Title: Acoustic reproduction system
Inventor: YONEDA MICHIAKI
IPC: G10K15/12
Filed: 1994-06-30
Abstract: PURPOSE:To obtain the effect that a timing of a sound reproduced from a speaker and a timing of a sound reached directly from the speaker are in matching with each other at all times at a listening position by correcting a delay of the sound based on a temperature in the vicinity of the listening position. CONSTITUTION:A temperature sensor 25 is provided in the vicinity of a listening position being a reference of a hall and sensed data by the temperature sensor 25 are fed to a central controller 21 via an A/D converter 26. When sound is reproduced actually as a concert in the acoustic reproduction system, the temperature data at the listening position detected by the temperature sensor 25 are discriminated by the central controller 21 for each prescribed period (e.g. each minute) as to a difference between a current temperature and a temperature at the initial setting stored in a memory. Then the delay in digital voice data processing circuits 13a-13n is corrected in real time based on the discriminated temperature difference.

Title: Vibrative tool machining device
Inventor: SAOTOME TATSUO
IPC: B24B1/04
Filed: 1983-08-17
Abstract: PURPOSE:To suppress vibration of a device so as to perform high accurate machining, by setting the first and the second springs, which force a holding member mounted to the vibrative node of an ultrasonic vibrating part to be pressed to the side of a low frequency vibrating part and the low frequency vibrating part to be pressed to the side of the holding member, further providing the third spring between the both vibrating parts. CONSTITUTION:An ultrasonic vibrating part comprises an electrostrictive vibrator 3 connected to a horn 2 fixed to a tool 1. A low frequency vibrating part, comprising a holding member 5 connecting one end of a plunger 6, the plunger 6, bobbin 7, winding 8, stator 9, screw 10 and a plate 11, is slidably inserted into an outer cylinder 12. The ultrasonic and low frequency vibrating parts, if they are driven by oscillating machines 19, 20 respectively, apply vibration overlapping the ultrasonic and low frequency vibrations to the tool 1 to perform high efficient machining, but the low frequency vibration relaxes a shock due to vibration to the outer cylinder 12 by moving the respective mass of the ultrasonic and low frequency vibrating parts in an opposite direction so as to cancel inertia force by the cooperative action of the second and the third springs 17, 18 with the first spring 16.

IPC: F02M69/00
Filed: 1981-09-22
Abstract: PURPOSE:To increase the efficiency of fuel consumption of an internal combustion engine, by ejecting fuel from a nozzle disposed in a vaporizing container, baporizing fuel in the container, and drawing the vaporized fuel into an intake pipe at a required rate. CONSTITUTION:In feeding vaporized fuel into a fuel supply pipe 1, liquid fuel in a fuel tank 10 is at first drawn up by a pump 13. Then, the liquid fuel is sprayed, under a high pressure, upward from an injection nozzle 12 disposed near the bottom of a conical vaporizing container 8, the diameter of which is decreased toward its top, at a rate greater than the quantity into the fuel supply pipe 1 by the negative pressure. Here, the particle sizes of fuel are reduced toward the top of the container 8 and vaporization of fuel is promoted, whereas the particle sizes of fuel near the inner wall surface of the container are relatively large, so that the fuel near the inner wall surface of the container is recovered into the fuel tank 10 via revovery pipe 9. Only the vaporized fuel in the container 8 is drawn into the pipe 1 and supplied to an engine 3 through a venturi 5.

Title: Solid-state image pickup device
Inventor: HORII SAKAKI
IPC: H04N9/07
Filed: 1979-11-19
Abstract: PURPOSE:To prevent color mixture due to the mixing of signal charge among different picture elements, by forming zigzag many channel cut-off areas for sectioning respective picture elements. CONSTITUTION:Channel cut-off areas 4 zigzag by being bent at repetitive intervals of a transfer gate. Then, areas 4 reside between sections where the color filter changes in color. Consequently, charge generated by light incident to transfer gate electrodes 21 and 22 can not move to the potential well under transfer gate electrode 19 of different picture elements in color filter sections and the signal charge moves only to transfer gate electrode 23 of picture elements in the same color filter sections. Thus, the movement of the signal charge between picture elements differing in color filter section is inhibited to prevent color mixture.

Abstract: PURPOSE:To expedite the measurement of groups of points on the inner and outer walls of a structure, by providing a laser beam projector whose measuring range can be switched over between long-distance and short-distance modes, and by measuring the coordinates values of groups of main control points and reference control points sequentially by both modes. CONSTITUTION:A laser beam projection type three-dimentional measuring device whose measuring range is set in a long-distance mode is installed at a central base point W, a laser beam is projected to primary reference control points P1 and P2 whose coordinates values are already known, and thereby the coordinates value of the base point W is determined. Next, the laser beam is projected to groups K1-K5 of main control points so as to measure the respective coordinates values. Then, the measuring device is switched over to a short-distance mode and transferred to a second position C1, and the coordinates value thereof is determined.Thereafter the coordinates values of groups S1-S9 of object points of measurement are measured. Furthermore, the measuring device is transferred to a third position C2, and groups S10-S23 of object points of measurement are mesured by the same procedures. By this method, the measurement of the groups of points constituting the inner and outer walls of a structure can be performed rapidly.

IPC: G10L19/113
Filed: 1989-06-14
Abstract: PURPOSE:To enable encoding into an audio signal of good sound quality by combining a spectrum parameter and an initial phase with the amplitude of an audio source pulse train. CONSTITUTION:An audio signal sequence is sectioned while shifted by the predetermined number of samples and the sectioned sound signal sequences are used to extract the spectrum parameter showing a short-time spectrum envelope and calculate an impulse response sequence; and the autocorrelation function sequence of the impulse response sequence and the cross-correlation function sequence between the audio signal sequence and impulse response sequence are calculated. The cross-correlation function sequence is used to find the initial phase of a driving sound source signal and perform the encoding, and the autocorrelation function sequence, the cross-correlation function sequence, and the initial phase of the driving sound source signal are used to find the amplitude sequence of the driving sound source signal for the sound signal sequence and performing the encoding. Then the code of the spectrum parameter, the code indicating the initial phase of the driving sound source signal, and the code indicating the amplitude sequence of a former-half driving sound source signal are outputted in combination.

Title: Ribbon driving mechanism for typewriter
Inventor: CHIYAARUSU SUTANREE ARUDORITSU
IPC: B41J35/20
Filed: 1982-09-01
Abstract: @ A ribbon lift and feed mechanism for a typewriter/ printer (10) in which the print ribbon cartridge (15) has deflectable arms (16a, 16b) for placing the ribbon (13) in a position confronting the platen (11) of the typewriter (10). On the platform (40), supporting the ribbon cartridge (15), is a shuttle (50) which is remotely oscillated as by a drive motor (90) on the frame (12) of the typewriter (10). Translation of the shuttle (50) and the cam (66) associated with the shuttle (50) effects movement of cam follower (66a) engageable with the cam (66), causing the deflectable arms (16a, 16b) of the cartridge (15) to oscillate between a rest and elevated position to place different portions of the print ribbon (13) intermediate the type element (23) and the platen (11). The shuttle (50) also carries ribbon feed drive means (85) which cause an incremental feed of the ribbon (13) after the ribbon has been struck at multiple elevated positions. Moreover, by placing a correction ribbon cartridge (30) beneath the ribbon cartridge (15), another cam (70) on the shuttle can effect platform (40) elevation when it is desired to dispose the correction ribbon (31) intermediate the printing element (23) and the platen (11). This action occurs as a result of the oscillation of the shuttle (50).
