Title: Build-up welding method and build-up welding apparatus
Inventor: TOKUNAGA KOJI
IPC: B23K20/12
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To execute the build-up welding on the surface of a base material while restraining the deformation and the strength decline due to heat by shifting a friction member driven in correlation to a thin sheet-like welding material covering a recessed part arranged on the surface of the base material having the recessed part while the friction member is pushed to the welding material. SOLUTION: The thin sheet-like welding material 4 is set on the surface of the base material 3 so as to cover crack 3a. The welding material 4 is made of an aluminum alloy of the same material as the base material 3. In this state, the friction bar 1 is rotationally driven at a prescribed number of the rotations with a driving means 2, and also shifted while being pushed to the welding material 4. At this time, the friction heat is generated mainly by the tip surface 1a of the friction bar 1 contacting with the welding material 4. The welding material 4 and the base material 3 are heated with this friction to temperature lower than the melting point of the aluminum alloy forming these materials but heated to sufficient temperature to plastically fluidize.  Further, the welding material 4 is plastically fluidized in the peripheral direction according to the rotation of the friction bar 1 and mixed and joined with the base material 3 to effect the build-up welding on the surface of the base material 3.

Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To obtain crystal growth efficiently and simply by using an organic phosphoric compound as a V feed gas, supplying the gas with a specific pressure, and growing a self-stop-type single-molecular layer. SOLUTION: TEI(triethylindium) and TBP(t-butylphosphine) gases are supplied to an InP substrate 102 from feed gas containers TEI 106c and TBP 106e through each gas supply line. A crystal is grown for each molecular layer at a time while repeating alternately supply where the TEI gas is supplied, then the TEI gas is eliminated (purged) by vacuum evacuation using a turbo pump 109, and then the TBP gas is supplied, and then the TBP gas is purged for the alternate supply of the feed gas. In this case, the pressure in a chamber 101 to be purged is set to 1 Pa or less. Further, a V gas is liquefied by a liquid nitrogen trap 107 to reduce partial pressure.

Filed: 1994-09-19
Abstract: PURPOSE: To provide a safe and convenient clip by using it after a pin is housed when it is not used as a pushpin, and projecting the pin to the reverse side of a board when it is used as the pushpin. CONSTITUTION: When a lug piece 31 of a lug member 3 is push-moved to the lug piece 12 side of a clip body 1 as shown by a dashed line, an action plate 24 and a receiving plate 26 are pushed, and a part between a sandwiching- installing piece 21 of a sandwiching-installing member 2 and the tip of a sandwiching-installing piece 13 of the clip body 1 is widened against elastic repulsive force of a torsion spring 5.

Title: Inter-music falling position adjuster of automatic music selection record player
Inventor: YAMADA JIROU
IPC: G11B17/22
Filed: 1983-12-29
Abstract: PURPOSE:To adjust the falling position between pieces of music of an arm without receiving the influence by the structural load and temperature characteristics by converting the adjusting value of the falling position between pieces of music to the digital value of the distance and by storing it in a control circuit. CONSTITUTION:Before a tone arm moves to the moving operation, the pulse such as a signal 36 is added to a timer circuit 29 from an output OUT3 of a microcomputer 28, and at the same time, the pulse such as a signal 35 is added to an AND circuit 30 from an output OUT2. Then, the electric potential of the (c) point lowers slowly with a time constant C2R2 as shown in a signal 37, the electric potential of a comparator 42 changes from ''H'' to ''L'' when the electric potential of the (c) point becomes lower than that which is adjusted by a semifixed volume 34, that is, the (d) point, and as a result, the pulse signal 35 which is outputted from the microcomputer 28 during a timer time T2 is inputted to an input IN4 of the microcomputer 28. In other words, the pulse such as shown in a signal 39 is inputted in the microcomputer 28. Therefore, the number of pulses which are inputted to the microcomputer 28 changes by changing the semifixed volume 34.

Title: Analog-digital converter and compensation of digital signal generated by analog-digital converter
Inventor: DABURIYUU ESU HENRION
IPC: H03M1/10
Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To reduce the distortion of digital signals generated from an analog- digital converter by digitally compensating the digital signals. SOLUTION: The compensation factor which compensates the nonlinearity of a digital-analog converter 20 is decided by operating the converter 20 in a calibration mode. During the calibration mode, a multiplexer 21 selects a digital oscillator 26 and gives a digital value from the oscillator 26 to digital compensation 23. Therefore, the converter 20 generates an analog output 25 containing at least one frequency component in response to the oscillator 26. The nonlinearity of the converter 20 generates the other frequency component than the component generated from the oscillator 26 and appears in the output 25 of the oscillator 20. The nonlinearity is removed by adjusting the compensation factor and only the frequency component generated from the oscillator 26 appears in the output 25. A compensation factor calculating device 28 calculates the value of at least one compensation factor of a storage device 24 so as to remove a distortion component when a detector 27 detects the distortion component. This process is repeated until the distortion component becomes lower than a prescribed level.

Title: Stabilized electrostatic charging method
Inventor: MIYAGAWA NOBUHIRO
IPC: G03G13/02
Filed: 1983-12-28
Abstract: PURPOSE:To prevent memory after-image development without decreasing the amount of charging by providing a detrapping process wherein a conductive flexible member applied with a bias voltage is brought into contact between a cleaning process and a charging process. CONSTITUTION:Residual charges on a photosensitive drum 11 after toner transfer are removed by the front-surface exposure of a discharging lamp 21 and residual toner is removed by a cleaning mechanism 22, so that the photosensitive drum 11 has optical fatigue of order which can not be ignored. When detrapping is carried out previously by applying a bias voltage before the charging, surface charges are not neutralized in the earliest charging, so the optical fatigue is prevented completely. For the purpose, the bias voltage is applied from a conductive rubber roller 31 connected to one electrode of a power source 30 which is grounded at the other electrode. The level of the bias voltage depends up the kinds of the light source in use and an amorphous silicone photosensitive body and is generally 90-400V.

Abstract: PURPOSE:To efficiently separate, send out and stack sheets including a bent sheet and a torn sheet, by providing a send-out means, which is moved away from the surface of the stacked sheets at the time of their stacking and brought into contact with the sheets at the time of their separation and takeout. CONSTITUTION:When paper money B is to be separated and sent out after the reception and stacking thereof, a pick-up roller 34, a roller, a guide roller 39 and a stopper 47 are brought into contact with the top of the paper money B. A feed roller 20 is rotated, and the pick-up roller 34 is intermittently rotated synchronously with the feed roller through the action of a gear 28 and a cam 31 so that the uppermost paper money B pushed on the pick-up roller is sent into a separating section made of the feed roller 20 and a gate roller 25. At that time, the ascending deformation of the non-separated portion of the paper money B is restrained by the guide roller 39 so that the posture of the paper money is kept constant. This results in stably sending out the paper money B toward the separating section.
