Title: Self-compensating method for offset voltage of hall element
Inventor: SHINDO BUICHI
IPC: H01L43/06
Filed: 1989-02-03
Abstract: PURPOSE:To correct the change in offset voltage of Hall elements with time by using a combination of Hall elements on the same semiconductor substrate to remove the offset voltage which is not dependent on a magnetic field. CONSTITUTION:Two square Hall elements 101, 102 having the same structure and area are prepared, and manufactured to be to disposed on the same semiconductor substrate that an angle of driving current axial directions is set to 90 degrees. Then, the output signals of the elements 101, 102 are amplified by primary amplifiers 108, 109 for inversely amplifying at one side and non- inversely amplifying at the other by the same gain, and the output signals of the amplifiers 108, 109 are further amplified by a differential amplifier 112. An electric circuit is so operated as to cancel a piezo resistance effect of the cause of age-change of the offset voltage of the element 101 by that of a compensating element 102 disposed near the element 101. Thus, the circuit output when a magnetic field is acted on the Hall element can be output as an output signal depending only on a magnetic filed from which the offset voltage component is removed, thereby always performing a self-compensating operation against age-change of the offset voltage.

Title: Partition structure for smoke protection
Inventor: OTANI SHIGERU
IPC: A62C2/06
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To delay the invasion of smoke to prevent generation of a section surrounded by smoke by making protruding amounts of dangling walls to partition a section important for guiding evacuees and orderly decreasing protruding amounts of the dangling walls as becoming more distant. SOLUTION: Dangling walls 41-47 are classified into three kinds of protruding amounts H1-H3, which are H1<H2<H3, and H1 is a value not lower than a legal regulation (50 cm). When a fire broke out at a section 50 to generate a large amount of smoke over a smoke eliminating capacity, smoke fills under the ceiling face of the section 50. When the thickness of the smoke came over H1, the smoke comes under the dangling wall 42 to diffuse in a section 48. When the thickness of the smoke in the section 48 over H1, the smoke comes under the lower dangling wall 41 in the section 48 to diffuse in a section 49. When the thickness in sections 50, 48 and 49 came over H2, the smoke diffuses in the section 51 and 52. When the thickness of the smoke in the sections 48-52 came over H3, the smoke comes under the dangling walls 46 and 47 to diffuse in the last section 53. All the building is filled with the smoke at last.

Filed: 1980-03-03
Abstract: PURPOSE: To check the power source voltage, which is applied to the device related to voice synthesis, for abnormality, by using the information control means in the voice synthesizing control device.  
     CONSTITUTION: For example, an electronic desk calculator consists of microprocessor MPU, key input device KEY, and display device DISP, and voice synthesizing controller VC, D/A converter D/A, amplifier AMP, and speaker SP are connected to this calculator, and entry contents input from keys and operation results are output with voice. For voice output, output terminal R 2  of MPU is made H, and the power source of VC is turned on. Since the ACL signal of the reset signal is H normally, VC is reset. When ACL is set to L after a prescribed time, VC executes instructions which are stored preliminarily, and output terminal CO8 is made H first. In case of abnormality, CO8 is L still, and this signal is monitored to detect the abnormality of the power source of VC.

Abstract: PURPOSE:To obtain a always good tracking state even with a recording medium on which control signals are dropped out or are not recorded for a long period of time by stabilizing the traveling of the recording medium by using the control signals reproduced from the recording medium. CONSTITUTION:An arithmetic processing means 17 which detects the amplitude of the reproducing signals by rotary heads 2, 3 and generates the control signal for enhancing the amplitude, a control signal detecting means 11 which detects the absence of the reproduction of the control signals from the recording medium 1 for a long period of time and a speed control means 21 which controls of the speed of a capstan motor 5 according to the control signals outputted from the arithmetic processing means 17 are provided. The amplitude of the reproducing signals falls successively when the control signals are not reproduced for a long period of time from the recording medium 1. The arithmetic processing means 17 monitors a change in the amplitude of the reproducing signals and changes the rotating speed of the capstan motor 5 in an opposite direction by outputting the control signal when this amplitude decreases. The scanning state of the rotary head is brought to the optimum tracking state in this way.

Abstract: PURPOSE:To attain A/D conversion without using an analog delay circuit by obtaining a difference between an output of a D/A converter and an input analog signal at a point of time after the elapsed processing time of the D/A converter with a differential amplifier circuit. CONSTITUTION:Since a differential amplifier circuit 23 obtains a difference between an output of a D/A converter 22 and an input analog signal SA at a point of time after the elapsed processing time of the D/A converter 22, the input analog signal SA is supplied to the differential amplifier circuit 28 without a delay. Then an arithmetic processing circuit 29 synthesizes (adds) the difference di to an output Di of a 1st D/A converter 21. Thus, no analog signal delay line is required, a large space is not required and the size of the entire converter is reduced.

CONSTITUTION: A first bead 24 is piled/deposited along a pattern A on a rim 16 of a base body. While sufficient heat is transmitted to the rim 16 and a surface of a base body material is fused in some extent, most of a bead 24 material is fused up to reaching the base body. fused materials are mutually mixed with each other and are rapidly solidified. Thus, the first bead 24 is fused to the rim 16 to form an integrated overlay. Successively, a second pass to deposit a second bead 26 is conducted. In the second pass, the bead follows the pattern of a next cross section above the cross section A. The second bead 26 is fused in the first bead thereunder to form integrated structure. This procedure is repeated until the bead height as a whole is formed. By depositing the beads following the pattern measured beforehand, the blade is precisely reproduced.
