Title: Electrophotographic apparatus
Inventor: SUZUKI KOUJI
IPC: G03G21/14
Filed: 1978-08-23
Abstract: PURPOSE:To obtain accurate measurement and enable stable image formation to be obtained by mounting a detecting device for surface potentials at the accurate distance and accurate angle with respect to a photoreceptor through the use of the positioning hole and guide part provided to the housing. CONSTITUTION:An electrometer M for measuring latent image potentials is mounted between a full surface exposure lamp F and a developing device G to measure the latent image potentials before development. The output of the electrometer M enters a synchronous clamping circuit O, where it is converted to the DC signal by the synchronizing signal generated in a synchronizing signal generating circuit Q. This signal is then integrated R and is applied to a sample holding circuit S. S extracts and holds the amplitude component of the integrating circuit R at the specified timing signal applied to therminal T. This output having been held is applied to the developing device G after amplification U and the potential differences are controlled constant so that the development suited to the latent image potentials is accomplished. Since the use of a light source other than that for original exposure is used as a light source for exposure for the purpose of latent image potential measurement, the degradation in the copying images accompanied with the environmental changes and aging of the charge characteristics of the photosensitive drum may be prevented.

Title: Brake power control device for vehicle
Inventor: AIZAWA HIDEYUKI
IPC: B60T8/58
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To perform control of a brake power to an optimum value even at a very low μ road and to prevent the occurrence of engine stalling by a method wherein when it is decided by a very low μ road deciding means that a road is a very low μroad, application of a brake power on at least one wheel is limited by an automatic brake control means. SOLUTION: An electronic control device 50 controls the opening states of on-off valves 24, 28, and 34 and the wheel speeds of front and rear wheels are respectively car wheel sensors 52 and 54. Based on signals from the sensors, the wheel speed of a driven wheel and a drive wheel on the same side are compared with each other. When the wheel speed of the driven wheel is lower than that of the driven wheel by a given value or more, the electronic control device is functioned as a very low μ road deciding means to decide that a road is a very low μ road. Namely, the wheel speeds of right and left rear wheels (the driven wheel) are compared with each other and, for example, when the wheel speed of the left rear wheel is higher, the wheel cylinder pressure of the left rear wheel is held, and a brake power is limited to prevent the occurrence of locking. Finally, by limiting brake on a wheel having a highest wheel speed, and a fall of a wheel speed is prevented from occurring.

Filed: 1995-04-04
Abstract: PURPOSE: To prevent the occurrence of various harmful influences such as carrying failure of a document and the deterioration of reading accuracy due to a waving part generated in an endless belt at driving time. CONSTITUTION: A screen backing member 18 is provided to back a stretching side part 20a of a screen sheet 20 from its inside. A U-shaped deviation preventive part 18c to pass the side end of a loose side part 20b when the screen sheet 20 is stretched between rollers 13 and 14, is arranged in its backing member 18. The deviation preventive part 18c is arranged so that guide surfaces 30 are opposed by opposing respective opening parts to each other. When the screen sheet 20 deviates, the side end of the loose side part 20b strikes on the guide surfaces 30, and prevents deviation more than that. However, since looseness exists here, its loose side part moves so as to run along a roller circumferential surface according to rotation of a driven roller, and is flatly leveled there, and waving is eliminated, and it transfers to the stretching side as it is in an unwaving flat condition.

Title: Commutatorless motor
Inventor: NAGAI NOBUYUKI
IPC: H02K29/00
Filed: 1978-08-25
Abstract: PURPOSE:To prevent the delay in the detection of rotation phase of a rotor, by providing a magnetic sensor for detecting the rotation phase and by placing the magnetic sensor nearer by a prescribed angle nearer to a motor coil than a conventional magnetic sensor. CONSTITUTION:The rotation phase of the rotor 1 is detected by the magnetic sensor 6. In a conventional case, the magnetic sensor would be placed with an angle difference theta0 from the motor coil 7 in the rotating direction R of the rotor 1. Therefore, the rotation phase of the rotor would be detected with an angular lag DELTAtheta. The angle difference thetao is represented as thetao=360/2P(1-2/N) where P denotes the number of poles of a field system 5 and n denotes the number of phases of the motor. According to the present invention, the magnetic sensor 6 is located at an angle theta which is larger than zero but less than thetao. The delay in the detection of the rotation phase is thus prevented.

Title: Semiconductor device
Inventor: NAITO MASAMI
IPC: H01L29/78
Filed: 1995-04-27
Abstract: PURPOSE: To suppress the increase of the on-resistance by prescribing the spacing between deep base layers. CONSTITUTION: In a DMOSFET having a groove formed, a deep p-base layer 72 is formed under a channel p-base layer 16. This deep p-base layer 72 is formed such that an intersection of the end of the deep p-base layer 72 and the bottom part of the channel p-base layer 16 is located between the end of the bottom part of the channel p-base layer 16 and an intersection positioned under the end of the bottom part of an n<+> -type source layer 4 within the channel p-base layer 16. Thus, because the spacing between the deep p-base layers 72 is made larger, the on-resistance can be made lower. Further, a base region formed under the n<+> -type source layer 4 is made wider, resistance in this part becomes smaller so that a larger surge resisting amount can be achieved.
