Title: Angle regulating device for body crack grain detector
Inventor: SATAKE TOSHIHIKO
IPC: G01N33/10
Filed: 1981-07-02
Abstract: PURPOSE:To enable cereals to stably run in a longitudinal running manner, by a method wherein an inclined cereals gutter 9 is rotatably mounted to a securing leg, and an inclining angle regulator is installed at the under side of the gutter. CONSTITUTION:An inclined cereals gutter 9 is pivotably secured to a securing leg 15 through a rotary axis 16, and an angle regulator 18 is coupled to the under side part thereof. If, through turning of the screw of the regulator 18, the gutter is regulated into an inclining angle corresponding to raw rice grains, the rice grains, accurately aligned in a longitudinal running menner, run down stably, and only crack grains are detected according to brightness by means of a light source 11 and a collecting device 11. This adjusts an angle corresponding to a change in the shape of cereals, coarseness of cereal surface, moisture content, and permits the cereals to run smoothly.

Title: Truck for rolling stock
Inventor: SEKINO AKIRA
IPC: B61F5/40
Filed: 1987-04-30
Abstract: PURPOSE:To enable smooth running on a curved railroad section without requiring special operation by controlling the length of a hydraulic cylinder through detection of vehicle speed and vehicle side ground point thereby controlling inclination of front and rear wheels in back/forth direction according to the curvature of the railroad. CONSTITUTION:Upon approach to a curved railroad section, electrical signals are fed from ground point detectors 24, 25 at vehicle side and ground side to a controller 23 which provides an electrical signal immediately to a hydraulic pressure distribution valve 21. At this time, an electrical signal is also fed from a speed detector 32 to the controller 23. Upon function of the hydraulic pressure distribution valve 21, hydraulic pressure is fed or returned to/from hydraulic cylinders 10, 11, 12, 13. Feeding/returning quantity of oil is regulated previously by means of a memory circuit in the controller 23. Front and rear axles 1, 2 can be inclined according to the curvature of railroad by varying the length of the hydraulic cylinders 10, 11, 12, 13, and thereby an operator can pass the curved railroad section smoothly without requiring special operation.

Title: Semiconductor laser and its manufacture
Inventor: MORI YOSHIHIRO
IPC: H01S5/00
Filed: 1992-04-23
Abstract: PURPOSE:To maintain a fundamental-mode oscillation up to a high optical output and to enhance the surge breakdown strength of the title laser. CONSTITUTION:The title laser is provided with the following: a p-type clad layer 104 provided with a protruding part which is extended to be a stripe shape in the central part; a barrier-reducing layer 108 formed on the protruding part; a current-blocking layer 106 formed in such a way that the end part of the barrier-reducing layer 108 and the p-type clad layer 104 are covered with it; and conductive layers 109, 110 with which they are covered. The width in which the conductive layer 109 comes into contact with the barrier-reducing layer 108 is made narrower than the width of the barrier-reducing layer 108 so that an electric current is gathered in the center. Thereby, a fundamental mode can be maintained up to a high current value. In addition, since the propagation loss of the primary mode of the title laser is large and the optical output of the title laser is lowered when the title laser is shifted to the mode, a current value which reaches the optical output which causes its instantaneous optical damage becomes large and the title laser becomes resistant to a surge.

Title: Ti brazing material
Inventor: SHIBATA TOMOKI
IPC: B23K35/40
Filed: 1987-04-30
Abstract: PURPOSE:To simplify the operability at brazing time with low m.p. by forming the title material in a band like or linear shape with a liquid rapidly cooling solidification method by composing of the specified composition. CONSTITUTION:What is composed of 20atom.% max. Cu, 30atom.% max. Ni, 35atom.% max. Zr and the balance Ti and inevitable impurities is formed in a band like or linear shape by a liquid rapid cooling solidification method as a Ti brazing material. With respect to the limitation of the composition Cu is an effective element for reducing the m.p., but the affinity with a base metal is reduced as well in the case of its being beyond the specification. Ni also reduces the m.p., but its affinity with a base metal is reduced as well. Zr also reduces the m.p. but brings about the embrittlement of a base metal at the time when it becomes beyond the specified. The balance Ti is for approximating the characteristic of the joining part to that of the base metal especially at the brazing junction of Ti and Ti alloy becoming of the base metal.

Abstract: PURPOSE:To obtain a resistance section which is accurately formed by a method wherein a resistance section forming region is formed on a layer which is different from a substrate in an etching property and thereafter etching is performed from the rear. CONSTITUTION:A resistance section forming region 2 is formed on a layer 5 which is different from a substrate 1 in an etching property and the part of the other main surface corresponding to the resistance section forming region 2 is subjected to etching as far as the layer 5 different in a etching property so as to form a resistance section 11. In such a manner as mentioned above, the resistance section 11 is formed on the layer 5 different in an etching property, wherefore the resistance section 11 can be controlled in thickness at the point of time when a semiconductor layer 6 to be the resistance section 11 is formed. Therefore, a etching itself does not need to be controlled as the etching is performed and the resistance section 11 with a required thickness can be obtained which is formed on the layer 5 different in an etching property.

IPC: G01S7/40
Filed: 1981-07-06
Abstract: PURPOSE:To detect and monitor drop in the level of beat signals at a high accuracy and a high speed at an interval of a fixed period by digital measurement to determine whether or not there is any missing among pulses in the waveform shaping of beat signals. CONSTITUTION:Beat signals received by a transmitter/receiver section 1 are turned to pulse signals with a waveform shaping circuit 2 which controls the opening of an AND gate 6 to which cloks are applied from a clock oscillator 5. Then, the clocks via the gate 6 are counted with a counter 4 in which a fixed counting period is controlled with a processor 7. Then, the processor 7 discriminates missed pulses depending on whether the count from the counter 4 corresponding to the sum of the shaped pulse width periods for a fixed period is larger than one-half of clock count for the fixed period to detect and monitor the level of beat signals. Such digital measurement and the discrimination enables a highly accurate, fast detection of a drop in the level of beat signals at an interval of a fixed period.
