arranged side-by-side while their both end surfaces being substantially in flush to each other and the adjoining ones being adjacent to each other. The heat radiation wall A is formed at both ends 4a and 4b of the hardwares 4 and the plate-like heat transmitting member C is formed at the central part 4c. A tube B of a heat source means is bent and formed in a zig-zag form, by a straight pipe 5a passed through and contacted with all the plate-like heat conducting members C while being spaced apart from the heat radiating wall A and a bent pipe portion 56 for connecting the straight pipes 5a to each other. During heating operation, interior air is sucked into a downstream end of the atmosphere flow passage 7 and heated by the heat source means B; thereafter, the air is returned from its upstream end back into a room.

Title: Semiconductor device
Inventor: NIIMI TOSHIO
IPC: H01L27/08
Filed: 1985-12-04
Abstract: PURPOSE:To reduce a surface recombination current and to stabilize the electric characteristics of a transistor, by forming at least one of the emitter layer and the collector layer of the lateral PNP transistor not on the surface of a semiconductor but on the bottom surfaces of shallow grooves. CONSTITUTION:An emitter layer 5 and a collector layer 5' of a lateral PNP transistor are provided on the bottom surfaces of shallow grooves 7 and 7'. An interface between an insulating material and the surface of a semiconductor is a cause of decreasing the current gain of the transistor. In order to prevent said decrease, it is necessary to avoid said interface and to operate the transistor. Surface recombination at the interface of the insulator 4 is markedly decreased. Holes, which are injected from the emitter 5 of the lateral PNP transistor, reach the collector 5' through the inside of the semiconductor. During this period, the recombination occurs in the semiconductor and does not depend on the size of the recombination center of the interface 4'. Therefore, approximately constant gain can be imparted, highly reliable electric characteristics can be imparted and erroneous operations of circuits can be avoided.

IPC: H01L21/60
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To improve the required dimensional stability, heat resistance, moisture resistance, chemical resistance and mechanical characteristics of a film carrier for TAB by employing a polyethylene naphthalate film, the coefficient of thermal expansion of which is within a specified range. SOLUTION: A film carrier for TAB is used of which the coefficient of thermal expansion (αT) on the film plane is 9×10<-6> / deg.C or above and 20×10<-6> / deg.C or below, and the absolute value of the difference between the maximum coefficient of thermal expansion αTmax and minimum coefficient of thermal expansion αTmin of which is 6×10<-6> / deg.C or below. A TAB carrier film material is bonded to copper foil for use. For the reason, its coefficient of thermal expansion must be close to that of copper. If the coefficient of thermal expansion (αT) of a carrier film exceeds 20×10<-6> / deg.C, the carrier film, when bonded to the copper foil, is curled owing to a difference in the coefficient of thermal expansion with the copper foil, and is unusable.

Title: Magnetic disk device
Inventor: MATSUMOTO TOSHIO
IPC: G11B21/21
Filed: 1988-10-28
Abstract: PURPOSE:To obtain the satisfactory overwrite characteristics with a small spacing loss even with a magnetic head set at the outer circumferential side of a magnetic disk by giving the floating characteristics to this magnetic head so as to secure the smaller floating height than a magnetic head set at the inner circumferential side against the same peripheral speed of the disk. CONSTITUTION:The floating surface width Wb of a magnetic head 12 set at the outer circumferential side of a magnetic disk 1 is set smaller than the floating surface width Wa of a magnetic head 11 set at the inner circumferential side. As a result, the floating height of the head 12 is smaller than that of the head 11 against the same peripheral speed of the disk 1. Therefore the floating height H2 of the head 12 is smaller than the floating height H2' obtained with use of a magnetic head having the same floating surface width as the head 11. While the floating height H1 of the head 11 is larger than the floating height H1' obtained with use of a magnetic head having the same floating surface width of the head 11. Thus the satisfactory overwrite characteristics can be obtained with a small spacing loss even with a magnetic head set at the outer circumferential side of a magnetic disk.
