Title: Manufacture of horizontal pn junction array of semiconductor element
Inventor: BIN SEKIKI
IPC: H01L31/04
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To allow existence of a PN junction part on the surface and arrival of incident light on the junction part with no loss by injecting a small amount of specific gas on a substrate with V-shaped grooves so as to grow P-type GaAs or P-type AlGaAs only in these grooves for forming a PN junction array in the horizontal direction. SOLUTION: A V-shaped or U-shaped grooves are formed on a sample piece in which an N-type GaAs epitaxial layer with a 2 to 3μm thickness is made to grow on a seminsulating GaAs substrate. Next, a GaAs epitaxial layer is made to grow on a sample piece, in which these V-shaped or U-shaped grooves are formed, while adding CCL4 or CBr4 gas by performing an MOCVD method. Thereby, when this gas is added, growth is sharply increased in the horizontal direction of the side, further, since carbon C added at this time acts as a P-type dopant, it becomes P-type GaAs or P-type AlGaAs so as to form a PN junction array structure in the horizontal direction. Therefore, loss of light is prevented so as to improve efficiency of a photoelectric element.

IPC: H04N5/52
Filed: 1979-02-15
Abstract: PURPOSE:To avoid occurrence of the excessive output by cutting off the AGC loop to the pulse-type noise to secure increment of the AGC time constant and then decreasing contrarily the AGC time constant apparently to the arrival of the excessive signal to secure the immediate countermeasure to the excessive signal respectively. CONSTITUTION:When the pulse-type noise mixes into the signal and the noise level is at the fixed value, transistors TrQ4 and Q2 are turned on with TrQ5 and Q3 are turned on with TrQ5 and Q3 turned off respectively. With TrQ5 turned off, and accordingly TrQ6 is turned off. Thus the route is cut off between AGC detection amplifier 29 and AGC time constant circuit 32, and then the AGC loop is cut off. On the other hand, noise detection circuit 30 detects the noise and then turns TrQ7 on. And TrQ10 is on since excessive signal detection circuit 31 has no operation. As a result, TrQ11 is turned on with the time constant increased for circuit 32. When the excessive signal arrives, Q9 of circuit 31 is turned on. Then the charge of capacitor 43 is discharged via TrQ4 and Q9.

Title: Strength measurement of abrasive grain
Inventor: UIRIAMU JII MORISU
IPC: G01N3/34
Filed: 1994-02-10
Abstract: PURPOSE: To enable individual grain strengths to be measured speedily and precisely by inserting a grain of hard material into the clearance between both rollers and compressing the grain until it is broken. CONSTITUTION: A material of rollers 10 and 20 has a hardness of 8 or more in Morse's scale and is preferably made of tungsten carbide. The roller 10 is fixed to a frame 80 rotatably, and the roller 20 is attached to a beam 30. When a screw of a clearance regulation member 50 is turned, the side of a clearance 90 between the rollers can be changed so as to accept the grains of various sizes. Motion in the direction of the clearance 90 of the roller 20 is measured by means of a proper transducer 70 such as a linear voltage difference transformer. The output of this transducer 70 is an electric signal, that voltage is proportional to the deflection of the roller 20, therefore, it is proportional to the compression force applied to grains. When this compression force reaches a level beyond the strength of grains, the grains are broken.  The compression force at this peak is stored or processed by means of the computer.

Title: Air trap structure in ink jet apparatus
Inventor: YAMAZAKI HIROSHI
IPC: B41J2/175
Filed: 1985-01-30
Abstract: PURPOSE:To make it possible to effectively perform the trapping of air bubbles, by providing a mesh filter in the vicinity of the inflow passage of an air trap chamber so that an inflow stream line bypasses upwardly to be directed to an outflow passage. CONSTITUTION:In order to perform the trapping of air bubbles in a limited dimension and shape, filters are arranged to an inlet and an outlet and the filter at the inlet is arranged so as to extend along an inflow stream line as possible. Because the stream line advances along the filter, minute air bubbles are adhered and accumulated to the filter by the slight collision force with the filter to be grown to large air bubbles. Because of this, sufficient floating force and air bubbles are not drifted by flow and float by themselves and can be collected to enable the effective trapping of air bubbles. The filter 12 is set to a mesh finer than that of the filter 11 so that no air bubbles pass through the filter 12 even if colliding against said filter 12.

Abstract: PURPOSE:To reduce an erroneous operation due to a noise by detecting an output voltage by a pulse width controller, comparing it with a reference value, generating a binary signal, and controlling a converter through a driver on the basis of the result. CONSTITUTION:A digital pulse width controller 13 of a power source 10 detects an output voltage V0, compares it with an inner reference voltage, and produces binary signals A1, A2 for driving a driver 12 on the basis of the result. The driver 12 receives the signals A1, A2 and produces pulses B1, B2 for directly driving a converter 11. The converter 11 generates a power pulse of a DE input V1 by the pulses B1, B2, rectifies and smoothes it and produces a stabilized DC output V0. Thus, the controller is digitized to prevent an erroneous operation due to a noise.
