Title: Converter with helical antenna
Inventor: YAMAMOTO HIROHIKO
IPC: H01Q11/08
Filed: 1987-07-24
Abstract: PURPOSE:To attain simplicity and miniaturization by providing a magnetic field coupling loop provided to a radio wave reflector so as to be penetrated through an insulator, providing a helical conductor to its one end, having the other end to be inserted in the inside of a waveguide and connected to a radio wave reflector so as to reduce number of components. CONSTITUTION:A microwave signal caught by a helical conductor 21 is propagated in the coaxial mode through a coaxial part comprising a radio wave reflector 18, a conductor means 19, an insulator 20 in the coaxial mode from the helical conductor 21 and led to a magnetic field coupling loop 22 and its current reaches a radio wave reflector 18 along the shape of the loop 22. As a result, an induced magnetic field H is generated to link the loop 22 in the waveguide 15. The major component E of the electric field is induced accordingly. Thus, the waveguide 15 is excited by the waveguide propagation mode corresponding to the said electromagnetic wave component, a signal is propagated in the inside of the waveguide and converted again into the coaxial mode by an antenna probe 16 inserted in parallel with the electric field direction of the waveguide 15 and led to the internal circuit of the converter 14. Thus, the simple constitution and small-sized/light weight configuration are attained.

Title: Automatic grinding attachment
Inventor: ENDO YOSHIFUSA
IPC: B24B31/10
Filed: 1985-08-23
Abstract: PURPOSE:To simplify a device in structure as well as to make a work in operation changeable, by making a support body so as to go down along a guide rail with rotation of a rotary body, to have the work embedded in abrasives inside a tank and, after being rotated and ground by a rotary desk, to make it go up again. CONSTITUTION:A barrel tank 1 and rotary desks 15, 22 and 24 are all rotated, and when each work W is set to a chuck 14 in order at an uppermost position of a support body 12, this support body 12 gets going down, whereby each taper surface of these desks 15 and 24 comes into contact with it in an intermediate point in the down stroke, thus rotation is given to the work W. When the support body 12 further goes down, a support frame 23 moves to the right whereby the descent is not prevented, and when the desk 15 is separated from the desk 24, the support frame 23 is energized by coil springs 28 and 28, so it goes back to its original position. In addition, the support body 12 continues to go down, and at the vicinity of a lowermost position, the work W is embedded in abrasices inside the barrel tank 1, whereby each taper surface of these desks 15 and 22 comes into contact with the work, thus rotation is given to the work W so that it is ground and, after burrs are removed, the support body goes up and the work W is set free. Thus, a device is simplified, and manufacturing cost is reducible.

Title: Suspension of vehicle
Inventor: WATANABE KENICHI
IPC: B60G7/02
Filed: 1987-07-24
Abstract: PURPOSE:To improve durability of a suspension equipped with a swing arm by making one of connection points between the swing arm and a vehicle body to be relatively rotatable and the other connection point to be displaceable in the fore-and-aft directions. CONSTITUTION:When a body side 7 is fixed for example and if a vertical input is given to a wheel 1, a swing arm 11 swings about a ball joint 33 as shown with broken lines I and II. When a fore-and-aft directional input is given from the wheel side, it is transmitted to rubber bushes 35, 37 via the ball joint 33 and a link 21. As a result, the rubber bushes 35, 37 cope with the input by elastically deforming in the fore-and-aft directions commensurate with the input as shown with broken lines III and IV. Since this mechanism shares the functions of swing movement and elastic deformation with respectively separate nodal points, both durability and ease of deformation characteristic setting are improved.

Title: Thermal head split driving apparatus
Inventor: KISHI TOSHIAKI
IPC: B41J2/355
Filed: 1994-07-14
Abstract: PURPOSE:To prevent the temp. rise of a thermal head by dividing the printing data of one line according to the max. number of drive dots capable of simultaneously driving heating elements and reducing the number of drive dots while increasing the number of times of division when the accumulation heat temp. of the head becomes high at a time when the thermal head is subjected to time sharing driving according to the number of times of division. CONSTITUTION:At each time when a count value counting the number of ON- dots of printing pattern data reaches the max. number of drive dots (capable of simultaneously driving the heating elements of a thermal head 7), the data up to the dot position thereof is set to one block data to divide the printing pattern data at every block to subject the thermal head 7 to split driving. At this time, a number-of-drive dot selection part 8 alters the number of drive dots corresponding to the measured temp. of a temp. sensor 6 measuring the heat accumulation temp. of the thermal head 7 to increase the division number of the printing pattern data. As a result, the temp. rise of the thermal head is prevented to enable high-grade printing free from printing irregularity.

