Abstract: PURPOSE:To decrease the dispersion of a diffused layer and to make it possible to use the layer repeatedly for a long time, by forming metal oxide material whose surface layer is porous in a wafer shape, impregnating conductive type determining imourities in the metal oxide, and obtaining the impurity source diffused in gaseous phase. CONSTITUTION:For example, porous ceramics 3 whose main component is alumina are stuck to both surfaces of non-porous ceramic substrate 2, and sintered. The size of the disk shaped ceramics is slightly larger than the wafer 4 which is to be diffused. Said substrate 1 is dipped in organic solution of e.g. B2O3, and the B2O3 is packed into air holes. Thereafter, the substrate is dried and the diffusing source of e.g. B is obtained. In the similar way, the substrate is dipped in the organic solution or suspension of phosphorous pentaoxide, antimony oxide, As2O3, and the like, and the impurity sources of P, Sb, and As are obtained. The impurity imregnated substrates 1 prepared in this way are placed on a boat 5 so as to face the diffused surface of the wafers 4. The boat is inserted into a furnace and the gaseous phase diffusion is performed. The dispersion in the diffused layer, in the wafer, within a lot, and between the lots can be decreased, and the reproducibility and the uniformity can be improved.

Abstract: PURPOSE:To simplify the timing adjustment of devices in an automatic winder and as well to facilitate the maintenance thereof, by detecting whether a unit is in the operating condition or not upon control of the winder so that a microcomputer controls a doffing device, a bypass device, etc. CONSTITUTION:In an automatic winder 5, after the number of units and the number of spooled threads which are necessary for winding up one cheese are set in the central process unit 8 of a microcomputer, the computer computes a unit number when each unit passes through a unit confirming device S1. Then, an operation detecting device S2 determines whether the associated unit is in the operating condition or not, and if it is in the nonoperating condition, a bypass device 3 is operated. If it is in the operating condition, a remaining thread detecting device S3 determines whether the thread remains on a bobbin or not. If any remaining thread is there, the bypass device is operated, and an intermediate thread breakage S4 detects the presence of an intermediate thread breakage. If any intermediate thread breakage is detected, a relay device 7 is operated to carry out the relay. If no thread is on the bobbin, an automatic doffing machine 2 is operated.

IPC: F24C7/04
Filed: 1982-02-17
Abstract: PURPOSE:To make both uniform heating throughout a room and local heating possible by a method wherein blasting action due to the rotation of an impeller provided in a duct, heating action of a heater provided in front of a reflecting plate and heating action of a heater, which interlocks with a damper to open and close the duct, are selectively combined with one another. CONSTITUTION:When only the junction between contacts (a) and (b) of a switch 16 is closed, only a motor 10 is energized and consequently the impeller 11 is rotated in order to produce air stream forwarding from a suction port 2 to an discharge port 3 in the duct 8 or to perform blasting opertion. On the other hand, when only the junction between contacts (c) and (d) of the switch 16 is closed, a plurality of lamp heaters 7 are energized to produce the heat, which is reflected with the reflecting plate 5 in order to be radiated forward. Furthermore, when said junctions are simultaneously closed, the blowing-off of hot air is accomplished. In this case, when the damper 13 is set at its open state in the duct 8, a switch 18 is closed in order to allow a coil heater to generate heat so as to uniformly heat throughout the room, while when the damper 13 is set to block the duct 8, the local heating is accomplished.

Filed: 1983-02-15
Abstract: PURPOSE:To improve the reproduction S/N ratio of an audio FM signal by providing a band limiting circuit for the upper-side-band wave of a luminance FM signal to be recorded. CONSTITUTION:The band limiting circuit 35 is provided for the upper-side-band wave of the luminance FM signal to be recorded, and when it is recorded while mixed with the audio FM signal, no energy is present in the upper-side-band wave even if a tape head system restores the low-side-band wave.

Title: Nipping-side contact of disconnector
Inventor: MATSUKAWA SATOSHI
IPC: H01H31/28
Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To suppress the displacement produced between a nipping-side contact and a nipped-side contact to perform a stable contact by pressing a finger contact by the nipped-side contact in times of abnormality, and bringing the head part of a rivet to a support to support the finger contact. SOLUTION: When a blade 7a is moved horizontally due to an earthquake, and a force for pressing the tip of a finger contact 29 acts to press the finger contact 29 beyond the angle where a rivet 28 makes contact with a support 11, the fulcrum of the finger contact 29 is transferred from a projection part 17 to the head part of the rivet 28. Thus, the ratio of the distance from a fulcrum to power point to the distance from fulcrum to working point is larger than when the fulcrum is in the projection 17, and the force resisting against the pressing force of a spring 13 is increased. Thus, the horizontal movement of the finger contact 29 is suppressed to prevent the reduction in the contact pressure necessary for the current-carrying between a nipped-side contact 6b and the finger contact 29, and the allowable performance with respect to short- time current can be higher than at normal.

Title: System for automatic cleaning of solar battery panel
Inventor: ISHII HIDEMASA
IPC: H01L31/042
Filed: 1983-02-16
Abstract: PURPOSE:To perform unmanned operation by automatically cleaning a photo receiving surface by a method wherein an automatic valve provided to a cleaning water pipe is opened under the condition that the strength of a detection signal from a photo receiving element is over a fixed value, and then cleaning water is sprayed to the photo receiving surface from a nozzle provided to the pipe. CONSTITUTION:A convergent light (parallel light) corresponding to an impressed voltage is generated from a photo emitting element 6; when the photo receiving surface 2 is stained by foreign matters X such as dust, said light reflects there and then advances straight by passing again through the titled panel. Then, it becomes incident to the photo receiving element 7 and then a photocurrent detection signal generates by said element 7. Thereby, said signal is detected by a level detector 8. When its strength is over the fixed value, this device operates and emits an output. The automatic valve 11 is opened by this output, and the cleaning water spouts out from the nozzles 12 provided to the cleaning water pipe 10, thus cleaning the photo receiving surfaces 2 of the solar battery panel. When the foreign matters such as depositing dust are removed, the convergent light is not reflected on the photo receiving surface 2 but passes therethrough as it is. Then, the output from the level detector 8 is stopped being emitted, resulting in the state of full closure of the automatic valve 11, and therefore the spouting of the cleaning water is stopped.
