Title: Receiving antenna for vertical polarized wave and receiver having antenna
Inventor: TAKAGI KOTARO
IPC: H01Q1/38
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To make an antenna small-sized in the antenna which receives incoming radio waves of a frequency that is a microwave or higher due to a vertically polarized wave. SOLUTION: Antenna elements 21 and 22 are formed on an edge plane 11 of a printed wiring board 10 on which a receiving circuit is mounted. The board 10 is provided inside a receiver so that the plane 11 can be vertical. A signal received by the elements 21 and 22 is supplied to the receiving circuit. Thus, cost that is needed for constructing an antenna becomes almost unnecessary. Also, the occupied area for the antenna can be reduced, and also the receiver is not made large by providing an antenna. Furthermore, characteristic dispersion can be suppressed. Also the loss of a signal line from the antenna to the receiving circuit can be made small.

Title: Sintering method for cermet
Inventor: TOBIOKA MASAAKI
IPC: C22C1/05
Filed: 1985-06-07
Abstract: PURPOSE:To obtain a dense sintered compact of cermet by subjecting a cermet consisting of a hard phase of Ti-containing double carbonitride and a binding metallic phase of Ni and Co to temp. raise up to a temp. close to the liquid phase-forming temp. in an Ar and/or H2 air flow in a sintering furnace and then to pulsatory motion between prescribed pressures. CONSTITUTION:For example, a mixture of commercial Ti(CN), WC and TaC is treated at 1,650 deg.C in an air flow of prescribed N2 partial pressure and then powders of Ni, Co, Mo and C are blended with the above powder mixture by wet blending. Subsequently, the resulting powder mixture is dried and compacted and the green compact is dewaxed in the sintering furnace and subjected to temp. raise from 500 to 1,250 deg.C in 7.5hr, while an Ar gas is allowed to flow in the sintering furnace and the furnace pressure is subjected to pulsatory motion between the pressures of 10<-1> and 10<-4>Torr. From the above- mentioned 1,250 deg.C upward, an N2 gas is introduced into the furnace, where the above compact is subjected to temp. raise up to 1,425 deg.C, maintained for a required period and then cooled in gaseous CO2 so that the desired sintered compact of cermet can be obtained.

Title: Method of starting arc welding
Inventor: NUMATA ATSUSHI
IPC: B23K9/067
Filed: 1984-06-18
Abstract: PURPOSE:To start welding stably and prevent occurrence of weld defects by generating an arc for specified time by initial current capable of arc starting and after maintaining at current lower than initial current for a specified time, changing to high steady-state current. CONSTITUTION:When making arc welding using a consumable electrode, an arc is generated for 0.4-3.5 seconds under initial current I1 capable of arc starting. Then, current is changed to current I2 lower than initial current I1, and after continuing this for 2-10 seconds, changed to steady-state current I3 higher than current I2. Thus, welding is started stably, and at the same time, swelling of a bead at starting part of welding is eliminated, and occurrence of weld defects such as incomplete fusion etc. caused by swelling of bead is prevented.

Title: Radio communication equipment
Inventor: KITO EIJI
IPC: H04B1/48
Filed: 1989-05-17
Abstract: PURPOSE:To attain the effective use of frequency by controlling and adjusting the length of a carrier sense time after the transmission standby state while referencing the number of times of reception of the carrier sense and the number of times of transmission of the information. CONSTITUTION:Five kinds of carrier sense times as T, 2XT, 3XT, 4XT and 5XT, after the transmission standby state in a radio communication equipment are provided. In case of varying the carrier sense time depending on the count, a radio communication system having the many number of times of transmission, the less number of times of reception and small setting value of a transmission/ reception number counting circuit 12, has higher probability of generating a transmission request and many chances to be put into a reception standby state. Thus, the value set to the circuit 12 requires a short time such as T or 2XT in the probability. Thus, the standby time from the transmission standby state to the short of transmission is reduced and the desired frequency is effectively utilized.

Abstract: PURPOSE:To make it possible to feed gas evenly to each unit cell of a unit cell laminated body and to gas circulation grooves of each unit cell, by forming a gas stay room with a partition board having numerous orifices, on the gas intake side of a gas feeding manifold. CONSTITUTION:When an oxidizer gas 13 flows into a gas stay room 15, the gas flow speed is reduced and the static pressure in the gas stay room 15 is increased.

Title: Magnetic head
Inventor: MURATA YUICHIRO
IPC: G11B5/115
Filed: 1991-05-29
Abstract: PURPOSE:To obtain a head free from distortion of the reproduced waveform by inclining and widening the spacer, which isolates a recording and reproducing head and an erase head from each other, in the vicinity of a slope not to pick up an unnecessary signal. CONSTITUTION:The recording and reproducing head side of a spacer 5 which magnetically isolates a recording and reproducing head 3 and an erase head 1 from each other is inclined in the vicinity of a medium slope 7 and is widened. When the signal recorded by a recording and reproducing gap 4 is taken out at the time of reproducing information, the signal is picked up even by the spacer part, but this signal is reduced because the recording and reproducing head side of the spacer 5 is inclined and is widened. Therefore, the reproduced waveform is not distorted. When a thin film made of soft magnetic materials like sendust is formed on the spacer 5, the same effect is obtained.

Abstract: PURPOSE:To prevent a chip area from enlargement being required for the insertion of aligning patterns, company names, item names, checking patterns, and the like by a method wherein characters, figures, and symbols are constructed in the metal region of a metal-insulator-semiconductor condenser. CONSTITUTION:On a silicon substrate 3, an aluminum layer 1 is formed by vapor deposition after the formation of a silicon oxide film 2 by a prescribed thermal oxidation method. Etching follows whereby the aluminum layer 1 is removed of unnecessary portions, for the formation of a MOS condenser. Insertion into the etching mask for the aluminum layer 1 of characters, figures, symbols 4, 4' results in a MOS condenser fully functioning as such while accommodating necessary characters, figures, etc. The area the MOS condenser occupies is enlarged by the characters punched through, but the chip area can be made small enough because the MOS capacitor grows larger not by the size of the characters, etc. but only by the area occupied by the incorporated characters and figures.

IPC: B23K11/11
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To provide a robot having a final wrist shaft used in common as a servo tool driving shaft. SOLUTION: A command E1 or E2 for exciting coils of hollow clutches 15, 16 is alternatively outputted from a robot control device 30. At the output time of the command E1, the command E2 is off, and an arm 18 is attraction- fixed to a fixing part of the hollow clutch 15. When a servo motor M6 is rotated in this state, only an arm 20 is rotatory-driven through an output shaft 12, a speed reducer 13 and a speed reducer output shaft 14, and relative rotational displacement to the arm 18 is generated to attain opening/closing action associated with the approach or separation of both arm tips 19, 21. At the output time of the command E2, the command E1 is off, and the arm 18 is attraction-fixed to a fixing part of the hollow clutch 16. Accordingly, even if the servo motor M6 is rotated, the arm 18 and arm 20 are integrally driven so as not to generate approaching-separating action between the respective arm tips 19, 21. With the use of simple mechanism, the servo motor M6 can be switched and used to drive a servo van.
