Title: Displacement measuring device
Inventor: OSHIDA YOSHISADA
IPC: G01D5/38
Filed: 1981-06-17
Abstract: PURPOSE:To measure displacement of an object to be measured, with high accuracy,  by dividing a light beam emitted from a light source having interferability, into two  beams, and deriving a variation of interference light intensity in case when the travelling directions of diffraction light beams obtained by irradiating said divided beams to the same spot of a grating from different directions have been made the same. CONSTITUTION:A beam emitted from a laser light source 1 having interferability is  divided into two beams by a beam splitter 2, and these light beams are irradiated on a  grating 41 by light beam reflectors 31, 32. Subsequently, interference intensity of diffraction light of two diffracted light beams is detected, and in accordance with an  electric signal converted to the electric signal by an optical detector 5, the extent of  displacement of the grating 41 is derived by a signal processing circuit 6. The travelling directions of the two diffracted light beams which are diffracted by the grating 41  and are made incident to the optical detector 5 are made the same, and also displacement of an object whose displacement is to be measured is made the same as displacement of the grating 41 by moving the grating 41 in the vertical direction against stripes of the grating 41, so that displacement of the object to be measured can be measured from a variation of interference light intensity of the two diffracted light beams.

Title: Method and apparatus for abrasion test
Inventor: OOMORI SHIYUNJI
IPC: G01N3/56
Filed: 1981-06-16
Abstract: PURPOSE:To achieve abrasion test free from effect of wear dust with the duplication of a heat cycle by turning a test piece placed on the outer surface of one of two cylinders parallel to each other in the axis which are made movable longitudinally and laterally in a relative manner. CONSTITUTION:The temperature of a material model 1 is measured with a radiation thermometer 18 once it is heated with a high frequency heating coil 17 to coincide with the temperature during forging. A table 12 is moved by the operation of a handle 13 so that a die model 19 mounted on a disc 9 parallel in the axis to the material model 1 comes close to and contacts the material model 1. The sum of the peripheral velocities V1 and V2 of the material model 1 and the die model 19 matches the slide speed during the forging by controlling motors 8 and 11. The handle 13 is operated to reach coincidence between the contact time between both models and the actual working time and the table 12 is moved so axially by a motor 15 that the surface of the material model 1 without groove will always rub the die model 19. In this manner, the abrasion test is performed.

Title: Photometer for single-lens reflex camera
Inventor: YANAI YUKIHITO
IPC: G03B7/099
Filed: 1988-04-15
Abstract: PURPOSE:To provide a single-lens reflex camera with a photometer capable of eliminating the influence of outside light made incident from a finder side by performing a non-reflection treatment on the lower surface of a beam splitter plate and on the end surface opposite to a light receiving element with respect to a half mirror in the beam splitter plate. CONSTITUTION:A photographing beam A which is transmitted through a photographing lens 1 reflects on a mirror 2 and passes through the beam splitter plate 3, and then forms an image on the focal plane 5 of a finder. A part of the beam reflects on the half mirror 6 and makes incident on the light receiving element 7 to measure the brightness of an object. The lower surface 3a of the beam splitter plate 3 is subjected to the non-reflection treatment with a multi-layer film. The end surface 3b opposite to the light receiving element 7 with respect to the half mirror 6, is ground and subjected to the non-reflection treatment with a mat black coating. As a result, even when the outside light B makes incident on the beam splitter plate 3 from the finder side through the focal plane 5, the intensity of the outside light which makes incident on the light receiving element 7 is very weak and the influence thereof can be ignored. By this means, the brightness of an object can be measured accurately.

Title: Video recording system
Inventor: TAKAHARA YASUAKI
IPC: H04N5/225
Filed: 1988-04-18
Abstract: PURPOSE:To avoid crosstalk by detecting a crosstalk caused in a radio signal and switching a reception frequency or a transmission frequency in a video camera and a video recorder sending a video signal in a radio signal. CONSTITUTION:When a video recorder 2 detects a crosstalk in a reception signal of a channel ch1, a crosstalk detection signal is brought into an H level and a channel revision command is sent. When a video camera 1 receiving it switches the transmission frequency from the channel ch1 into a channel ch2. The recorder 2 detects the missing of the reception signal of the ch1, brings the level detection signal 2e into an L level and switches the reception frequency from the ch1 into the ch2. Then the recording signal 2g is switched into a recovered synchronizing signal 2d till the reception signal appears on the ch2 and it is recorded. When the reception signal level rises, the level of the signal 2e goes to an H level and the signal is switched into the signal demodulating the reception signal. Thus, the disturbance of the picture due to crosstalk is avoided.

IPC: B07B13/18
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To enable the selection between the efficiency partition control and high precision partition control of a brown rice partitioning plate. SOLUTION: A moving unhulled-brown rice discrimination sensor 30 detects the selection condition on the discharge side of an oscillating selection plate 15 to control the partition position of a brown rice partitioning plate 18. When the partition control of the plate 18 is shifted to the side of ordinary precision, by the first detection of the boundary position between unhulled rice and brown rice by the sensor 30, the boundary detection is judged to be completed, the partitioning plate 18 is moved to the partition position related to the boundary position. When the control of the plate 18 is shifted to the side of high precision partition, the boundary detection is not judged until a prescribed number of the boundary detections being carried out by the sensor 30 at a prescribed position, and the plate 18 is moved to a related partition position.  In this way, when high precision partition is selected, since the plate 18 is moved in relation to a prescribed number of the boundary position detections by the sensor 30, high precision brown rice partition selection can be performed, preventing the contamination of unhulled rice into brown rice.

Title: Method of detecting signal element of periodic square wave signal and its circuit
Inventor: NORUBERUTO FUOORUMAIRU
IPC: G01D5/246
Filed: 1982-06-03
Abstract: A method and apparatus for determining the phase angle between two periodic square wave signals is disclosed in which the two square wave signals are applied to respective inputs of an exclusive OR gate, the output signal of which is applied to a first input of a digital selection circuit. The output signal generated by this digital selection circuit is passed through a low pass filter to form a time integral, arithmetic mean value which is digitized by an analog to digital converter and supplied as a numerical value to a digital computer. The digital computer applies logical signals to two additional inputs of the digital selection circuit. The computer is programmed to sequentially set these control signals such that the digital signal presented to the computer sequentially represents the mean value, an upper signal level value, and a lower signal level value of the square wave signal output by the selection circuit. The computer is programmed to use these three variables to calculate a corrected value of the phase angle and to display this calculated value on a display unit.
