Title: Electrical hot water heater
Inventor: ARIHARA MASAKATSU
IPC: F24H1/10
Filed: 1991-08-30
Abstract: PURPOSE:To cause heated water to be always present in a heat exchanger and to prevent any over-heating damage caused by an idling electrical discharging by a method wherein each of water feeding passage and a water discharging passage of an instantaneous hot water heater is disposed at an upper part of a heat exchanger. CONSTITUTION:Each of the first, second and third spacings 4 and 4 and 10 is formed by an inner cylindrical member 2, an intermediate cylindrical member 2 and an outer cylindrical member 3 arranged concentrically. Heated water 12a flows in the third spacing 10 between the intermediate cylindrical member 2 and the outer cylindrical member 3 and the first spacing within the inner cylindrical member and at the same time a voltage is applied to the second spacing 4 between the inner cylindrical member and the intermediate cylindrical member 2 so as to form an arc plasma 11. Temperature of the heater water 12a flowing in the first and the third spacings 10 is increased by the generated heat. In this case, a water feeding passage 16a and a discharging water passage 17a for the heated water 12a are arranged at an upper part above a heat exchanger including the arc plasma heat generating part. With such an arrangement, the heated water is always present at the heat exchanging part and occurrence of the excessive heating caused by an idling electrical discharge can be prevented.

Title: Semiconductor device
Inventor: MATSUSHIMA MASAKAZU
IPC: H01L21/52
Filed: 1983-11-22
Abstract: PURPOSE:To realize a structure excellent in productivity and designability by a method wherein element mounting portions are removed, leads are wired to reach the inside, and semiconductor elements are installed bridging each one of the leads. CONSTITUTION:A lead frame is not provided with locations for mounting semiconductor elements and each one of the leads 2 is formed to run as far as the inside of the lead frame. An semiconductor element 3 is mounted bridging the internal segment 2', located inside the mold boundary 7, of each of the leads 2. Accordingly, the size of a mountable semiconductor will not be limited due to the size of a semiconductor element installing location as in the conventional technique. As the result, packages of the same type can use a unified lead frame material, which in turn reduces the manufacturing cost and increases efficiency. The lack of semiconductor element mounting locations greatly facilitates the designing of semiconductor elements and base ribbon. With the supporting leads for semiconductor element mounting locations being eliminated that are needed in the conventional method, there is less infiltration of water through the interface between resin and metal, which improves the humidity-resisting feature of the device and the element mounting locations can be free of plating with metal.

Abstract: PROBLEM TO BE SOLVED: To realize high density integration such as multipins and narrow pitchs at a low manufacturing cost and with high efficiency, by arranging a plurality of terminals connected with a semiconductor chip terminals in such a manner that intervals between neighboring terminals are made equal. SOLUTION: Solder bumps (HB) 15 are arranged as I/O terminals of a BGA on the bottom surface of a PCB board in such a manner that intervals between the neighboring HB's 15 are made equal.

As a result, density per unit area of the HB's 15 is increased as compared with conventional grid arrangement shown by a two-dod chain line, and a semiconductor device coping with high density integration such as multipins and narrow pitchs can be realized at a low manufacturing cost and with high efficiency.

Title: Photoelectromotive force device
Inventor: FUKATSU TAKEO
IPC: H01L31/06
Filed: 1984-10-19
Abstract: PURPOSE:To improve structural strain at an interface between neighboring amorphous semiconductors and to improve the film quantity of an amorphous SiGe layer, by increasing the width of an optical forbidden band as the I-type amorphous SiGe layer of a photoelectromotive force element approaches the light inputting side. CONSTITUTION:Light is inputted in an amorphous element through a light transmitting insulating substrate 1 and a transparent conducting film 2. Generated electrons and holes are collected in an electrode film 12 and the transparent conducting film 2. P type layers 3, 6 and 9 are composed of amorphous silicon carbide. Of I-type layers, the I-type layers 4 and 7, which are close to the light inputting surface, are composed of amorphous silicon. An I-type layer 10, which is the farthest, is composed of amorphous SiGe. N type layers 5, 8 and 11 are composed of amorphous silicon, in which phosphorus is doped. The ratio of Ge to Si in the I-type layer 10 is made gradually large, from the side of the neighboring P type layer 9 toward the side of the N type layer 11. The width of the optical forbidden and (b) of the I-type layer 10 is made gradually large as the side of the P type layer, i.e., the incident surface of the light is being approached. Thus the difference in energy levels of a valence band (c) and a conduction band (a) in the vicinity of the boundary with the P type layer 9 is alleviated and the output characteristics of the photoelectromotive force element can be improved to a large extent.
