Title: Randam oriented polycrystalline silicon carbide coating for abrasive granules
Inventor: SUTEFUAN CHIYAARUZU HAIDON
IPC: C09K3/14
Filed: 1982-02-26
Abstract: Disclosed is a composite abrasive particle comprising a core abrasive crystal and a silicon carbide coating adherently bonded to substantially all of the exterior surfaces of said core crystal, said silicon carbide coating characterized by silicon carbide crystals having a random orientation substantially independent of the structure of the core crystal, the outer surface of the coating being conformationally irregular. Aggregates of the composite abrasive particles are interconnected by a matrix of silicon carbide which has an open structure. Preferred core abrasive crystals are diamond or cubic boron nitride. The composite abrasive particles preferably are male by infiltrating core crystals coated with non-diamond carbonaceous material with fluid silicon to produce a mass of core crystals bonded together by silicon carbide and elemental silicon, leaching substantially all of the silicon from the bonded mass with a silicon leaching agent, sub-dividing the resulting leached mass, and recovering the composite abrasive particles.

Title: Plasma treatment apparatus
Inventor: TSUKAMOTO YUJI
IPC: H01L21/302
Filed: 1994-02-03
Abstract: PURPOSE:To provide a plasma treatment apparatus in which a stable discharge can be obtained and which is provided with a space-saving power-supply circuit. CONSTITUTION:In addition to a main power supply 33 which can apply a high current to a main discharge electrode 11, an auxiliary power supply 36 which can apply a high voltage to a spare discharge electrode 10 is installed. As a result, since an initial discharge at a rise is stabilized and an overcurrent does not flow to the spare discharge electrode 10, a plasma can be shifted smoothly to an intermediate chamber 14 from a cathode chamber 14A. In addition, although the number of power supplies is increased, the power supplies which are small are used, and a space-saving apparatus as a total space can be constructed.

Abstract: PURPOSE:To minimize the discrepancy between the data recording position and the position of a reading out head, by detecting the reference trace for position detection previously recorded on a floppy disk, and calculating the distance from a reference track, then positioning a head based. CONSTITUTION:When a disk is rotated under a condition where the recording center and rotating center are deviated each other by an amount delta1, a reference track read-out signal is shown by a signal S6.

A signal S4 for compensation is obtained by accumulating a compensation pulse signal S3 generated between the Xn-1 and Xn of the rotating position signal S2. When the above mentioned signal S4 for correction is acted correspondingly to the rotating position signal S2, on a track to be used for recording or reading data, the loci of the upper head on a floppy disk are shown by 4C and 2C, and the maximum deviation amount delta2 is made far smaller than that of delta1.

Abstract: PURPOSE:To provide gradation to a ridge line by applying shaping process to a horizontal fundamental waveform and a vertical fundamental waveform so that the level of them varies in a range from 0 to 1, multiplying the waves for the synthesis and generating an output waveform. CONSTITUTION:A horizontal fundamental wave generating circuit 11 generates a fundamental waveform Wh with a prescribed horizontal period.

Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To provide a radiation heater having an active sensor by making a very accurate signal to control the heater exist even in the case of a simple and strong sensor structure. SOLUTION: An electric radiation heater 11 is manufactured by having a pot detecting system 31 to put switches in one or more heating areas 18 and 19.

Title: Picture element position recognition of solid-state image pick-up device
Inventor: SONE KENRO
IPC: H04N5/217
Filed: 1985-02-22
Abstract: PURPOSE:To make it possible to recognize a picture element position using a simple circuit configuration by making one counter have functions as vertical position counter, horizontal position counter, vertical position latch, horizontal position latch and vertical/horizontal correspondence detecting parts. CONSTITUTION:When VP pulse trailing is detected by the control part 14, a vertical data load pulse is outputted to the line 16. Then it is synchronized with the vertical data load pulse, and the vertical relative position data is loaded to the 4-bit position counter 17, which consists of respective registers, ie, counter A data, counter B data, counter C data and counter D data, from the ROM 6. The vertical relative position data of the position counter 17 is counted up with the WHD pulse inputted to the line 18, the vertical relative position is recognized and the horizontal data load pulse is outputted to the line 16. After these operations, the data synchronizes with the horizontal data load pulse to load the horizontal relative position data from the ROM 16 to the position counter 17. Thus this realizes the reduction of power consumption of the LSIs and the minimization of packages.

Title: Ionization detecting device
Inventor: KAMIGAKI HIDEYUKI
IPC: G01N30/64
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To increase an ionization efficiency. SOLUTION: A cylindrical emitter 14 of which side peripheral surfaces are made of ionization metal is provided in an ionization chamber 11 and an oxidization chamber 12 so that a part of the side surfaces can be exposed. When, the emitter 14 is rotated continuously, the surfaces of a metal oxide is exposed to the inside of the ionization chamber 11 immediately after it is oxidized in the oxidization chamber 12, and those molecules injected from a nozzle 18 toward the surfaces of the metal oxide are ionized by surface separation. Thus, because the surface of the metal oxide of which work function is higher is always used for the ionization action, the ionization is performed efficiently. In addition, because oxygen gas is not introduced into the ionization chamber 11, there is no danger that a collector 19 is damaged by oxygen gas.

Abstract: PURPOSE:To prevent thermal cracking due to the excessive rising in temp. or an adsorption phenomenon due to the excessive lowering in temp., by applying program control to the rising in the temps. of an interface, a gaseous specimen introducing pipe and an ionizing chamber in matching relation to the rising in the temp. of a GC column thermostatic tank. CONSTITUTION:In an analytical apparatus consisting of a gas chromatograph and a mass analyser, the temps. of a GC interface 2, a gaseous specimen introducing pipe 4 and an ionizing chamber 5 is raised in synchronous relation to the rising in the temp. of a GC column thermostatic tank 1 by program control. By this method, the temp. raising program from the outlet of the column thermostatic tank 1 to the ionizing chamber 5 can be freely set and, therefore, a situation such that dehydration or demethylation is generated by heat before ionization and the molecular ion on a mass spectrum is not detected is eliminated. The high b.p. compound in a high mass region can be also detected and, because the specimen is not adsorbed, the detection of a minute amount can be performed.
