Title: Suction air flow detector of internal combustion engine
Inventor: OKAMOTO OKIMICHI
IPC: F02D35/00
Filed: 1983-05-02
Abstract: PURPOSE:To assure an output performance, etc. and improve accuracy of detection of suction air flow, by making a cross-sectional area of suction passage variable of detecting cylinder assembled part of a hot-wire type flow detector according to an operating condition of engine. CONSTITUTION:In a low load range with a small suction aif flow, a suction vacuum in action on the inside of piston 17 is low and a length of downward stroke of piston 17 is short and consequently, a cross-sectional area of suction air passage of a detecting cylinder assembled part is reduced, tending to increase a suction air flow rate in the detecting cylinder 12 is increased. Under this situation, a fluctuation of output voltages from a detection circuit 13 relative to a fluctuation of suction air flow quantities becomes significant, an accuracy of suction air flow detection is improved and thus, on accuracy of fuel injection quantity can be improved. On the other hand in a heavy load range where the suction air flow is significant, the piston downward stroke length is increased, increasing the suction air passage area in the area where the detecting cylinder 11 is assembled becomes increased and frictional resistance in the suction air passage resistance can be reduced and consequently, a heavy load performance can be assured.

Abstract: PURPOSE:To measure the change of the surface temperature of an object when a person comes close to or touches the object by a method wherein a sample is placed in the circumstance where the temperature and humidity can be changed and, at least the humidity is changed. CONSTITUTION:Temperature/humidity variable devices 1, 1' are comprised of space parts A, B and thermo-hygrostats A', B' provided in the space parts A, B, respectively. A sample 4 is st at a fixing part 3. An air in a predetermined transient state the humidity of which is adjusted by the device A' is circulated in the space part A of the device 1 by a circulating device 9. Meanwhile, an air adjusted by the device B' is circulated to the space part B of the device 1'. The air to be circulated in the space part B may be in the stationary state or changed to be not stationary upon necessities. Although it is preferable that no pressure difference is present between the space parts A and B, the pressure in the space part A may be set higher upon necessities to flow the air from the space part A to the space part B through within the sample. In this manner, the sense or feeling of a person when the or she comes close to or touches an object can be quantified.

Title: Light interference reflecting mirror
Inventor: KAWAKATSU AKIRA
IPC: G02B5/28
Filed: 1988-03-31
Abstract: PURPOSE:To prevent the decrease in transmittance occurring in the mutual interference of light by providing light interference reflecting films respectively to both faces of a glass base body having a non-parallel relation. CONSTITUTION:The glass base body 1 is so formed that the reflecting face 11 thereof and the rear face 12 thereof are not in the parallel relation. The greater part of visible rays V1 are successively transmitted through visible ray transparent IR reflecting films 2, 3 and are radiated backward. A part of the visible rays V2 are reflected by the 2nd visible ray transparent IR reflecting film 3 on the rear face and advances toward the 1st visible ray transparent IR reflecting film 2 of the reflecting face 11. A part V3 thereof reflects again on the reflecting film 2 and advances toward the rear face. However, the rear face 12 is not parallel and, therefore, the reflected rays V2, V3 pass the routes different from the incident light R and the transmitted visible rays V1. The attenuation of the visible rays by the interference is thereby decreased and the overall transmittance is improved.

Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To protect copyright as far as possible although a high speed dubbing function can be used, by clocking a prescribed time by making it correspond to discriminating information for identifying a program as reproducing information or a reproducing medium on the reproducing side, and thus preventing high speed dubbing of the reproducing information identified by discriminating information of which a clocking time has not elapsed. SOLUTION: Started high-speed-dubbing of music of a certain track, an MD recorder/player 1 detects an ISRC (an identifier peculiar to the track) of Q-channel data, and stores this IRSC in an IRSC management table 29 if the detected ISRC is not stored therein 29, and selects one unused timer from plural timers in a timer part 28 to activate it. When the timer has concluded a predetermined elapsed time, the MD recorder/player deletes the IRSC from the IRSC management table 29, and stops the high speed dubbing if he IRSC is already stored in the IRSC management table 29.

Title: Working method for enlarging diameter of thickness deviation steel tube
Inventor: HIROSHIGE ITSUROU
IPC: B21D41/02
Filed: 1989-03-29
Abstract: PURPOSE:To enlarge a diameter as large as necessary dimensions without concentrating strain on a thin thickness part and generating crack and contraction by working a thickness deviation steel tube with a semi-circular working claw on a thin thickness side and with plural working claws on a thick thickness side. CONSTITUTION:The diameter of the thickness deviation steel tube is enlarged with three working claws 2a, 2b, 2c. Since the thinnest part on te left side comes in contact with the working claw 2a and is constrained by friction, a small strain is generated in the steel tube. In this working example, six concentration parts of strain are found directly near the working and two concentrated parts of strain are found on the thickest thickness part. Since the strain of this thick thickness part supplies an elongation of the peripheral length of the steel tube necessary to enlarge the diameter, the elongation of the thin thickness part is reduced. When a single working claw is provided for the thin thickness side to enlarge the diameter, the strain is concentrated purposely only on the thick thickness part. In this way, the diameter can be enlarged without concentrating the strain on the thin thickness part and generating cracks and contraction.
