Title: Controlling device of engine drive generator for electric vehicle
Inventor: ARAI YOSHIHIDE
IPC: B60L50/15
Filed: 1993-04-08
Abstract: PURPOSE:To make it possible to form an environment of driving being fit for the feeling of a driver. CONSTITUTION:ECU 20 recognizes a vehicle speed from the number of revolutions of a motor 14. In accordance with this vehicle speed, a generator controller 28 changes a chopping frequency of a field current supplied to a field coil 24a. Thereby noise corresponding to the vehicle speed can be generated without producing an adverse effect on the efficiency of power generation and also the number of revolutions of an engine can be changed in accordance with the vehicle speed. On the occasion, the number of revolutions of the engine is changed in a high-efficiency area wherein the efficiency of the power generation of the engine does not change nearly at all. Therefore the noise can be changed in accordance with the vehicle speed without having any adverse effect on the power generation.

Abstract: PURPOSE:To prevent the ooze-out phenomenon of excessively viscous ink and keep a writing trace beautiful by a method wherein an oil repelling treatment layer is formed on the surface of a conical tip end section retaining writing element such as a ball or the like guiding the viscous ink out. CONSTITUTION:A multitude of worked and formed conical tip end units 3 are dipped into the polymerized material of metallized polytetrafluoroethylene to effect electroplating process and form a strong oil repelling treatment layer 5 on the surface of the conical tip end units 3. Viscous ink, guided out of a writing element 4, is prevented from adhering to the tip end unit by the oil repelling treatment layer 5, formed on the outer surface of the opening end 3a of the conical tip end unit 3 whereby the reserving phenomenon of excessive ink can be prevented perfectly. Accordingly, the troublesome phenomenon of dripping of the viscous ink 1 can be prevented and the writing element 4 can be used smoothly and comfortably. On the other hand, the oil repelling effect is high and, therefore, the dripping of the viscous ink can be prevented when the writing tool for big letter, which is provided with a comparatively large opening end 3a, is used.

Title: Solar cell
Inventor: MORITA HIROSHI
IPC: H01L31/0224
Filed: 1984-04-26
Abstract: PURPOSE:To form electrodes being hardly peeled and disconnected by limiting the thickness of plating in accordance with the areas of both the surface and back electrodes. CONSTITUTION:A plating resist 106 is formed to the surface of an Si single crystal substrate to a predetermined shape. A plating layer 107 is formed through Ni electroless plating. A solder layer 108 is shaped onto the layer 107. The thickness of the laye 107 is brought to 0.5-1.2mum in the surface and to 0.8-1.5mum in the back at that time. That is, the peeling of the thickness of an Ni film depends upon the area coverage of the Ni film, and peeling is increased remarkably when the thickness of the Ni film is thickened up to 1.2mum or more in the surface having a small area coverage of the Ni film. On the other hand, the thickness of the film on the back side can be thickened up to 1.5mum because the back side has a large area. The limit of thin thickness is determined within a range that thickness completely covers the irregular surface of the surface of the Si substrate and does not impair conductivity, and the surface side and the back side each extends over 0.5mum or more and 0.8mum or more. Since the back side particularly has a wide area, subsequent solder adhesive properties are deteriorated extremely when thickness does not extend over 0.8mum or more, and plating thickness of 0.8-1.2mum is used as optimum conditions.

Title: Production of wide-band optical fiber coupler
Inventor: HASEGAWA HIDEKAZU
IPC: G02B6/28
Filed: 1991-03-25
Abstract: PURPOSE:To allow stretching without twisting a prestretched optical fiber around an unstretched optical fiber by heating and prestretching the 1st optical fiber and heating and fusing this fiber in parallel with the 2nd optical fiber, then stretching the fibers. CONSTITUTION:The 1st optical fiber 1 prestretched by heating and the unstretched optical fiber 2 are paralleled and the part near the stretching part of the unstretched part of the optical fiber 1 is brought into tight contact with the optical fiber 2. Tension is not applied to the two fibers 1, 2 or the tension as small as not to stretch the fibers is applied thereto and the prestretched part including the unstretched part of the fiber 1 is heated in this state. The heating is executed by moving a heating source 3 back and forth in a fusing region. The part where the nonstretched parts are in tight contact with each other melts first and a fused part is formed. The fused part, then, spreads to the prestretched part and the spacing part is melted as well. All of the prestretched parts are thus fused to the optical fiber 2. The region forming a coupler part is heated and stretched after fusing, by which the optical fiber coupler having desired characteristics is produced.

Therefore, the supply of high voltage or a trigger signal to a pulser is stopped at the time of trouble and the generation of the shock wave of insufficient output due to trouble is prevented. Further, danger such as the occurrence of a fire due to the application of high voltage in the trouble state of the pulser is prevented.

Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a television receiver that receives accurately a teletext signal without being affected by a change in a frequency characteristic of a transmitted television signal. SOLUTION: A television signal including a teletext signal such as a character signal is received by a tuner 2 and a video signal processing circuit 6 reproduces a video signal via an IF detection circuit 3. The video signal is fed to an equalizer circuit 7. Then a teletext decoder 10 decodes the teletext signal from the video signal and a character signal generating circuit 11 generates the character signal, based on the decoded output. Information of a bit error is fed to a channel selection microcomputer 5. The channel selection microcomputer 5 controls an equalizer circuit 7 to change a frequency characteristic of the circuit 7 when a bit error rate is high, based on the bit error information. Thus, the teletext data 10 extracts accurately the data.

Title: Method for observing secondary electron image of insulator
Inventor: SUZUKI YOICHI
IPC: H01J37/28
Filed: 1985-04-18
Abstract: PURPOSE:To prevent electrification of the surface of the insulator sample by heating the sample and adjusting the acceleration voltage to a level for a secondary electron production rate of about 1 during the observation of a secondary electron image produced by irradiating the electron beam on the sample. CONSTITUTION:The accelerated electron beam discharged from an electron gun 1 is focused by a focusing lens 5 and then irradiated on an insulator sample 6. At the same time, the electron beam is scanned by a deflecting coil 8 to produce secondary electrons which are detected by a microchannel plate 9. During the above process, the surface of the sample 6 is heated by an infrared lamp 12 and the voltage for accelerating the electron beam is adjusted to a level for which the rate of production of secondary electrons by the sample 6 becomes about 1. Electrification of the insulator sample 6 is prevented due to minimal variation of the surface electric potential of the sample 6 which results from reduced resistance of the sample 6 resulting from its temperature increase. Accordingly, it is possible to perform image observation over a long time.
