Title: Ultrasonic grinding device
Inventor: SHIMAOKA HIROYUKI
IPC: B24B1/04
Filed: 1986-01-09
Abstract: PURPOSE:To prevent the occurrence of the useless slip and damage of a grinding stone and to perform efficient grinding, by a method wherein a machining pressure, exerted on a workpiece, is detected, and the axial feed of a grinding stone shaft is controlled between an upper and a lower limit value, which are set according to a kind of the workpiece. CONSTITUTION:Depending upon a kind of a workpiece 12 and a grinding stone 10, a lower limit value P1 of a machining pressure is determined to a value higher than a machining starting force, and an upper limit value P2 is determined to a value lower than a maximum machining pressure set from an actual data and an experience value. When, with a driving motor 3 and an oscillator 9 driven, rotation and vibration in an axial direction are applied on a diamond grinding stone 10 of a rotary shaft 2 and an axial feed is effected, the tip of the grinding stone 10 is started to enter the workpiece 12. In this case, machining pressure, exerted on the workpiece 12, is compared with the upper limit value P2 and the lower limit value P1 previously set in a sequence circuit through a load cell 13 for decision, and the feed starting is switched each time a machining pressure is collided, and the machining pressure is pulsated between P1 and P2 to grind the workpiece with high efficiency.

Title: Feeding circuit
Inventor: AYANO MITSUTOSHI
IPC: H04M19/00
Filed: 1985-01-14
Abstract: PURPOSE:To obtain a low impedance with respect to the same phase signal of and induced noise, etc. by providing a buffer amplifier of an amplification gain 1 connected to a subscriber's line through a resistance, a resistance for voltage-dividing an AC signal such as a sound signal, etc. and feeding it back to an input terminal of the buffer amplifier, and a current mirror circuit having a specified impedance. CONSTITUTION:A DC voltage Vf of a terminal RING is applied to a terminal M1 of a current mirror circuit MR1 through a resistance RR3. In this case, an AC component is absorbed by a capacitor CR1, and a current flowing to the terminal M1 of the current mirror circuit MR1 becomes Vf/RR3. As a result, the same current as this current flows to terminals M2, M3, and a supervising circuit SVR connected to the terminal M3 supervises a current flowing to a telephone set from the terminal M1, and detects on-hook and off-hook of the telephone set. This detecting signal is transferred to a central control equipment through a scanning circuit, etc. of a switchboard. Also, a voltage Ve is formed by a current flowing to a resistance RR2 connected to the terminal M2. In this case, no DC current flows because a capacitor CR2 is connected to an impedance Z1.

Abstract: PURPOSE:To enhance the integration of a semiconductor device by a method wherein the region to connect an N type silicon substrate and a polycrystalline silicon resistor element and a P well are made to be isolated by a field oxide film by self alignment. CONSTITUTION:An N type epitaxial layer 52 having high concentration and an N type epitaxial layer 53 having low concentration are formed on the N type silicon substrate 51. The P well 60 and N wells 61, 62 are positioned and formed without passing through the masking process after a field oxide film 55 is formed.

The N wells 61, 62 are connected to the epitaxial layer 52, and electric power is taken out from the epitaxial layer 52 to act as the wiring layer. Accordingly because the P well and the N wells are formed after formation of the oxide film 55, to make allowance for discrepancy of positioning of mask is unnecessitated, and integration can be enhanced.

Inventor: OKADA ATSUNORI
IPC: H01J65/00
Filed: 1992-01-14
Abstract: PURPOSE:To provide an electrodeless electric drscharge lamp which can be easily started. CONSTITUTION:An inductive coil 2 is wound in the circumferential direction of a bulb 1 formed as an annular tubular body. A ring shaped inductive electric field generated by the electric conduction of the high frequency current in the inductive coil 2 is applied to the electric discharge gas introduced into the bulb 1, and the annular electric discharge is generated. When the high frequency voltage is applied between a starting assisting electrode 3 installed on the outer peripheral surface of the bulb 1 and the ground, a streamer is generated from the starting assisting electrode 3, and the preliminary electric discharge is generated. If the inductive coil 2 is applied with the high frequency current in the state where the preliminary electric discharge is generated, the charged particles are generated by the preliminary electric discharge, and the transition to the annular electric discharge is facilitated. Further, since the generation region of the preliminary electric discharge is superposed with the formation region of the inductive electric field due to the inductive coil 2, the transition to the annular electric discharge from the preliminary electric discharge is facilitated.

Title: Production of epoxy resin
Inventor: TOYOSHIMA YOSHIKI
IPC: C08G59/02
Filed: 1982-01-14
Abstract: PURPOSE:To obtain an epoxy resin capable of forming products of improved yield and quality, by neutralizing an excess dechlorinating agent or dehydrochlorinating agent with carbon dioxide in the production of an epoxy resin comprising a glycidyl ether of phenol. CONSTITUTION:In the production of an epoxy resin comprising a glycidyl ether of a mono- or polyhydric phenol, the excess portion of a dechlorinating agent or dehydrochlorinating agent used in the dechlorination or dehydrochlorination step, such as an alkali metal or alkaline earth metal hydroxide or chlorine, is neutralized with carbon dioxide. In the above process, since carbon dioxide is used as a neutralizing agent the salt formed by neutralization has a very high m.p. as compared with a salt which is formed by using phosphoric acid or the like as a neutralizing agent and, therefore, the formed carbonate salt does not melt under the reaction conditions for producing the epoxy resin. Accordingly, it is possible to remove the salt directly by filtration.
