IPC: H04M3/42
Filed: 1988-03-29
Abstract: PURPOSE:To reduce the number of functional buttons so as to make sure conference speeches possible by diverting the functional button of a called-side extension telephone set whose original function becomes invalid just before a conference speech starts, to a functional button for conference speech. CONSTITUTION:When a holding key H1 is actuated by depressing a holding button while a telephone sect TEL1 is busy with a line wire CO, the actuation is detected by a key actuation detecting section 4 and a central control section 6 sets the line wire CO to a holding state by controlling a line wire control section 2. When the extension call button is depressed and the extension call key K1 is closed at the telephone set TEL1 thereafter, the detecting section 4 detects it and the control section 6 calls the called telephone set TEL2 so as to make speeches possible between the telephone sets TEL1 and TEL2. When the holding button is depressed at the telephone set TEL2 in such state, the control section 6 sets channels among the telephone sets TEL1 and TEL2 and line wire CO by controlling a switch 1 and cancels the holding state of the line wire CO by controlling the control section 2. Therefore, conference speeches become possible among the telephone sets TEL1 and TEL2 and line wire CO.

Filed: 1988-03-29
Abstract: PURPOSE:To discriminate the high and low potential of input signals and, at the same time, intermediate potential by providing an intermediate potential discriminating circuit constituted of plural inverters and an exclusive OR. CONSTITUTION:An inverter 203 which works as a high/low potential discriminating circuit makes its high/low potential discriminated output 208 low in potential when the potential of input signals 207 is higher than the input potential (logic level) which inverts the output of the inverter 203 and high in potential when the potential, of the input signals 207 is lower than the input potential. Moreover, in an intermediate potential discriminating circuit 202 constituted of inverters 204 and 205 and an exclusive OR 206, the logic level is set higher than that of the inverter 205. The intermediate potential discriminated output 209 of the circuit 202 becomes high in potential only when the potential of the signals 207 is at intermediate potential between the logic levels of the inverters 204 and 205. Therefore, the intermediate potential of the signals 207 can be discriminated. Therefore, this circuit can discriminate the intermediate potential of input signals in addition to their high and low potential and, accordingly, can have three kinds of functions against one input.

Filed: 1982-05-07
Abstract: PURPOSE:To enable the temperature of an outer tube to be efficiently controlled by providing a thermal-radiation-shielding plate made of a metal, glass, ceramics or the like between a space formed between the outer tube bulb and the inner tube. CONSTITUTION:A nickel plate of 2cm square used as an infrared-ray-shielding plate 13 is fixed in the middle between an outer tube 6 and an emission tube 7 by use of a band 11 and a supporting bar 12. When the temperature of the surface of the outer tube 6 is measured after the electric-discharge lamp is lit at room temperature (25 deg.C) and 20W, it is observed that the temperature of a part which is shaded by the shielding plate 13 is suppressed to around 40 deg.C although those of parts which are not shaded by the shielding plate 13 increase to 55 deg.C- 60 deg.C. Since such a shielding plate used for preventing the radiation of infrared rays doesn't require any nearly isolated space as a member which is used for preventing thermal conduction and convection, there is no need to install the shielding plate extremely close to the tube wall and to use a large plate which almost covers the sectional area of the tube. Therefore, the shielding plate can be manufactured easily.

Title: Method and device for dry etching
Inventor: HAYASAKA NOBUO
IPC: H01L21/302
Filed: 1986-04-02
Abstract: PURPOSE:To perform high-accuracy directional etching controllably to prevent damage to a surface of a processed substrate, by generating ions by optical excitation and then providing the ions with directionality by an electric field so that etching is performed. CONSTITUTION:D-c voltage is impressed on a sample board 13, and an electric field is impressed in the direction vertical to the surface of the substrate 12 at the vapor phase part near the surface of the processed substrate 12, and vacuum ultraviolet rays 26 are radiated close to the surface of the substrate 12. Radiation of the ultraviolet rays 26 causes ions, which are made by ionizing gaseous molecules by light in the vapor phase near the surface of the substrate 12. These ions are made incident to the surface of the substrate 12 by the electric field existing in the surface. Thus, anisotropic etching of P-addition polycrystal Si can be performed in a state of no trailing. Hence, controllable and high-accuracy directional etching is performed, preventing damages on the surface of the substrate 12.

Title: Hydraulic control system
Inventor: YOSHINARI TAKAMASA
IPC: F15B11/00
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To improve a pressure control characteristic with a reduction in cut-off range, and a dynamic characteristic at the time of switching from flow control to pressure control. SOLUTION: When pressure liquids discharged from variable delivery hydraulic pumps 4 and 5 are joined via a check valve 1 by operating a direction switching valve 6, an operating command input means 30 outputs an operating pressure command value Sp2 identically for control devices 18 and 27. At that time a pressure signal switch 15 switches each control pressure signal of the variable delivery hydraulic pumps 4 and 5 to a pressure signal of a pressure detector 7a. Thereby an increase in cut-off range due to a pressure loss of the check valve 1 and a control oscillation phenomenon due to a rapid shutoff of the same are prevented. And a head differential set switch 16 outputs an operating signal Sh2 to a control valve 9 such that a pressure P2 is controlled much lower than a pressure P1.

IPC: F16K3/30
Filed: 1982-05-08
Abstract: PURPOSE:To prevent the occurrence of stress corrosion cracking, by forming a joint portion at the top of a vertically movable valve rod, forming a groove for receiving the joint portion in a valve element such that it extends axially substantially in the same direction as valve seats, and thereby reducing the stress produced at corner portions of the bottom surface of said groove. CONSTITUTION:A joint portion 4 formed at the top of a vertically movable valve rod 3 is fitted in a groove 10a formed in a wedge-shaped valve element 10, and a conduit 7 formed in a valve box is opened and closed with upward and downward movement of the valve rod 3. The groove 10a is formed to extend axially in the same direction as valve seats 6a, 6b formed in the valve body. Therefore, when the valve element 10 is moved downward and comes into engagement with the valve seats 6a, 6b, the force applied to the groove 10a by the joint portion 4 is transmitted smoothly to the valve seats 6a, 6b, so that the stress produced at corner portions of the bottom of the groove 10a can be reduced.
