Title: Semiconductor device and fabrication of the same
Inventor: SUZUKI YUJI
IPC: H01L21/28
Filed: 1992-07-20
Abstract: PURPOSE:To provide a semiconductor device with a back electrode, whose ohmic characteristic is improved, and a method of fabricating the same. CONSTITUTION:An alloy layer 21 is formed at the back, 12, of a silicon substrate 1 containing an impurity. The alloy layer 21 contains gold, an impurity X of the same type as the impurity of the substrate 1, and silicon. The alloy layer 21 improves the ohmic characteristic between a back electrode 2 and the substrate 1. A gold layer 22 prevents formation of a silicon-nickel alloy layer. A nickel layer 23 improves the wettability of the back electrode 2 with solder. As the alloy layer 21 is formed at the back 12 of the silicon substrate 1 with the gold layer 22 and nickel layer 23 stacked on the alloy layer 21 in order, a nickel-silicon alloy layer is not formed.

Title: Monitoring method for electron beam current
Inventor: USUI YOICHI
IPC: H01L21/30
Filed: 1986-09-12
Abstract: PURPOSE:To make it possible to monitor the beam current, to maintain the exposing intensity constant, and to reduce the time required for exposure operation, by radiating laser beams to an electron beam in the lateral direction, and detecting the intensity of the Thomson scattered beams. CONSTITUTION:The laser beam 10 of a laser 9 is radiated to an electron beam 1 between an aperture 4b and a lens 3c from the square direction (from the far side in the figure). The resultant Thomson scattered beams 11 are detected by a light detector 12 which is positioned in the square direction all to the thomson scattered beams 11, the electron beam 1, and the laser beam 10 (in the right direction in the figure), through a filter 13. The Thomson scattered beams 11 are radiated in all directions, but the intensity in a random direction, the intensity detected by the light detector 12, for example, is proportional to the beam current of the electron beam 1, and so the light detector 12 can monitor the beam current. Therefore, when the beam current generates a change, the exposing intensity can be maintained constant by providing a countermeasure, and moreover, the time required for the exposure operation can be reduced.

Title: Switching circuit
Inventor: YAMAGUCHI ATSUO
IPC: H03K17/04
Filed: 1982-12-08
Abstract: PURPOSE:To decrease the switching time when the switching characteristics of a high voltage level are obtained with the drive of a low voltage level, by actuating an npn transistor (TR) in an unsaturated region and at the same time suppressing the amplitude of the collector voltage. CONSTITUTION:The collector of an npn TR6 is connected directly to the base of a pnp TR9 as well as to the positive pole side of a high voltage source 2 via a resistance 8. The emitter of the TR6 is connected to a pulse source 11 via a resistance 12, and the base of the TR6 is connected directly to the positive pole side of a low voltage source 1. First, the emitter current of the TR6 of a preceding stage is intermitted by the source 11, and therefore the TR6 is switched. In accordance with switching of the TR6, the TR9 of a following stage is switched. As the TR6 works in an unsaturated region, the storage time does not exist. At the same time, the variation of the collector voltage is also reduced, and therefore the time required for change of the collector voltage is also reduced.

Abstract: PURPOSE:To securely close a path while preventing an elastic pipe from degradation by stopping pinching portions approaching excessively each other and kept away from each other by an elastic repulsion at a predetermined distance. CONSTITUTION:A path 83 in an elastic pipe 55 between pinching portions 57, 80 is closed by clamping wall portions 60, 61 and pushing said wall portion 60 toward said wall portion 61 side in the direction C against a spring 63. Further, a pinching member 58 is pushed somewhat in the direction C to form a slight gap G between an engaging surface 77 of an engaging member 64 and a surface 76 of a hole 70 in said member 58 so that the engaging portion 71 of engaging member 64 is pivoted by the force of a spring 69 in the direction E and fitted into the hole 70 in the pinching member 58. Thereafter, when the clamp of said wall portions are released, the pinching member 58 is retured in the direction D by the elastic repulsion of the elastic pipe 55 and an expansion force of the spring 63 until its movement in the direction D is blocked by the surface 77. By adjusting a nut 67a, can be closed the path 83 of the pipe 55 in stopping the pinching member 58 and the deformation of the elastic pipe 55 can be reduced as small as possible.

Title: Solar heat water heater
Inventor: IWABUCHI HIROO
IPC: F24J2/46
Filed: 1984-10-16
Abstract: PURPOSE:To furnish a solar heat water heater, in which the operation of a feed water valve is unnecessary, by a structure wherein the feed water valve, which starts to feed water only when the insolation or the daytime is detected. CONSTITUTION:A water level sensor 11 to detect the water level is connected through a controlling device 12 to a feed water valve 13. When an insolation sensor 10 detects the insolation and at the same time the water level sensor 11 detects a water level lying below the predetermined water level, the controlling device 12 opens the feed water valve 13. When evening comes and no insolation exists, the feed water valve 13 is closed. Consequently, no matter how much hot water is used, the mixing of cold water with hot water does not occur until when the insolation restores again or the following day. Immediately after the restoration of the insolation on the following day, the feed water valve is open so as to keep on feeding water until the water level sensor 11 detects the arrival of the predetermined water level. A twenty four hour timer 14 may be used instead of the insolation sensor 10.

Abstract: PURPOSE:To stably form a toner layer with a fixed layer thickness by detecting the thickness of the toner layer carried into an electrode facing part from the quantity of light reflected by the layer and controlling the magnitude of a toner layer forming bias voltage. CONSTITUTION:A photosensor 13 is disposed on a position moved by a prescribed distance X away from a position where a toner supplier 2 supplies a magnetic toner (t) to form a toner layer. The toner layer tc is irradiated with light to detect the quantity of the reflected light. A reflection density is outputted as a function of the reflected light quantity, and goes to a high level as the toner layer becomes thicker. Consequently, the reflection density is substituted for the thickness of the toner layer. An automatic voltage controller 14 controls the magnitude of a bias voltage applied to the toner supplier 2 according to data on the reflection density of the toner layer tc, which is inputted and detected by the photosensor 13. Thus, the toner layer with a fixed thickness can be stably formed all the time.
