IPC: H01L21/027
Filed: 1983-03-07
Abstract: PURPOSE:To increase the accuracy in position detection by a method wherein, when a positioning mark is provided on a sample being a substrate, it is formed in groove shape, and the ratio of said mark step value and an aperture is set at approximately 0.5, thereby enabling to obtain a composite signal of an increasing signal and a decreasing signal by two detectors provided on the mark. CONSTITUTION:A positioning mark consisting of a groove 18 having the ratio of a step value and an aperture of approximately 0.5 is formed at the beam incident posiion of the sample which is a substrate. Then the signal, obtained by scanning a beam on the bottom faces 5 and 6, and 7 and 8 of the groove 18 is made to be incident on the detectors 1 and 2 respectively. According to this constitution, the detectors 1 and 2 are placed with their back sides facing each other, the point of the signal made to be incident on the detector 2 is formed into sharp protruded shape 10 on the end side 4, and it has recessed shape 12 on the end side 9. On the contrary, the signal which is made to be incident on the detector 1 is formed into recess shape 15, while being formed into protruded shape 17, thereby enabling to obtain a detecting signal of large intensity in the synthesized form.

IPC: H01J35/06
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To provide an X-ray tube whose dimension and weight can be reduced and thermal performance can be improved and the ratio of performance to a dimension can be maximized. SOLUTION: An X-ray tube 10 contains an anode assembly 12 and a cathode assembly 16 positioned in mutually juxtaposed arrangement. An anode rotor 28 is reversed to an ordinary orientation, and operates by grounding electric potential.

Title: Method of fabricating gallium phosphide light emitting display element
Inventor: HISATOMI KIYOSHI
IPC: H01L21/306
Filed: 1979-03-29
Abstract: PURPOSE: To improve the light emitting efficiency of a gallium phosphide light emitting display element by cutting and cleaning a GaP wafer formed with pn junction, and dipping it in a mixture solution of 12 code hydrochloric acid and 30% by weight of hydrogen peroxide at 1:10∼30.  
     CONSTITUTION: A pn junction is formed, electrodes are attached to a GaP wafer, and the wafer is cut into unit pellets. Then, the wafers are contaminated with cutting chips or the like, and clead with acetone or the like. However, the external quantum efficiency of the surface of the pellet is remarkably decreased to lower the light emitting efficiency. Then, the pellet is dipped in a mixture solution of 12 code of hydrochloric acid and 30% by weight of hydrogen peroxide at 1:10∼30, rinsed with water, and dried. Then, the pellet is removed from the pulverized layer to improve the litht emitting efficiency. When the ratio of the hydrogen peroxide to the hydrochloric acid is less than 10, the efficiency becomes rough, and when it is higher than 30, the efficiency is insufficient.

Title: Method and apparatus for measuring electric signal
Inventor: MITOME MASANORI
IPC: G01N37/00
Filed: 1994-02-09
Abstract: PURPOSE:To easily measure a second order partial differential coefficient regarding a plurality of variables by adding modulation signals having different frequencies to dependent variables of a signal to be measured and by multiplying obtained signals by an alternate signal of frequencies equivalent to a difference or sum of two modulation signals. CONSTITUTION:A signal to be measured entering from an input terminal 1 enters an adder 6 after extra oscillating components are filtered off. A rectangular wave having a frequency equivalent to a difference or sum of frequencies of two modulation signals created by a rectangular wave generating circuit 5 enters the adder 6 and multiplied by a signal to be measured that is the output of the filter 4. As a result of multiplication, a signal outputted from the adder 6 can be regarded as the sum of a dc signal and an ac signal. The do signal is proportional to a second order partial differential coefficient and is therefore passed through a low-frequency pass filter 7 and amplified by time average, thereby selectively amplifying the second order partial differential coefficient.

Title: Pedal displacement controlling structure for vehicle
Inventor: NOTAKE JIRO
IPC: B60T7/06
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To control displacement of a pedal tread face for a vehicle when external force above the predetermined value is applied from the front side of the vehicle. SOLUTION: The rear end of a pedal bracket 26 and a mounting bracket 64 are connected together removably, and the connecting face between them is tilted toward the vehicle lower side substantially at a predetermined angle to the horizontal face. In addition, a tilting plate 76 tilting toward the vehicle width directional outside substantially is arranged on the rear side of the pedal bracket 26 toward the vehicle rear side substantially.  Therefore, the rear end part of the pedal bracket 26 is removed from the mounting bracket 64 because of the structure of the pedal bracket 26 when external force above the predetermined value is applied from the front side of a vehicle, and at the same time, rotational force to the substantially vehicle front side is applied to the rear end side of the pedal bracket 26, and sideward displacing force toward the vehicle width direction outside is applied to the rear end side because of the structure of the mounting bracket 64. In this way, the pedal pad can be controlled so as to be displaced toward the substantially vehicle front side and the substantially vehicle width directional outside.

Abstract: PURPOSE:To prevent an open sunroof from being closed except when necessary by providing a control means having a sunroof closing control function whereby it inhibits the closure of the sunroof when detecting that a sunroof switch has been operated to select the closure of the sunroof while a power window is being locked. CONSTITUTION:If a sunroof switch is operated to open or close a sunroof while a window lock switch is on (a normally closed contact 32 being open), a contact 37 comes into contact with a terminal 35 or 36 and the terminal 16a of a sunroof controller enters into a Hi state', then the sunroof controller 16 determines that the window lock switch is on, and permits a sunroof motor 20 to carry current only in a direction for opening the sunroof. Then the motor- driven sunroof is drivingly opened but kept from being drivingly closed. Such a control function enables the driver to avoid the unnecessary job of closing against his will the motor-driven sunroof in the open position.