Title: Electric heating device
Inventor: MORIWAKI TAKASHI
IPC: F24C7/04
Filed: 1989-07-18
Abstract: PURPOSE:To prevent a heating resistor from being cooled and to perform a correct temperature control by an air flowing from a heater side by a fan by a method wherein a thermostat is placed between the heater and the heating resistor. CONSTITUTION:When a state of 'hot temperature' is set, for example, by a volume of a controller, a fan is rotated by a motor and air flows in a radial direction. The air at this time passes from a central part of a heater 8 directly through a part of the heater 8, converted into a hot air, thereafter the hot air rides over a stepped part 4, flows into a controller 13 to increase a temperature of surrounding atmosphere near the controller device. The hot air flowing from the heater 8 to the controller 13 at this time is not struck against the heating resistor 36 directly, so that heat from the heating resistor 36 is not influenced by the hot air, but heats a thermostat. The thermostat 22 is heated by the hot air flowing from an end part of the heater 8 and the generated heat of the heating resistor 36 set by the volume. A bi-metal 23 is displaced toward the heating resistor 36, a movable contact point plate 26 is reversed and then contact points 25 and 27 are moved away to stop an electrical energization for the heater 8.

Title: Method for repairing crazing of casting mold for making ingot
Inventor: OZAWA MASATOSHI
IPC: B22D7/06
Filed: 1983-10-03
Abstract: PURPOSE:To prevent sticking of slag to the crazing on the inside surface of a casting mold for making ingot and deterioration of the quality of the steel ingot cast in the succeeding batch by the effect of the slag by coating and packing a repair meterial consisting principally of expandable graphite into the crazing. CONSTITUTION:The molten steel 16 in a ladle 14 is cast by bottom pouring into plural pieces of radially erected casting molds via a pouring pipe 20 and a runner 22. A crazing 28 arises on the outside surface of the molds 10 owing to thermal fatigue upon repetitive use. Molten slag intrudes into the crazing 28 and remains there. Such slag contacts the molten steel to be cast in the next casting and there is the possibility of changing the compsn. of the molten steel and making the steel ingot rejective. Expandable graphite 30 consisting of laminar carbon in which oxygen is trapped is coated and packed into the crazing 28 in this case. The graphite 30 expands to prohibit intrusion and sticking of the molten slag in the stage of the next casting and therefore the contamination of the steel ingot by the slag is obviated in the succeeding casting and the steel ingot having always the target quality is obtd.

Title: Bipolar transistor device and manufacture thereof
Inventor: HIRAI TAKEHIRO
IPC: H01L21/331
Filed: 1988-07-26
Abstract: PURPOSE:To decrease the variability of a direct current property without the formation of a natural oxide film by a method wherein an extremely thin film of Ti or Ti alloy, whose thickness is smaller than the mean free path of carriers reversely injected into an emitter from a base, is formed on the emitter, and a polycrystalline silicon, to be an emitter electrode, is formed thereon. CONSTITUTION:A side wall insulator 8 is formed on the part of a primary face 1, where an emitter electrode is to be formed, covering the side faces of a nitride film 5 and a polycrystalline silicon 7. Next, a thermal oxide film 9 is formed on the upside of the polycrystalline silicon 7, and then the nitride film 5 formed on the main face 1 is selectively removed using the side wall insulator 8 as a mask. Then, a thin film 10 of Ti or Ti compound and a polycrystalline silicon 11 are formed on the whole face, which is subjected to a heat treatment, and then B<+> ions are implanted 22 into the whole face to make boron diffuse for the formation of a P-type active base 13. In this process, the thickness of the compound thin film 10 is made smaller than the mean free path of carriers adversely injected into an emitter from a base. By these processes, the diffusion of impurity from polycrystalline silicon into single crystal is facilitated. Thereafter, As ions 23 are implanted to form an n<+>-type emitter 14.
