Title: Chip type porcelain capacitor and manufacture thereof
Inventor: AKAHO TETSUO
IPC: H01G4/224
Filed: 1990-05-29
Abstract: PURPOSE:To obtain a chip-type semiconductor porcelain capacitor which has no or little exposure of the glass component of an insulating layer on burned metal films which serve as edge electrodes by using a glass insulating layer whose glass component is softened or melted at the higher temperature than the glass frit contained in the edge electrodes. CONSTITUTION:Metal paste is applied to the front and rear principal planes of a semiconductor porcelain base substance 10 and is burned to be electrodes 11 which face each other. Each of the facing electrodes 11 is formed on each principal plane with the specified distance left over from each end face 10a. The distance left over is equal to the thickness of the semiconductor porcelain base substance 10 or more than that. On almost all the front and rear principal planes and on side faces 10b of the semiconductor porcelain base substance 10, in other words, on almost all the surface of the semiconductor porcelain base substance 10 except for the end faces 10a, an insulating glass layer 12 is formed. And edge electrodes 15 are so formed as to cover the end faces 10a and parts of the facing electrodes 11 which are exposed on the front and rear surfaces near the end faces 10a which face each other. Since the insulating glass layer 12 which is formed on the front and rear surfaces and on both side faces 10b of the semiconductor porcelain base substance 10 is softened and melted at the higher temperature than the glass frit contained in the edge electrodes 15, the insulating glass layer 12 can be formed at the higher buring temperature than the edge electrodes 15.

Title: Ignition device in internal-combustion engine
Inventor: IMASHIRO MINORU
IPC: F02M57/06
Filed: 1984-07-09
Abstract: PURPOSE:To ensure the ignition of an engine even if either one of electrodes cannot spark, by arranging a plurality of ignition electrodes in the peripheral section of a space through which atmoized fuel stream from a fuel injection device passes, and by arranging spark gaps in the electrodes in parallel with each other. CONSTITUTION:An atomized fuel stream injected from a jet port in a fuel injection valve reaches a through-hole, and is evaporated successively from liquid drops. The thus evaporated fuel is mixed with air introduced from the outer peripheral edge of the atomized fuel stream to form a burnable mixture while the evaporated fuel passes through spark gaps 23 and moves toward a vortex chamber. An ignition voltage applied to a high spark voltage supply section 12 allows one of spark gaps 23 which is easiest to spark, to generate a spark while the other spark gaps 23 do not spark since the spark gaps 23 establish parallel gaps. Accordingly, even if the position of the atomized fuel stream is shifted, natural spark is effected at a spark gap 23 which has a maximum possibility to make in contact with this atomized fuel, and the spark initiation voltage may be made lower and the ignition may be stabilized.

IPC: G06F1/06
Filed: 1991-05-17
Abstract: PURPOSE: To use a digital processor with a peripheral equipment having a variable access time without decreasing the basic clock frequency of a microprocessor, that is, without adding a microprocessor waiting state. CONSTITUTION: Normally, a clock pulse is connected with a microprocessor 11 which can perform access to memory devices 13 and 14 having different access time by a clock circuit 12. The access to the 'low speed' memory device 14 is detected by the pertinent clock circuit, and at least one clock pulse is not connected with the pertinent microprocessor in response to it. The operation in the proper amounts of the pertinent microprocessor is delayed so that the pertinent microprocessor can read the effective data from the pertinent slow memory device. The number of clock pulses whose arrival at the pertinent microprocessor is interrupted can be set by a certain delaying circuit in the pertinent clock circuit.

Inventor: OSADA KAZUSANE
IPC: G01N27/416
Filed: 1994-06-23
Abstract: PURPOSE:To enable accurate evaluation of esthesiophysiological influence by a method wherein an object to be measured is placed into an oral cavity of a vertebrate other than a human being for a fixed time and hourly changes in intensity of reaction of neurocytes among the neurocytes of an animal reacting specifically on a single taste are detected. CONSTITUTION:An anesthetic such as pontobarbital is administered to a rat and a part of tympanic cord is exposed from the side of a face to keep electrodes 1 and 1 in contact with neurocytes thereof. Then, a sweet substance is bought into contact with a tongue of the rat. As a result, a transmission mechanism of taste stimulation to a living body starts to generate an impulse. The impulse is inputted into an arithmetic means 4 through an amplifier 2 ands a level discrimination means 3 and the results integrated are outputted to a display means 5 as intensity of reaction, Likewise, individual neurocytes reacting specifically to acidity and bitterness are specified. Thus, for example, multiple kinds of drinks and sample solutions are dropped on the tongue of the rat to display changes in the intensity of reaction on sweetness, acidity, bitterness and salty taste of the individual drinks.

Abstract: PURPOSE:To form effective refractive index distribution difference in a lateral direction and to control the oscillation of a basic mode by forming an upper clad layer on an active layer in a superlattice structure, and forming the exposed face as a nonoxidative thin film. CONSTITUTION:A P-type Al0.3Ga0.7As clad layer 2, an active layer 3, an N-type superlattice clad layer 4 and a P-type GaAs layer 5 are sequentially grown in this order on a P-type GaAs substrate 1. The layer 4 is formed by alternately laminating a thin film 6 as an AlAs layer and a thin GaAs film 7 as a nonoxidative thin film. Then, the layer 5 is etched to form a stripe groove 8 and the remainder of the layer 5 is formed as a current constriction layer 5'. Thereafter, an N-type superlattice clad layer 9 is so regrown that aluminum has the same ratio as that of the layer 4, and an N-type GaAs ohmic contact layer 10 is then grown in a predetermined thickness. In this regrowth, an N-type diffused clad layer 11 in which its refractive index is reduced by disordering the layer 4 is formed under the layer 5'.

Title: Speech pitch extracting device
Inventor: IWATA KAZUHIKO
IPC: G10L25/90
Filed: 1988-06-08
Abstract: PURPOSE:To calculate a pitch frequency by inputting a speech signal and detecting a zero-cross position, finding the area of a speech during the period, and finding the primary difference value of a position or area corresponding to the periodic vibration of the vocal chords from the area. CONSTITUTION:A speech signal to be processed is inputted to a speech input terminal 11 and sent to a voiced sound section detection part 12. The voiced sound section is detected by a conventional method. A zero-cross position detection part 13 detects the voiced sound section from the position where the sign of the speech signal of the voiced sound section is inverted and an area calculation part 14 finds in-zero-cross power and sends it to a primary difference calculation part 15. The difference from last area is calculated and a pitch position extraction part 16 extracts in-zero-cross power corresponding to the periodic vibration of the vocal chords from the difference value. Namely, the maximum in-zero-cross power is found in the section of time length which is the reciprocal of the pitch frequency at which it is considered that the highest input speech is obtained, and extracts the in-zero-cross power at a position corresponding to the vibration of the vocal chords. A pitch frequency calculation part 18 calculates the pitch frequency from intervals of said zero-cross positions.
