Title: Power unit
Inventor: ASAKAWA NAOTOSHI
IPC: G05F1/56
Filed: 1989-06-16
Abstract: PURPOSE:To stabilize the characteristic of a switching power circuit and to improve the response speed by securing a high band for an error amplifying circuit with a negative feedback technique, then reducing the phase delay of the amplifier circuit. CONSTITUTION:A resistance element 9 is put into the input of an error amplifying circuit 7. The input voltage V2 is applied to an error amplifier 73 via the resistance elements 9 and 74, and the output current of the amplifier 73 flows to a light emitting element 72 and a resistance element 9. The end voltage of the element 9 is applied again to the amplifier 73 via the element 74, therefore, the amplifier 73 serves as a current feedback circuit which feeds back negatively the output current component. As a result, the value of the current I1 flowing to the element 72 is accurately proportional to the voltage V2. Thus a high band is secured for the circuit 7 with a negative feedback technique and the phase delay of the circuit 7 is reduced. Then the characteristic of a switching power circuit is stabilized and the response speed is improved.

Title: Band-pass filter circuit
Inventor: AKITA SHINICHI
IPC: G01R23/165
Filed: 1995-05-29
Abstract: PURPOSE: To limit the amplitude of ringing voltage to a low level by providing means for generating a control signal which increasing the inner resistance of a switch gradually before turning the switch off. CONSTITUTION: When a clock ϕr inputted to an input terminal 11 has 'H' level, a transistor 13 is turned on and an output terminal 14 goes 'H'. When the clock ϕr goes 'L', the transistor 13 is turned off and a capacitor C1 is discharged to the input terminal 11 side through a resistor R1 at a time constant of T=C1.R1. Consequently, a clock ϕa appearing on the output terminal 14 side has a voltage waveform rising gentler than the falling of the clock ϕr. When the clock ϕa having such waveform is fed to a refresh switch, the inner resistance increases gradually as the switch is turned on/off and eventually reaches the maximum value. Consequently, the switch can be turned off gently.

Title: Joint structure of piping for high temperature liquid
Inventor: ENOMOTO KUNIO
IPC: C08J5/04
Filed: 1977-12-21
Abstract: PURPOSE: To prevent stress corrosion breakage generating a compression stress at the internal wall of the pipe joint part by producing a temperature difference between the external wall and the internal wall of the pipe joint part.  
     CONSTITUTION: The distance (L) of the external surface of pipes 2 including the pipe joint part 1 is not covered with heat insulating material 3, but covered with a coiled cooling tube 4 through which coolant flows. The cooling tube 4 connected with a coolant supply tube 5 having an adjusting valve 6 and a coolant return tube 7 having a stop valve 8. The cooling tube 4 cools the external wall of the pipes 2 including the pipe joint part 1 by the coolant flowing through the coil. Temperature difference is produced between the internal wall and the external wall of the pipes 2 and the joint part 1 as the external wall is cooled by the cooling tube 4 and the external wall is heated by the high temperature liquid flowing through the piping as high a temperature as the temperature of the liquid, thus constraining free expansion of the internal wall of the joint part 1 by the external wall of the same. Consequently, compression stress and tensile stress of the same magnitude are produced in the internal wall and the external wall of the joint part 1, respectively,  so that the stress in the internal wall of the joint part 1 is reduced to prevent breakage.

Title: Arrangement type infrared detector
Inventor: AJISAWA AKIRA
IPC: H01L31/10
Filed: 1992-06-12
Abstract: PURPOSE:To obtain an element having high quantum efficiency and a low dark current and high sensitivity in a loop hole structure which can readily be integrated highly. CONSTITUTION:This embodiment has a structure that a forbidden band width of HgCdTe caps R/4, 6 in the vicinity of the front and reverse surfaces of a HgCdTe crystal, which is adhered onto a silicon chip 1 having a signal processing part 2 and in which a photodiode 8 is formed, is larger as compared with the forbidden band width of HgCdTe infrared ray absorption R/5 inside the crystal. As carriers (electrons) generated in the infrared ray absorption R/5 becomes hard to diffuse to the vicinity of the front and reverse surfaces containing a great amount of crystal defects by a difference in a band gap, the carriers due to a surface re-coupling do not disappear to obtain high quantum effects. Also, a surface leakage current is suppressed at a PN junction to contrive a low dark current of a diode. Thus, it is possible to obtain an arrangement type infrared ray detector having sufficiently high sensitivity in a loop hole structure.
