Title: Distance measuring system by use of laser beam
Inventor: OTA KAZUNARI
IPC: G01S7/48
Filed: 1991-04-25
Abstract: PURPOSE:To enhance the safety to the human eye without exceeding the max. tolerant exposure of an eye by setting the wavelength of laser beam to a specific wavelength or more. CONSTITUTION:The laser beam emitted from solid state laser 12 enters a five- time beam expander 15 to be emitted to the outside of the own car as beam with an expansion angle of about 0.5 mrad. A part of the laser beam applied to a target 16 to be scattered therefrom returns to the own car to reach a beam detection part 17. A pin photodiode of InGaAs is used in the beam detection part and a count part 18 measures the delay time from the emission of pulse beam to the detection thereof. By this method, the distance between the own car 10 and the target 16 is measured. At this time, for example, the oscillation wavelength of the laser 12 is 1.54mum and laser beam with a wavelength of 1.4mum or more is as high as four figures in the max. tolerant exposure of the eye to laser power intensity as compared with laser, beam with a wavelength of 1.4mum or less and far safe to an eye. Further, a Q switch element 13 is provided in the vicinity of the emitting end surface of the laser 12 and operated in connection with a pulse power supply 14 to generate narrow pulse high output beam to make it possible to measure a distance up to 300m.

IPC: F02B53/10
Filed: 1993-03-30
Abstract: PURPOSE:To decrease HC and CO through a process of stratrfying fuel, by forming, in the flank face of a rotor, the first and the second recesses to which the first and the second spark plugs face respectively by injecting the fuel at different timings in an intake process and by setting fuel lujoctine guontities in such a way as eqdolizing air-fuel ratios in respective recesses at nearly the same level. CONSTITUTION:The first and the second recesses 21, 22 are set in respective flank faces 2a of a rotor 2 at intervals in the rotation at direction in such a way as the first spark plug 11 and the second spark plug 12 face to those recesses at ignition timing. Shapes and volumes of both recesses 21, 22 are set as nearly same with each a ther. Fuel injection of a fuel injiction valve 13 is made to be carried out two times during one intake strokce and both fuel in jection quantites are made nearly equal to each other.

Title: Transmission type screen
Inventor: MORIGUCHI YUUTAROU
IPC: G03B21/62
Filed: 1981-06-20
Abstract: PURPOSE:To obtain a transmission type screen which is free of moir e fringes, by making the focal length of a lenticular lens less than the thickness of a light diffusing layer, and specifying the pitch of said lens within some range of plate thickness. CONSTITUTION:A transmission type screen 1 is formed of a semitransparent resin plate which contains a kneaded light diffusing agent; the focal length F of the lenticular lens 5 is 1/2-1/20 as great as plate thickness D, and the pitch P of the lens 5 is 1/4-1/40 as great as the plate thickness D. Consequently, the concentric Fresnel fringes of a Fresnel lens 2 are diffused completely by the light diffusing agent and then reach the respective focal points of the lenticular lens, so they never overlap with the lines of the lenticular lens. Thus, the generation of moir e fringes is prevented.

Title: Voltage-to-current converting circuit
Inventor: NAKAZAWA TAKATERU
IPC: H03F1/52
Filed: 1980-07-15
Abstract: PURPOSE:To protect an operational amplifier, by adding a transistor (TR) to the base of the TR that controls the current in order to apply the voltage when the operational amplifier has an overcurrent. CONSTITUTION:In case when the output current of an operational amplifier 1 increases owing to disconnection, etc. of an external load resistance 8, the base- emitter voltage of the 2nd TR12 increases to reach a certain value. Thus a sufficient biss is secured between the base and the emitter of the TR12 to turn on the TR12. As a result, a voltage VCC is applied to the base of the TR12 via a resistance 9, and accordingly a negative feedback is applied to the amplifier 1. Then the current is limited before the amplifier 1 has a saturation to reduce the loss of the amplifier 1.

Title: Semiconductor memory device having reflesh address test circuit
Inventor: KIYOU KIYOUU
IPC: G11C11/401
Filed: 1993-04-22
Abstract: PURPOSE: To provide a semiconductor memory device having a self refresh function for sensing the state of inner address signals used as refreshing and measuring refresh cycle time. CONSTITUTION: A refresh address test circuit 30 inputs the inner address signals 10 -Qn-1 generated in a refresh address counter 24 and outputs address test signals becoming a logic 'high' state when all the inner address signals Q0 -Qn-1 are in a logic 'high' state to a data output buffer 28. Since all the inner address signals become the logic 'high' state in the first period in the refresh cycle of a refresh clock ϕRFSH becoming the base of the inner address signals, the state of the inner address signals can be sensed by using the address test signal, and time required for self refreshing can be measured.

Title: Measuring device of high frequency electric power
Inventor: SHIRAI TADAO
IPC: G01R21/01
Filed: 1980-07-14
Abstract: PURPOSE:To measure electric powers of a wide range from low to high electric powers by providing a semiconductor amplitude limiter to a high frequency input terminal. CONSTITUTION:When an incident electric power is below the prescribed limit value of a semiconductor amplitude limiter 2, the high frequency electric power inputted to a waveguide 1 passes as it is through the limiter 2, and is inputted to the thermistor of a conversion part 3. The output of the part 3 is inputted to an incident high frequency electric power calculating part 4, and the high frequency electric power is displayed in a display part 5. On the other hand, when the incident electric power is in excess of the limit value, the limiter 2 limits the electric power incident to the part 3 and the limited electric power is proportional to the rectifying electric current 6 of a PIN diode 7. The sum of the value obtained by multiplying this current 6 by a conversion constant and the electric power past the limiter 2 is determined by the part 4, whereby the incident electric power is measured. Thereby, the burning of the thermistor due to the high electric power is prevented and the electric powers of a wide range are measured.

Title: Method and apparatus for continuously measuring shrinking ratio of cloth product in non-contact state
Inventor: MASSEN ROBERT
IPC: D06H3/08
Filed: 1985-05-08
Abstract: For the continuous contactless measurement of the shrinkage of textiles during the production process, the image of a portion of the textile surface is picked up both before and after the shrinkage and converted to analog electrical image signals by means of an image/signal transducer. The analog image signals are digitized by analog-digital converters and stored in image signal memories. A calculating unit determines from the stored digital image signals the periods of the textile structure both before and after the shrinkage in at least one evaluation direction, preferably in the longitudinal direction and in the transverse direction of the textile web. The change of length of the textile material in each evaluation direction is calculated from the ratio of the two periods determined in this direction. The method is in particular suitable for the measurement of the two-dimensional shrinkage of knitted textiles during the manufacturing process.

On the other hand, another air diffusing member 20 for jetting air out only at the time of backward washing the lower carried bed 30 is disposed in the lower part of the bed 30. At the time of performing the normal operation, the make-up SS is supplied without shaking the granular carrier 16 of the lower carrier bed 30.  Further, a treated water tank 12 having a larger volume than the volume of the lower carrier bed 30 is placed at a higher level than that of the boundary section 31 between the carrier beds 29 and 30. Thus, the lower carrier bed 30 can sufficiently be washed backward without lowering the water level of the biological filtration vessel 10 to the level of the boundary section 31 or below.
