Title: Extruding method by connected extruder
Inventor: SUZUKI YOUICHI
IPC: B29C48/38
Filed: 1983-07-30
Abstract: PURPOSE:To reduce the variation of the material pressure of a screw by making the depth of the groove of a screw at a section, to which a material is fed from a first extruder, shallower than other sections or using a screw a from which a screw flight is removed. CONSTITUTION:A screw flight at a section 9 shown by a broken line in a screw 8 for the second step extruder is removed or the depth of a screw groove at the section 9 is made shallower than other sections. Consequently, since the resistance of the flight in a supply section with the revolution of the screw which has been generated can be removed or reduced, the variation of the quantity of a material fed and resin pressure can be prevented, and conventional problems can be solved completely. That is, the material pressure of the second step screw hardly varies, and finished products such as coaxial cables having excellent electrical characteristics such as a voltage standing wave ratio (VSWR) can be manufactured.

Title: Sealant injection tool
Inventor: MAEDA TAMOTSU
IPC: B05C17/01
Filed: 1989-06-01
Abstract: PURPOSE:To improve the efficiency of an injection work by a method wherein an extrusion skirt having a check valve and a notch energized through the force of a spring is mounted to the nozzle pert of a cartridge to extrude a sealant with an internal pressure. CONSTITUTION:An extrusion skirt 8 having a check valve 6 with a protrusion part 7 and a notch part 9 is mounted to a nozzle part 4 of a cartridge 2 having a piston 3. The check valve 6 is energized in a normally-closed state through the force of spring 5. When the protrusion part 7 is pushed by the surface of a member to be processed to open the check valve 6, a sealant 1 in the cartridge 2 is extruded. This constitution effects uniform and high-efficient injection of the sealant 1 without forming an uneven surface on a surface.

Patent JP-H04364717-A (JP)
Title: Manufacture of semiconductor device
Inventor: SUZUKI MASAYASU
IPC: G03F7/36
Filed: 1991-06-12
Abstract: PURPOSE:To improve device yield in manufacture of a semiconductor device. CONSTITUTION:In manufacturing a semiconductor device, a photoresist film 4 on wiring 3 is removed by ashing with a gas containing a reductive gas, while reducing the oxide film produced on the wiring 3 by an oxygen plasma. Since the oxide film on the wiring is reduced, only the photoresist film is eventually removed by plasma ashing without oxidizing the wiring 3. Therefore, the photoresist film is almost completely removed.

Title: Optical pickup
Inventor: MAEDA IKUO
IPC: G11B7/125
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for development of special parts and to provide an optical pickup without requiring the addition of an optical element to be exclusively used for a light receiving element for a forward monitor. SOLUTION: A forward monitor system may be embodied simply by forming a slope 9 on one of the optical elements, for example, a prism 6, disposed between a semiconductor laser 1 originally possessed by the optical pickup and an objective lens 3 and reflecting part of a beam 2 emitted from the semiconductor laser 1 to the light receiving element 8 for a forward monitor, without requiring the addition of the optical element to be exclusively used for the light receiving element 8 for the forward monitor. At this time, the slope 9 exists within a beam irradiation range from the semiconductor laser 1 and outside a beam effective range 2a for the objective lens 3 and, therefore, the recording/reproducing operation by the intrinsic effective beam is not hindered at all.

Title: Electromagnetic induction heater
Inventor: ENDO TAKANORI
IPC: H01F1/26
Filed: 1993-05-19
Abstract: PURPOSE:To heighten the inductance of an electromagnetic induction coil, improve heating efficiency by an eddy current of a heating part, and eliminate the resistance and the crack of a magnetic material by arranging a resinous soft magnetic material in the vicinity of an electromagnetic induction part. CONSTITUTION:For example, when an electromagnetic rice cooker 10 is constituted of an outer iron pot 11 and an inner iron pot 12, an induction heating coil 13 is arranged on the bottom surface and the bottom part inner periphery of the outer iron pot 11 so as to surround this. Though this basic structure is formed in the same as usual, a magnetic material 20 in which a soft magnetic material is compounded is arranged in an electromagnetic induction part in which a coil 13 is arranged. Here, the magnetic material 20 may be arranged in a radial shape in the vicinity of the coil 13 or may be arranged on the whole periphery except a heating part. In this way, magnetic flux generated with the coil 13 as its center can be cut off, and leakage of the magnetic flux is eliminated. Since powder having high magnetic permeability is desirable as soft magnetic powder to be dispersed and blended in resin, permalloy alloy, Sendust alloy, iron or cobalt type nonquality alloy are used, and these coercive forces are set not more than (1.00e).

Filed: 1994-06-22
Abstract: PURPOSE:To detect the boundary location of a video area and a no-image part when video where the no-image part exists in the upper and lower parts of video is inputted as a video signal. CONSTITUTION:When the signal level of a video signal to be inputted is lower than a luminance level L, an amplitude direction decision part 117 decides that the signal is the one belonging to a no-image part. When the number of data where the signal is decided to be the one belonging to the non-image part is more than a set value C per horizontal scanning period, a horizontal direction decision part 118 decides the period as the horizontal scanning period belonging to the non-image part. A vertical direction decision part 119 decides where the boundary location of a video area and the non-image part is from the decision result by the horizontal direction decision part 118. A time direction decision part 120 integrates the boundary location of the video area and the non-image part obtained by the decision in the time direction and performs a final judgment.

Title: System for setting path between mobile unit and radio base station
Inventor: OKADA MASAAKI
IPC: H04J13/00
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To distribute a load of a radio base station onto which calls are concentrated, to enhance the speech quality and to effectively utilize a communication capacity of a radio base station with a few calls. SOLUTION: In this path setting system, a base station controller 1 periodically requests a traffic density of each radio base station and compares the received traffic density. When a difference between the traffic density is higher than a threshold value, the controller 1 discriminates that there is a deviation in the traffic density between neighboring base stations. In this case, the base station controller 1 calculates a difference of the received electric field strength between a radio base station 2 with large traffic density and a radio base station 3 with small traffic density, and confirms it that the difference is a threshold or over.  When the base station controller 1 recognizes the difference from the received electric field strength, the base station controller 1 receives a frame error rate of a radio transmission channel 14 and discriminates whether or not a path can be set via a radio repeater 7. When discriminating the relay path, the base station controller 1 sets a path to a mobile unit 6 in an area with large traffic density extended to the adjacent radio base station 3 with small traffic density by using the radio repeater 7.
