Title: Manufacture of ceramic substrate
Inventor: KUDO KOICHI
IPC: H05K1/03
Filed: 1995-08-17
Abstract: PROBLEM TO BE SOLVED: To prevent the shrinkage of a ceramic substrate when burning it and secure the goodness of the solder wetting and electrical connection of its wiring, by making its shrinkage preventing green sheet out of at least selected one kind of magnesium, calcium and strontium carbonates or out of the mixture of the carbonate with at least selected one kind of oxide, nitride and carbide. SOLUTION: As a material powder, the calcium carbonate powder of 1.1μm in average grain size 100 pts.wt. is used to create a shrinkage preventing green sheet of about 200μm in thickness. Then, five sheets of glass-ceramic green sheets with completely formed wirings are superimposed on each other, and further, on both the sides of the laminate, the shrinkage preventing green sheets are superimposed respectively to mold the laminate pressingly under the conditions of 150kg/cm<2> and 85 deg.C. This molded material is put on an alumina plate of 0.05% in flatness and 70% in porosity to heat it at 520 deg.C during three hours and remove contained organic matters from it. Subsequently, the processed material is burned by heating it at 900 deg.C during one hour. The burning shrinkage percentage of the substrate obtained in this way is 0.3% in its planar direction.  Also, the examined percentage of the area of the board whereon solders are stuck successfully is about 100%.

Title: Magnetic field-controlled high stable light source
Inventor: NAKAGAWA SHIGERU
IPC: H01S3/131
Filed: 1995-08-17
Abstract: PROBLEM TO BE SOLVED: To obtain amplitude-stabilized output light from a magnetic field-controlled high stabilized light source with less noise by controlling a magnetic field generated from a magnetic field generator so that the detection signal corresponding to the output light can become a prescribed value. SOLUTION: The output laser beam 6 of a laser 1 travels as laser beams 8, 10, and 12 by branching off an output laser beam 7 and wavelength detecting laser beams 9 and 11 whenever the laser beam 6 passes through semitransparent mirrors 20, 22, and 24. A photodetector 26 detects the intensity of the laser beam and, when a switch 52 is closed, outputs the intensity to a power control source control circuit 5 as a light intensity output. The circuit 50 integrates and amplifies the differences between the light intensity output of the photodetector 26 and modulated signals inputted to a modulated signals inputting terminal 50 and outputs the amplified result to the control terminal M of a power source 3 as a control input. The power source 3 supplies an element current to the element 1 in accordance with the control input.  When an error signal represents the excessively strong intensity of the laser light, the polarity of the error signals is selected to as to reduce the current of the element 1. Therefore, the intensity of the laser light 7 can be adjusted in accordance with the modulated input.

Title: Exhaust discharging device for internal combustion engine
Inventor: YAMAGUCHI SHOZO
IPC: F02B27/06
Filed: 1992-08-10
Abstract: PURPOSE:To carry out favorable suction operation by forming a throttle part at a part of an exhaust flow passage, opening a hole for sucking air, etc., in the vicinity of the throttle part, and increasing the flow speed by reducing the effective sectional area in the throttle part when the exhaust quantity is small. CONSTITUTION:The exhaust gas of an internal combustion engine flows out through a passage 20. A throttle part 21 is formed in the passage 20, and the exhaust is allowed to flow at a high speed. A plurality of holes 22 for sucking the exhaust which passes through a flow passage 17 are opened at the part where the inside diameter increases at the terminal. A guide pipe 28 is installed at the opened port part 26 of the flow passage 20, and outside the guide pipe 28, a flow speed adjusting device 25 is formed by fitting a control member 30 having a cylindrical part 31 and the small and large diameter parts 32 and 33 for the control member 30 to freely advance and retreat. When the flow rate is large, the control member 30 reaches the outer edge, being pressed by the exhaust, while if the exhaust is reduced, the large diameter part 33 intrudes into the throttle part 21, being pushed by a spring 38, and the sectional area of the exhaust flow passage is reduced, and the flow speed is increased, and the pressure is lowered, and the flow rate sucked into the hole 22 from the flow passage 17 is increased. Accordingly, even in the low speed operation, the excellent suction operation is enabled.

IPC: G03B27/62
Filed: 1984-11-05
Abstract: PURPOSE:To obtain a copy of invariable good quality by allowing a paper feeding means to operate continuously for longer than the time required by an original to reach an exposure part. CONSTITUTION:The time constant of a one-shot circuit Q10 is larger than the time when an original after transfer at a stopper part is sent and smaller than the time when an uncopied original sent out of a bucket part reaches the stopper part, and set to the timing of a check signal for jam detection. The original is set at an exposure position by a stopper and then a copying machine frame starts making an exposure scan. Further, a photosensitive drum is turned once so as to obtain a stable image after a copy command signal START is inputted to the copying machine frame through a relay K2, and exposing operation is started. The copy start signal is sent to the copying machine frame to that Ta> Tb, where Ta is the time required for said turn of the drum and Tb is the time from the turn-on operation of the relay K2 to the setting of the original at the exposure position.

Title: Manufacture of information recording disk
Inventor: TODE YUKARI
IPC: G11B11/105
Filed: 1988-09-17
Abstract: PURPOSE:To manufacture the disk easily with preferable workability and to prevent oxidation and corrosion of the information recording layer by applying a resin solution on the whole surface of a transparent plastic substrate on which a recording layer is formed and forming a light-transmitting moisture- proof protective layer on the whole surface by drying or curing the binder solution. CONSTITUTION:The information recording layer 2 is formed on the light- transmitting plastic substrate 1 by vapor deposition, for example. Then Fluorocoat EC-104 is applied wholly on the substrate with the formed recording layer 2 by immersing, and then dried at room temp. to form the light- transmitting moisture-proof protective film 7. As Fluorocoat EC-104 used to form the light-transmitting moisture-proof film 7 is quick-drying, taking several ten seconds to become tack free and has low viscosity and nonsticking property, it gives easily a homogeneous thin film. Thus, the manufacture processes can be decreased and simplified. The protective film prevents permeation of water or the like and oxidation and corrosion of the information recording layer. The obtained recording disk shows no warpage and can be used stably for recording, reproducing and erasing for a long period.

Filed: 1982-12-28
Abstract: PURPOSE:To obtain a stable synchronizing signal even if a pulse shifts in phase by detecting the phase shift of the pulse signal and holding the input voltage to a voltage-controlled oscillator according to the detection output. CONSTITUTION:The level of an RF signal which is obtained by an optical pickup and supplied to an input terminal 36 is compared with a reference voltage by a comparing circuit 38 to generate an EFM signal.

Then, a phase state detecting circuit 40 detects a phase difference signal component based upon the regular phase shift of the EFM signal among phase difference signal components is detected by a phase state detector 40 to turn off an electronic switch 41. When the switch 41 is turned off, the output voltage of a loop filter circuit 18 is held at a value which is right before the switch 41 is turned off, and a VCO15 outputs an oscillation frequency based upon the held voltage to prevent a synchronizing clock signal from becoming unstable. Thus, the invariably stable synchronizing signal is obtained.

Abstract: PURPOSE:To avoid the effect of high frequency noise onto a degaussing coil by connecting the degaussing coil to an AC power supply via a switch and using the switch so as to interrupt the degaussing coil from a switching power supply device. CONSTITUTION:With a power switch 10 closed, an AC power supply 2 is fed to a switching power supply device 12 through feeding terminals 4, 6 and power is energized to a degaussing coil 14 through relay contacts 221, 222 and a posi tive characteristic thermister 16.
