Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To prevent the application of a high voltage to a parallelly connected circuit, by providing an n-type layer and an electrode that can be connected to an external source at a distance closer to a p-type body layer than a distance between the p-type body layer and a drain layer. SOLUTION: When an N<+> -type source layer 13 is formed on the Surface of an N<-> -type semiconductor substrate 11, an N<+> -type drain layer 21 is formed at a place distant from a P-type body layer 12, and an N<+> -type layer 17 is formed at a place slightly distant from the layer 12 between the layers 12 and 21. An electrode 18 for connecting a parallel circuit and a source electrode 16 are connected to an external parallel circuit. When a power MOS is not conducting, a depletion layer formed on the substrate 11 is increased by the layer 12 so that the layer 17 is enclosed in the depletion layer. As a result, even if a high voltage (source voltage) is applied to the drain, no such high voltage as exceeding the voltage applied when the layer 17 is enclosed in the depletion layer is applied to the electrode 18.

That is, a substrate is heated at temperatures higher than 100 deg.C to softening temperature of the substrate and the partial pressure of oxygen is set at a higher level than 4 m Torr as preferential conditions. Further, the Ti oxide coat is formed in such a manner that the gradient of the number of electrons generated by the emission of ultraviolet rays having an energy above a specified value in terms of 1 μm of quantity of light at a work function of 4.5-6.0 eV, for an ultraviolet energy is 8.5 or less. The specified value is about 5.8 eV. When the Ti oxide coat 2 is formed on a glass 11, an undercoat of alkali barrier between the glass 11 and the Ti oxide coat 2 is necessary.

Abstract: PURPOSE:To form simply a system by generating required signals such as a normal response signal having a frequency and amplitude not giving remarkable hindrance to a substantial object of an MODEM and giving the signal to a frequency band occupied by the MODEM connected to a transmission line. CONSTITUTION:An analog signal generator 301 generating an analog signal such as a normal response signal is provided in a reception station A115 and the signal is given to a transmission line 103 from a branch point 303 via a line 302. The signal is detected by an analog signal receiver 305 provided in a transmission station 105 via a line 303 from a branch point 304. When it is necessay to transmit other signals such as a normal response signal, other analog information is transmitted with a sufficiently lower amplitude than the amplitude causing an error to a digital code reproduced by the MODEM to a band occupied by the MODEM connected to the analog transmission line. Thus, the required information is transmitted without using other communication line.

CONSTITUTION:The outer peripheral face of the grindstone 6 which is fitted to the tip of the spindle 5 supported by an electromagnet, reciprocated as well and rotated, is dressed by the multistone rotary dresser 13 of a dressing mean (a). In this case, an output line (b) excites the electromagnet, outputting the exciting current equivalent to the size of the load caused by the contact of the rotary dresser 13 and grindstone 6.

Title: Cleaning bench
Inventor: SOMATANI AKIFUMI
IPC: H01L21/304
Filed: 1991-04-22
Abstract: PURPOSE:To obtain a cleaning bench in which the splashing phenomenon of a liquid such as water, a chemical or the like is caused little at a cleaning operation by a method wherein a partition plate in which the opening area of a through hole for drainage use at the lower part is larger than that at the upper part is installed. CONSTITUTION:A through-hole sidewall (3-a) at a through hole 3 which has been made in a partition plate 2 is formed to be an inverted taper shape in a direction in which the opening area becomes large from the surface toward the rear surface of the partition plate 2. Thereby, most of a liquid 5 such as mater, a chemical or the like which has collided with the through-hole sidewall (3-a) changes its direction downward, and its splash to the upper-part protective wall of the partition plate is reduced. When an angle 9 formed by the partition- plate surface (2-a) and the through-hole sidewall (3-a) is at less than 90 deg. and it is set to be small within a possible range, a splash-restraining effect becomes large. Thereby, it is possible to avoid that the opening area at the lower part of the through hole becomes large more than required, and the strength of the partition plate can be kept and through holes can be arranged at high density.
