Title: Manufacture of semiconductor device
Inventor: ONO YOSHIKAZU
IPC: H01L21/26
Filed: 1987-03-25
Abstract: PURPOSE:To increase a concentration of boron and to prevent an excessive spread of an impurity layer by a method wherein a diffusion process is executed by using a lamp annealing system in a process to manufacture a semiconductor device where a boron impurity layer is formed inside a silicon substrate. CONSTITUTION:A diffusion process of a boron compound 13 formed on a silicon substrate 11 is executed by using a lamp annealing system. The lamp annealing system heats only the surface of the silicon substrate 11 intensively while the surface of the silicon substrate 11 is irradiated with the light. Accordingly, the boron compound 13 is diffused effectively into the silicon substrate 11, and an impurity layer 14 is formed inside the silicon substrate 11. Because only the surface of the silicon substrate 11 is heated intensively, a concentration of boron on the surface of the silicon substrate 11 is high. Because the whole of the silicon substrate 11 is not heated at a high temperature, the impurity layer 14 is never spread excessively inside the silicon substrate 11.

Title: Structure of fence panel
Inventor: TANIMOTO NORIHISA
IPC: B32B13/04
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To increase strength, make a thickness comparatively thin, and reduce execution work by constituting a fence panel by laminating and fixing a plate- like core material between ceramic surface plates. SOLUTION: A core material 2 composed of a plate having great strength such as an aluminum plate, a metallic plate such as a steel plate and a synthetic resin plate, is laminated and fixed between front and rear surface plates 1 by, for example, an epoxy-based or silicon-based adhesive and a pressure sensitive adhesive double coated tape, and a fence panel 3 is constituted. The surface plates 1 are formed on a ceramic material mainly composed of cement, and a surface pattern such as a recess-projection pattern is formed on a surface. In this way, since the fence panel 3 constituted by laminating and fixing the plate-like core material 2 between the ceramic surface plates 1 is the ceramic surface plates 1 in both surfaces, the whole presents ceramic external appearance, and becomes thin and strong in strength by laminating the plate-like core material 2.  An end part of the plate-like core material 2 is recessed or projected more than an end part of the surface plates 1 of front and rear surfaces, and a fitting recessed part or a fitting projecting part is formed, and adjacent fence panels 3 can be connected to each other.

IPC: G01N35/10
Filed: 1980-05-30
Abstract: PURPOSE:To make it possible to eliminate the waste of water used in washing jigs or the like, by controlling water supply and drainage to the signals from the water level detectors disposed adjacently to washing chambers corresponding to jigs, a drainage chamber and a pipetting tray. CONSTITUTION:A pipetting device washing chamber 7 and a coating tool washing chamber 8 are supplied with water from a feed water pipe 9. When the level of water in the water tank rises so that detectors a and b conduct to each other, according to the instructions from a controller 19, driving apparatuses 2 and 4 for a pipetting device nozzle 1 and a coating tool pen point 3 or the like are operated. Consequently, the respective jigs move downward into the respective washing chambers, and washing is started. In the washing, the water overflowing the washing chambers climbs over the partition part between a drainage chamber 6 and at the same time, flows therein through an overflow hole 21. When the level of water rises so that detectors c and d conduct electrically to each other, a solenoid valve 31 is opened as well as a pump 30 is driven, so that the water is discharged to a purifying tank 13 through a drainage path D. Thereby, it is possible to keep the amount of used washing water constant at all times and perform an effective washing with a smaller quantity of water.

Title: Pulse width control circuit
Inventor: MOROMIZATO HIDETO
IPC: H03K5/04
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To decrease the number of inverter type logic elements in use. SOLUTION: To a capacitor element 10, a charging circuit which applies the electric power of an external input power source Vcc to the capacitor element 10 through a phototransistor element 16 and the input terminal of a NOR gate NR 3 are connected. As the amplitude of the control signal applied to the photortransistor element 16 becomes larger, the charging speed of the capacitor element 10 increases and the pulse width of the pulse signal outputted from the NOR gate NR 3 becomes narrower. On the other hand as the said control signal becomes smaller, the charging speed of the capacitor element 10 decreases and the pulse width of the output pulse signal of the NOR gate NR 3 becomes wider. Inverter type logic elements for inverting the output pulse signal of the NOR gate NR 3 need not be provided, and consequently inverter type logic elements are decreased by the number.
