Title: Gas flow selector
Inventor: MARUYAMA KENJI
IPC: F16K17/02
Filed: 1987-03-20
Abstract: PURPOSE:To perform high temperature and corrosive gas directional control, by installing a valve which is movable between both gas inflow and outflow ports installed in a pipe and capable of closing either side of these inflow and outflow ports. CONSTITUTION:An inflow port 4 and an outflow port 5 both re installed in a gas pipe 1, and a gas stop plate 2 movable up and down is installed between these inflow and outflow ports 4 and 5 in addition. This gas stop plate 2 is usually situated in the position closing the inflow port 4 before gas is made to flow, and at the time of letting the specified gas flow, it is moved to the position where both these inflow and outflow ports 4 and 5 are opened, thus gas is delivered. Both up and down characteristics of the gas stop plate 2 are varied so as to alter each diameter of these gas inflow and outflow ports 4 and 5, and a distance between them, weight of the gas stop plate 2, and the form. With this constitution, high temperature and corrosive gas directional control can be carried out, thus a high-grade semiconductor wafer is attainable.

Title: Compound semiconductor growth and semiconductor device
Inventor: TOSAKAI NOBUAKI
IPC: H01L21/205
Filed: 1990-03-16
Abstract: PURPOSE:To avoid the development of any crystal defects during the oxygen doping process as well as the mixture of doping oxygen gas with the growing compound semiconductor in the next stage by a method wherein an organic metal compound having direct coupling of Al atoms and O atoms is contained in a source gas in an organic metal vapor growing process. CONSTITUTION:An organic metal compound having direct coupling of Al atoms and oxygen atoms is used as a doping gas in a source gas 2 of aluminum. That is, the Al-O organic compound having initially coupled Al atoms and oxygen atoms can be efficiently absorbed into a crystal. Besides, the oxygen will not separate from Al due to the intensive coupling force with each other even if there is any residual oxygen in a reaction furnace 1 at all. Accordingly, even if high purity crystal is continuously grown, no oxygen will be mixed therewith while avoiding the production of any oxide of the other elements which develop defects.

IPC: F02B77/13
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To reduce noise efficiently without any huge increase in weight by providing a resonator, whose housing inside space is divided by means of a diaphragm and a low rigidity member around it, and directly transmitting vibration of a structure to the diaphragm in the resonator by means of a connecting mechanism. SOLUTION: If a vibrating face 1 such as an oil pan of an engine generates membrane vibration, noise is radiated in a sound field space 2. In the sound field space 2, a resonator 3 is supported via a stay 4. In the resonator 3, one face of its housing 5 is formed of a diaphragm 6, which is connected to the housing 5 via a low rigidity member 7. On the other hand, the diaphragm 6 is connected to the approximate center of the vibrating face 1 via a connecting rod 8, and the diaphragm 6 is vibrated similarly with the vibrating face 1 according to the membrane vibration of the vibrating face 1. In this way, an inside space of the resonator 3 is vibrated, and the phase of radiation noise generated because of this vibration is reversed while taking a resonance frequency of the resonator 3 as a boundary, so that noise can be effectively reduced.

Abstract: PURPOSE: To protect a piezoelectric speaker from a thermal fault, owing to an excessive input by serially connecting a positive temp. coefficient(PTC) resistance to the piezoelectric speaker and connecting a PTC nonlinear resistance which is connected to the resistance in parallel. CONSTITUTION: A nonlinear resistance circuit 10 which is serially connected to the piezoelectric speaker 12 is driven by a voltage between terminals 14. The circuit 10 consists of a resistance element 16 and the resistance element 18 being in parallel with it. The element 16 is provided with a nonlinear resistance-temp. characteristic and is constituted of the PTC resistance. The element 18 is the PTC resistance providing the nonlinear resistance-temp. characteristic which is different from that of the element 16 and is constituted of, for example, an incandescent lamp. In the nonlinear resistance-temp. characteristic of the element 16, resistance sharply increases as temp. ascends from 120 deg.C, as shown in the figure. Thus, the voltage applied to the speaker 12 is reduced, so that thermal dissipation by the speaker 12 is rest.  The element 18 limits max. resistance which is supplied from the circuit 10.
