Title: Field-effect transistor provided with deep p-type main-body contact source plug
Inventor: ROBAATO ESU RASAARU
IPC: H01L29/10
Filed: 1993-04-15
Abstract: PURPOSE: To obtain an N-channel field effect transistor(FET) which has high output and a fast switching speed by preventing a parasitic bipolar transistor from turning on in the FET. CONSTITUTION: In a displacement current path between a source electrode 410 above it and the top surface 403 of a substrate 401, a deep P-type main body contact source plug region 416 is provided and extended downward into a P-well 404, toward a channel region 407 below at least part of an N<+> -source region 409. Then the deep P-type main body contact source plug area 416 has a resistance lower than a lightly-doped well semiconductor material, so that a voltage developed below the N<+> -source region 409 as to a specific displacement current becomes low. Therefore, the voltage at the base of the parasitic bipolar transistor is not forward biased easily with respect to the emitter of the N<+> - source region 409, so that tolerance to high-speed voltage variation at the border of the P-well of the drain is obtained.

Title: Vertical deflection circuit
Inventor: YASUDA HIDEYUKI
IPC: H04N3/16
Filed: 1989-04-06
Abstract: PURPOSE:To obtain a vertical deflection circuit not causing distortion of screen by varying a peak value of a vertical deflection voltage automatically in response to the frequency for a vertical blanking period. CONSTITUTION:The circuit consists of a vertical oscillation circuit 1, an amplification shaping circuit 2, a vertical output circuit 3, a deflection coil 4, a pumpup circuit 5, a vertical blanking line detection circuit 6, a discrimination circuit 7 and auto/manual changeover switch 8. Then the frequency of a vertical synchronizing signal is discriminated to switch the peak value of a vertical deflection voltage for the vertical blanking period to be increased. When the video signal whose vertical synchronizing signal frequency is 120Hz is reproduced, for example, since the deflection voltage for the vertical blanking period is increased more than the case with 60Hz, the vertical blanking period is quickened and the display period is prolonged by the share thereby causing no distortion on the screen. Even when the vertical deflection frequency is changed, no distortion is caused on the pattern.

Abstract: PURPOSE:To obtain the surface layer of the titled urethane rubber roll with a very high hardness, prevent the generation of cracks during using and obtain the urethane rubber roll excellent in durability by a method wherein at least the surface layer of the main body of the urethane rubber roll is provided with a thermosetting resin- impregnated fiber layer formed by impregnating thermosetting resin into non-woven or woven fibers. CONSTITUTION:At least the surface layer of the main body of an urethane rubber roll is provided with a thermosetting resin impregnated fiber layer formed by impregnating a thermosetting resin such as urethane rubber, for example, into non-woven or woven fibers. The thermosetting resin impregnated fiber layer is manufactured by a method wherein the liquid thermosetting resin is dripped on the non-woven or woven fiber tape to impregnate it while rotating a roll core. The non-woven or woven tape, impregnated with the thermosetting resin, is wound until a predetermined thickness is obtained enough to form the thermosetting resin impregnated fiber layer. The surface layer of the roll is made of a fiber reinforced layer impregnated with the thermosetting resin, therefore, generation of cracks may be prevented even when the roll is employed under the condition of a large load and a high speed rotation. Even when a fine crack, for example, is generated, the crack will never be enlarged suddenly.

Title: Method and equipment for word column recognition
Inventor: BUORUKERU SHIYUTAINBISU
IPC: G10L15/05
Filed: 1995-04-14
Abstract: PURPOSE: To make a threshold with respect to an evaluating value more preferable and to reduce the number of active hypotheses. CONSTITUTION: When it is necessitated to use a language model for recognizing a speech signal and vocabularies are constituted as a tree, a language model value can not be considered before the final point of words. As the evaluating value is ordinarily improved after the final point of each word by the part of a language model value, it is necessitated to improve the threshold with respect to the evaluating value to be finished by a hypothesis. Consequently, many invalid hypotheses remains as active ones in a long period. Then a correcting value is added to an evaluating value with respect to the at least a part of the nodes N0, N1,... of the vocabulary tree lest the sum of correcting values on a route to the final point of the word becomes larger than a language model value with respect to this word.  As the result, the evaluating value of all the hypotheses become equal in size with respect to each inspection signal. Upon reaching the final point of the word, the sum of all the added correcting values is reduced and a correct language model value is added.

Title: Arc welding method
Inventor: MORIYASU MASAHARU
IPC: B23K9/02
Filed: 1983-05-20
Abstract: PURPOSE:To perform profiling of a weld line with high accuracy by moving circularly a torch, moving rotationary an arc, detecting and processing the current change during the rotation, determining the lateral deviation of the arc and controlling the position of the torch until said deviation is made zero. CONSTITUTION:A torch 51 is rotationally oscillated to move rotationally an arc 8 and a signal indicating the change in current or voltage is passed through a filter having a cutoff frequency of about the rotating frequency of the arc. Whether the position where said change arises is forward F or backward B in the advancing direction is identified from the comparison of the 1st prescribed values past the filter with each other and whether said poisition is on the left L or right R is likewise identified from the comparison of the 2nd prescribed values with each other, by which the lateral deviation of the above-described signal is detected. The position of a welding torch is thereafter controlled until said deviation is made zero and the follow-up of the weld line is accomplished. The automatic follow-up of the weld line with high accuracy with the arc itself as sensor is thus made possible and there is no directivity in the detection. The above-mentioned method is applicable to a robot.

Title: Electrophotographic recorder
Inventor: ISHIJIMA HIROYASU
IPC: G03G15/01
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To suppress the decrease of transfer efficiency and to prolong the life of an intermediate transfer body by previously storing the current value or voltage value of the intermediate transfer body, at which the transfer efficiency for a recording medium of the intermediate transfer body becomes highest with respect to each of plural surface resistance values of the intermediate transfer body and controlling a current or a voltage supplied to the intermediate transfer body, so as to make the transfer efficiency highest with respect to each surface resistance value.

In a secondary transfer process, the secondary transfer roller 8 brings the recording medium into press-contact with an intermediate transfer drum 6 and the low-current source 21 causes the current to flow in the intermediate transfer drum 6, with the secondary transfer roller 8. A voltage detector 22 detects the voltage value applied to the drum 6. A current controller 23 controls a constant current outputted by the constant current source 21, so as to obtain the transfer efficiency of the drum 6 being most suitable for the recording medium 7, with respect to the voltage value detected/ outputted by the voltage detector 22, based on this voltage value.
