Title: Dislocation reducing layer
Inventor: NISHIMURA TAKASHI
IPC: H01L21/20
Filed: 1988-05-07
Abstract: PURPOSE:To enable a crystal where no new dislocation and cross hatch are generated between the surface-nearest layer and dislocation-reducing layer by gradually reducing the grid constant difference between the compound semiconductor layer and the semiconductor layer toward the surface-nearest layer. CONSTITUTION:Dislocation of a GaAs layer 2 of approximately 2mum grown on an Si substrate 1 is reduced by annealing. By gradually reducing the composition ration x of In, an InxGa1-xAs layer 3 and GaAs layer 4 are alternately grown. By making the composition ration x of In at the interface between a GaAs layer 2 and an InxGa1-xAs layer 3 to be sufficiently large, propagation dislocation from below can be sufficiently bent. Also, by reducing the deviation of lattice while setting the composition ratio of In at the interface between the surface-nearest GaAs layer 5 and the InxGa1-xAs layer 3, no new dislocation or cross hatch homology are generated. It allows an improved GaAs layer 5 to be obtained.

Abstract: PURPOSE:To enhance measuring accuracy to a large extent, in measuring the concn. of hydrogen, by performing the correction of hygroscopic moisture due to the concn. of steam in a reactor container and the correction of pressure due to the concn. of steam in the reactor container. CONSTITUTION:A steam concn. signal 40 showing the concn. of steam in a reactor container (PCV) 1 is inputted to a steam concn. correction circuit 9 and the detection signal 8 is corrected to a value wherein the effect of the concn. of steam in a sample gas is excluded. This correction signal 10 is supplied to a pressure correction circuit 11. The PCV pressure signal 42 showing the pressure in the PCV 1 is inputted to the pressure correction circuit 11 and the correction signal 10 is corrected to a value wherein the effect of the pressure in the PCV 1 is excluded. The steam concn. signal 12 obtained by correction is transmitted to a meter 13 to be displayed as the concn. of steam. Further, when the set temp. of a thermostat 7 is set to constant temp. of about 180 deg.C, the temp. change around a hydrogen detector is reduced even in the case of an imaginary accident and the concn. of hydrogen can be always measured with high accuracy.

Title: Pid controller of sample value
Inventor: ICHIKAWA YOSHINORI
IPC: G05B13/00
Filed: 1983-06-22
Abstract: PURPOSE:To respond quickly to a change of a target value and to suppress a disturbance by using a PID control constant and a sample period to design a filter constant and using this filter constant to perform correction with a target value filter. CONSTITUTION:A sample value control constant arithmetic part 11 uses denominator parameters g0-g3 of the transfer function, which are calculated in a transfer function arithmetic part 10, and a sample tau period to calculate a sample value PID control constant. A filter constant arithmetic part 13 calculates target value filter constants h1-h3 in accordance with PID control contants Ti and Td and the period tau. When a sample value PID controller is started initially, constants h10-h30 which are calculated on the basis of initially set PID control constants Ti0 and Td0 and the period tau are set to a target value filter 12 through a switch 18. After identification is terminated, constants h1-h3 are set to the filter through the switch 18. The filter 12 uses filter constants, which are designed in this manner, to perform arithmetic and correction at intervals of the period tau.

Title: Light wave level meter
Inventor: YOSHIDA TAKASHI
IPC: G01S7/48
Filed: 1985-05-23
Abstract: PURPOSE:To restrain the occurrence of a fault and increase the accuracy of a level measurement by providing a transparent member in an oblique direction with respect to the direction of the optical axis of a light wave emitted from a light receiving portion through a lens so as to shield the direction of the optical axis. CONSTITUTION:A light wave emitted from a light receiving and transmitting portion 13 and converted to a parallel light by a lens 15 passes through a transparent member 19 and, at the same time, a part of the light wave is reflected by the transparent member 19. At this time, since the transparent member 19 is provided in an oblique direction with respect to the optical axis of the light wave 30 emitted from the light receiving and transmitting portion 13, a reflected light 31 from the transparent member 19 is directed in a direction deviated from the light receiving and transmitting portion 13. Therefore, this reflected light 31 does not affect another reflected light that is returned to the light receiving and transmitting portion 13 after transmitted through the transparent member 19 and reflected by a liquid surface. Further, since the light receiving and transmitting portion 13 and the like are hermetically sealed by a level meter body 14 and the transparent member 19, a fault can be restrained and a measuring accuracy can be increased.

Title: Information recorder
Inventor: IDEI TOSHIO
IPC: G11B7/09
Filed: 1994-05-25
Abstract: PURPOSE:To stabilize the recording operation by successively measuring lengths of the period of a reproducing beam and the periods corresponding to strong/ weak two kinds of respective beams at a recording time, performing sample-and- hold when the lengths are longer than a prescribed period and obtaining a servo signal and a laser power signal stable even in a high speed operation. CONSTITUTION:A sample-and-hold propriety decision circuit 37 outputs a decision signal showing the decision result of sample-and-hold propriety selectively adaptively according to the length of the period of the level of the reproducing beams side. When the reproducing beam period is a prescribed value NT or longer, the sample-and-hold is decided as 'yes'. A delay circuit 38 delays a recording information pulse by a prescribed time. The delay time is (N-1)T when the period required for the decision of the sample-and-hold is NT. A laser driver 18 receives a delayed pulse 44 from the circuit 38, and drives a laser oscillator 12. When the reproducing beam period continues the NT or longer, the sample-and-hold is executed by sample-hold circuits 20a, 20b, and the outputs are sent to a differential amplifier 22, and the difference becomes a tracking error signal.

Abstract: PURPOSE:To perform high-quality color printing which is free from color deviation, etc., by transferring colors superposedly at the same position, by controlling the operation of state changing devices so that the devices can operate in accordance with the detecting output of an optical position detector. CONSTITUTION:In a laser beam optical system 3a, a mirror 13a is supported by a mirror supporting body through piezoelectric elements 30a and 31a which work as state changing devices. The lengths of the elements 30a and 31a are electrically elongated/contracted and the elements are provided with a gap between them in the auxiliary scanning direction in the form of a pair.
