Title: Solid state image pickup device
Inventor: MIYATA YUTAKA
IPC: H04N5/335
Filed: 1980-05-20
Abstract: PURPOSE:To prevent the expansion of a blooming or scratch by picking up the variation in the current between a source and a drain due to the variation in the gate potential caused by the charge generated by a light as light information. CONSTITUTION:A circuit element having a charge transfer function is formed of MOS field effect transistors 31-34. A photoconductor 19 and the second electrode metal (transparent electrode) 20 on the photoconductor are formed through the first electrode metal 18 at every picture element on a semiconductor substrate 10. Electrons and holes generated by the light in the photoconductor 19 move to the electrodes 20 and 18 to vary the potentials of the gates 13, 14, and light information is picked up as the variation in the current between the source 11 and the drain 12. Thus, even if there are strong incident light and scratches, the electrode 18 is maintained at transparent electrode potential, thereby eliminating the output of unnecessary charge and preventing the expansion of blooming or scratches.

Title: Arc starting method in multilayer welding
Inventor: MATSUI NOBUHIKO
IPC: B23K9/00
Filed: 1985-03-29
Abstract: PURPOSE:To increase the efficiency in arc generation and to realize unmanned automation surely and under high reliability by impressing the prescribed voltage with weaving a welding torch only in short time just before the welding start. CONSTITUTION:Only a weaving W is performed without moving torch 1 in welding line direction for short time only just before the welding start on the second layer and on in case of performing the multilayer arc welding of one layer one pass method with weaving W the welding torch 1.

Title: Coaxial type equalizer
Inventor: KAGEYAMA TAKAO
IPC: H03H7/01
Filed: 1986-03-25
Abstract: PURPOSE:To obtain a coaxial equalizer with a high Q characteristic by providing a means adjusting the position of a short-circuit end of a center conductor of a subs coaxial line and a means adjusting the interval between the center conductor of a main coaxial line and the tip of the center conductor at the open end side of the sub coaxial line. CONSTITUTION:The inductance L of the sub coaxial line is varied by using an adjusting screw 7 to change the position of a short-circuit device 5 of the sub coaxial line, and the capacitance C between the center conductor 2 and 3 is varied by using the adjusting screw 6 to vary the interval between the center conductor 2 of the main coaxial line and the center conductor 3 of the sub coaxial line. Thus, the sub coaxial line acts like a series resonance circuit whose frequency is variable and the resonance circuit is coupled with the main tuning circuit through the capacitance C. Thus, in decreasing the capacitance C by parting the interval between the center conductors 2 and 3, the energy flowing from the resonance circuit of the sub coaxial line to the main coaxial line is reduced and a very high Q characteristic is obtained.

Title: Crystal evaluating method
Inventor: TAKANO HIROZOU
IPC: G01N21/3563
Filed: 1978-06-05
Abstract: PURPOSE:To enable impurity concentration distributions such as of C, O in Si substrate to be evaluated accurately and rapidly by radiating infrared ray fluxes so as to intersect perpendicularly to the main plane of the Si substrate and yet letting the infrared rays scan in arbitrary directions. CONSTITUTION:Infrared rays generated in the light source 7 of a light source part 1 are divided to two components by concave mirrors 8, 9. The infrared rays condensed at the mirror 8 are further condensed in a concave mirror 10 and arrive at a movable mirror 14d through stationary mirrors 14a thru 14c, thus becoming the infrared ray flux on the measuring sample 5 side of a sample chamber 3. The infrared rays condensed at the mirror 9 are condensed in a concave mirror 12 and are made to the infrared ray flux 13 on the reference sample 6 side. As the mirrors 14a thru 14c are moved in a fixed direction, the sample 5 is scanned over the entire surface. The changes of only the abosorptivity of the infrared ray of the specific wavelengths in a spectroscope part 2 are plotted in a recorder 4, whereby the line analysis in the scanning direction of the infrared rays is made possible and the two-dimensional concentration distributions of the specific element are evaluated.

Title: Unit type air-conditioning machine
IPC: F24F13/22
Filed: 1992-03-26
Abstract: PURPOSE:To improve the lighting when an air-conditioning machine is installed in a window, the exclusion of the regulation of the thickness of a wall and the facilitation of installation works when the machine is installed through a wall and the improvement of safety of the air-conditioning machine. CONSTITUTION:The size of the height of the indoor side front surface of the title air-conditioning machine is designed so as to be 1/2 of the size of the width of the same machine or less. In order to achieve the sizes, a horizontal type compressor 12 is loaded on the unit type air-conditioning machine at first while an indoor fan 5 and an outdoor fan 11 are constituted of sirocco fans. On the other hand, a propeller fan can not be used in the outdoor side of the machine since the height is to be lowered and a slinger ring, integrated with the propeller fan so far, can not be used to contrive the perfect evaporation of condensed water and, therefore, the outdoor side fan motor 10 is equipped with double-shaft mechanism and the outdoor side sirocco fan 11 is attached to one end of the shaft while the slinger ring 13 is provided on the other tip end of the shaft.

Filed: 1983-04-18
Abstract: PURPOSE:To achieve large driving force with small and light structure, by transmitting the motion of movable section due to air pressure through a power multiplier mechanism based on the principle of lever. CONSTITUTION:Upon air feed to an air feed hole 32, the air pressure in a pressure chamber comprised of a casing 31, seat valve 34, piston 33 and O-ring 13 will increase to slide the piston 33 against the pressure of spring in axial direction by the distance between a disc 37 and an armature 35. Here the movement of armature 35 is 81 to push a push rod 1 through a movable chip 36 thus to move by 82. The movable chip 36 will function as a power multiplier employing the principle of lever. When multiplying the moving force of the piston 33 and converting the direction of force by means of the movable chip 36, the size and the weight can be reduced when compared with conventional driver for producing same driving force.

Abstract: PURPOSE:To make fail-safe promotion attainable, by operating an elastic film deformation restricting device at the nonrestricting position while an on-off member at the closing position, respectively, excepting the specified value of actuator working pressure, in case of a car engine mount. CONSTITUTION:At a high frequency range of roll vibration in an engine 3, a controller 32 controls each of selector valves 26 and 31, opening an on-off valve 14. And, each hydraulic chamber 21b of actuators 21 is interconnected to a tank 41, and vibrations in a car body are absorbed by free deformation of each elastic film 7. On the other hand, at a low frequency range, pressure oil is fed to these hydraulic chambers 21b, checking the deformation of these elastic films 7, and vibration are reduced by fluid movement between fluid chambers 8 through conduits 10. And, when torque is high, the on-off valve 14 is closed. In this connection, since a plunger 17 of an elastic film deformation restricting device 18 is energized at a nonrestricting position of each elastic film 7 while the on-off valve 14 at the closing position, respectively, even if working hydraulic pressure becomes out of the specified value due to trouble or the like in a hydraulic pump 24, each of actuators 21 and 28 is kept in a nonoperational state, thus a fail-safe condition comes to fruition.
