Title: Excavation unloading device
Inventor: HYODO KAZUYA
IPC: E21B11/00
Filed: 1994-03-01
Abstract: PURPOSE:To make it possible to carry out excavating and unloading work at a high speed without generating a large impact vibration. CONSTITUTION:This device comprises a drive shaft 34, which is covered with a cutter case 33 and which is pushed in under-ground while it is being driven rotatively. An excavation blade 35 is mounted to the tip of the drive shaft 34 while a rotor 37 is mounted to the drive shaft 34 in the rear of the excavation blade 35, thereby excavating the earth with the excavation blade 35 by the rotary motion of the drive shaft 34. At the same time, an earth and sand chamber 41 is installed outside the cutter case 33 so as to place the excavated earth and sand carried with the rotor. This device also comprises an earth removal pump 49 which brings out the excavated earth and sand kept in the earth and sand chamber 41 to the ground. The ground is excavated with the excavation blade 35 by the rotary motion of the drive shaft 34 while the excavate earth and sand is carried in the cutter case 33 with the drive shaft 37 and discharged into the earth and sand chamber 41. The excavated earth and sand, earth ana sand, which is discharged into the earth and sand chamber 41, is brought out to the ground by means of the earth removal pump 49. This construction makes it possible to excavate the ground and unload the excavated earth and sand continuously at a high speed without generation a large impact vibration.

IPC: H01L23/04
Filed: 1992-02-19
Abstract: PURPOSE:To prevent the generation of an accident that even if a sealing brazing metal on the sides of earth terminals flows out along the side surfaces of a semiconductor container, the brazing metal reaches earth gold wires to come into contact with them and the gold wires are fuse-cut by a method wherein the container is provided with rodlike protrusion bodies, which are arranged on a substrate in such a way that recessed parts are formed in the substrate in parallel to the sidewalls, which are located on the sides of the earth terminals, of the container and have an arrow-type section. CONSTITUTION:Ceramic rodlike bodies 2A and 2B having an arrow-type section are arranged on a substrate 1 in such a way that recessed parts 16 are formed in the substrate in parallel to the sidewalls, which are respectively provided with earth terminals 4A and 4B, of a semiconductor container. The container is provided with the ceramic rodlike bodies 2A and 2B having the arrow-type section and earth gold wire connection parts 3A and 3B for connection of earth gold wires 15 formed through metallization on the bodies 2A and 2B. Even if a sealing brazing metal 13 on the sides of the terminals 4A and 4B flows out along the side surfaces of the container, the generation of an accident that the metal 13 reaches the gold wires to come into contact with them and the gold wires 15 are fuse-cut can be prevented.

Title: Heat exchanger and its manufacture
Inventor: TANAKA HIROSHI
IPC: B23K1/00
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To largely reduce a cost and to eliminate inconvenience of manufacture by forming a core and a tank separately, disposing a brazing material at a connecting part of the both, and melting the material by high frequency heating. SOLUTION: A tube 5, fin 6, side plate 7, and bracket 8 are integrally brazed in a furnace, and a core 4 is previously formed. And, tanks 2, 3 are manufactured, and a bracket 11 is integrally provided at the one tank 2. The core 4 and the tanks 2, 3 manufactured separately in this manner are connected by arranging a connecting part 12 between a surface 4a of the core 4 of the tank 2 side and a surface 2a of the tank 2 of the tank 3 side and a connecting part 13 between a surface 4b of the core 4 of the tank 3 side and a surface 3a of the tank 3 at the core 4 side, connecting them, high frequency heating them, melting a brazing material, and connecting them. Thus, the entire heat exchanger is not necessarily integrally brazed to reduce a manufacturing cost.

Title: Recording paper feed system
Inventor: KURATA MASAMI
IPC: B41J2/325
Filed: 1981-03-06
Abstract: PURPOSE:To feed cut recording papers while keeping their intervals minimum at a continuous recording time, by feeding the next recording paper in a speed approximately equal to the subscanning speed of a recording paper in a recording part. CONSTITUTION:The trailing edge of a preceding cut recording paper 3 where information is recorded through a feed roller 4, resist rollers 8, a back roller 11 which changes the circumferential speed in inverse proportion to the quantity of picture information to transfer and record information thermally from an ink donor sheet 1 in the variable speed scanning system, etc. is detected by paper sensors 7. Before recording for this preceding recording paper 3 is completed, the roller 4 is turned in a speed approximately equal to the variable speed of the roller 11 to start feeding a cut the recording paper 3. Next, the recording paper 3 is fed by rollers 8 turned in a circumferential speed approximately equal to that of the roller 11 while keeping the interval between the recording paper 3 and the preceding recording paper 3 minimum, and thus, an efficient continuous recording equivalent to the use of a roll paper is possible.

Title: Scanning optical device
Inventor: UZUKI KAZUO
IPC: G02B26/12
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To cause no problem of safety even when a laser light shield means is in closing operation and project light which is large enough in quantity for use for measurements, etc. SOLUTION: When a laser shutter 28 is closed, a press part 30 is always pressurized to the left by a return spring 33 and stops abutting against the projection part of an optical box 20, and consequently a light shield part 32 cuts off luminous flux emitted by a semiconductor laser light source 21 so that several % of it leaks. Further, when the laser shutter 28 is opened, the press part 30 is pressed by a depression member 29 to move the laser shutter 28 to the right and the light shield part 32 on the optical path moves to a position where the optical path of the laser light is not cut off, so that the light is passed by 100%.

Title: Mobile radio communication system and selective radio call receiver
Inventor: FUJISAWA ICHIRO
IPC: H04Q7/28
Filed: 1994-03-01
Abstract: PURPOSE:To easily change a service area by performing a switching operation on the side of a radio calling device and switching the service area corresponding to the schedule of action on that day. CONSTITUTION:A control part 10 of a radio calling device 3 generates reservation information from received move information and transmits this reserving signal from a transmitter 4 to a selective radio call receiver 7 as a radio signal. This selective radio call receiver 7 switches and sets the service area so that a receiving state can be correspondent to the moving destination service area at the designated switching time contained in the received reserving signal. When the user of the selective radio call receiver 7 can not confirm the reception of the reserving signal to this selective radio call receiver 7, a retransmission request is enabled to transmit the already transmitted reserving signal to a radio calling device 3 again. Thus, the switching operation is executed on the side of the radio calling device 3 and the service area can be easily switched corresponding to the schedule of action on that day.

Title: Evaporative gas discharge inhibit device for fuel tank
Inventor: SASAKI MICHIAKI
IPC: B60K15/077
Filed: 1985-02-20
Abstract: PURPOSE:To reduce the size of a canister and prevent fuel to flow outside by connecting the canister to a bent hose and providing the midway of the bent hose with a shut-of valve which is opened only when a fuel filler-lid is opened. CONSTITUTION:A bent hose 7 is connected at one end to the top of a fuel tank 1 and at the other end to a canister 8. An electromagnetically operated shut-off valve 9 is incorporated in the midway of the bent hose 7. The shut-off valve 9 comprises a valve disk 9a normally closed by the pressure in the fuel tank 1 and valve casing 9b in which the valve disk 9a is built. The valve disk 9a is opened by a coil 9c energized in response to a signal from a lid switch 10 for detecting that a fuel filler-lid 5 is opened. Thus, since the shut-off valve 9 is normally closed except in fuel supply and the canister 8 will suffice if it absorbs only a gas evaporated from fuel flowing in its supply, the volume of the canister 8 may be relatively small.
