Abstract: PURPOSE:To reduce a high-density dislocations remaining in an SOI(silicon-on- insulator) layer by depositing an amorphous silicon layer on an insulating layer having an opening, solid growing the silicon layer, then reducing in thickness the grown layer by etching and annealing it. CONSTITUTION:An Si substrate is thermally oxidized to form an insulating layer 2. A linear opening 3 is provided in the layer 2 to expose a surface of an Si substrate 1. Then, an a-Si layer 4 having a thickness of 1.5mum is deposited on the layer 2 by thermal decomposition of disilane (Si2H6). Thereafter, the layer 4 is annealed for solid-phase growth. Then, the grown layer (single-crystal semiconductor) 5 is reduced in thickness by etching. It is annealed at 1050 deg.C for one hour in an electric furnace. Thus, an SOI layer having high crystallinity can be obtained in a wide region.

Title: Serial dot printer
Inventor: KAWANO REIJIROU
IPC: G06K15/08
Filed: 1978-12-26
Abstract: PURPOSE: To vary a print speed, etc., without causing a trouble due to a change in temperature, by detecting the change in temperature of an element driving part.  
     CONSTITUTION: Print information is temporarily stored in line buffer LB and drives electromagnet MGN as a printing element driving part through electromagnet driver circuit MND. Instead of the internal temperature of the driving part, an enclosure temperature is measured by a thermocouple and detected by temperature detector TM to calculate a difference between the temperature and a reference operating temperature, and a new value with a driving period made slow is obtained by driving period selector circuit DPS from the difference. Then, motor-speed calculation circuit MSC finds a motor speed corresponding to the value selected by DPS to turn motor SM through motor driver circuit SMD. Then, a signal obtained by speed detector SCH composed of a rotary disk with slits and an optical detector reaches MND as printing-element driving timing. Consequently, the printing-element driving period becomes slow and the mean value of a driving current lowers.

Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To provide a speed measuring apparatus by which the speed of a club head during the swing of a golf club can be measured simply without selecting a place. SOLUTION: A small rotor 4, a small generator 6, a small current recorder 7 and an outer frame case 1 constitute a small speed measuring apparatus. The speed measuring apparatus can be placed on the club head part of a golf club. Accordingly, a wind pressure is developed in the speed measuring apparatus so as to be proportional to the speed of the swing of the golf club. The air flows into the speed measuring apparatus so as to be proportional to the wind pressure. The rotor 4 is turned at a rotational speed which is proportional to the quantity of the air which flows into. Electricity which is proportional to the rotational speed of the rotor 4 is generated. When a numerical value obtained by measuring the magnitude of the quantity of the generated electricity is corrected, the speed is measured.  In this manner, since the apparatus itself is made small so as to be capable of being placed on a moving object or a moving living body, the speed of the moving object or the moving living body can be measured.

IPC: G06K9/00
Filed: 1989-06-27
Abstract: PURPOSE:To obtain a clear finger picture by increasing the height of a finger setting surface of a finger setting stage compared with the attachment surface of the finger setting stage. CONSTITUTION:The surface (finger setting surface T) of a prism 12 is protruded over the upper surface (attachment surface) of a housing 11. Thus a finger F can be easily set on the prism 12. In other words, the even force can be applied onto the entire finger F. As a result, the pressing force of the finger F is never scattered up to the upper surface of the housing 11. Thus the finger F can be entirely and surely set close to the surface T of the prism 12. Then a clear finger picture is obtained.

Abstract: PROBLEM TO BE SOLVED: To realize high precise angling even in bending of an obtuse angle or even though a main body frame of a press brake is elongated by a change in environmental temperature. SOLUTION: Bending loads in plural places in the longitudinal direction of a movable table 11 are detected with a bending load detecting device 31 at the time of trial bending with a press brake, and a displacing quantity of the movable table 11 is detected with displacing quantity detecting devices 25, 27. The total sum value of a work load consisting of the product of the bending load multiplied by the displacing quantity in plural places in the longitudinal direction of the movable table 11 is calculated as a target work load with a controller 35.  A tilting quantity of the movable table 11 is adjusted by means of a tilting quantity adjusting device 23 with the controller 35 so that the total sum value of the work load when bending a product reaches the target work load, whereby the displacing quantity is adjusted, and a deflecting quantity of the movable table 11 is adjusted with a crowning correcting device 29. Since an actual work load is made to be an object of control, high repeating precision is obtained using the trial bending angle as a reference.
