Title: Distance measuring device
Inventor: FUJIWARA YOSHIMASA
IPC: G01S17/08
Filed: 1982-12-29
Abstract: PURPOSE:To vary an incident light quantity to each photodetector by a movement of a condensed point of a reflected light corresponding to a distance to a point to be measured, from a lens, by making a light incident to one photodetector and the other detector by a total reflecting surface in a pin-hole mirror, and a pin-hole. CONSTITUTION:A reflected light is focused by a lens 3, and a pin-hole mirror 4 is inclined and installed between a condensing lens 15 and a photodetector 5 installed on an optical axis of the reflected light, and the lens 3. The pin-hole mirror 4 has a total reflecting surface and also has a pin-hole at the optical axis position of the reflected light. When a point to be measured is at a distance D+DELTAD, a condensed point P by the lens 3 of the reflected light is a pin- hole in the pin-hole mirror 4, and accordingly, the reflected light is all made incident to the photodetector 5. Therefore, a normalized output VA/(VA+VB) in the operating part becomes ''1''. When the distance to the point to be measured becomes short, as for the position of the condensed point P, a light which does not pass through the pin-hole in the pin-hole mirror 4 is reflected by the total reflecting surface and made incident to the other photodetector 6. Accordingly, a value of VA/(VA+VB) becomes small.

Title: Discharge lamp lighting device
Inventor: SHIICHI HIROYASU
IPC: H05B41/18
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To adequantly set pulse voltage at the time of starting in accordance with the shape of a discharge lamp, by constituting a lighting device so that the size of pulse voltage, generated by a pulse voltage generating means, can be variably set optionally from outside. SOLUTION: Charging voltage for pulse capacitor 5c can be controlled, by optionally setting pulse voltage when a discharge lamp 32 is started, by means of the first - third setting switches 8a-8c of a shape setting means 8 for a discharge lamp. Applying the charging voltage to the primary coil of a transformer 5a through a thyristor 5b can sdequately set the pulse voltage in accordance with the shape of the discharge lamp 32, thereby obtaining an inexpensive lighting device without the restriction of the shape of the discharge lamp 32. Since D.C. voltage is to be supplied to the discharge lamp 32 before pulse voltage AP, BP, and CP is genetated, and low-frequency voltage is to be supplied direct after a given time elapses after the pulse voltage is generated, the discharge lamp 32 hardly goes out to ensure stable lighting.

Title: Apparatus for diagnosing potential difference type electric heating exhaust gas sensor for controlling combustion process
Inventor: SCHNAIBEL EBERHARD
IPC: G01N27/409
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To make surely diagnosable an electrical error by outputting an error signal even when a sensor signal is temporarily separated from a third range after the change of an electrical heating current is generated within a predetermined maximum time. SOLUTION: The sensor voltage of the sensor apparatus 4 leaves an upper and low limit value range (zone) at a point t1 of time after heating to be in an operable state and a sensor signal is cyclically alternated between a first range of a high signal value and a second range of a low signal value by the control of a controller 2.5. When this signal is present within a third range separating both high and low signals for a period longer than the predetermined max. time, sensor signal line breakdown 1.8 can be certainly detected. However, when the breakdown of a sensor earth line 1.9 is generated, capacity coupling 1.6 is formed by the action of a sensor heater 1.4 to generate a voltage peak. At this time, since sensor voltage is out of the third range, an error can not be detected by known diagnosis. Since the sensor voltage is again present in the zone about 20 ms after the elapse of a voltage peak in this sensor, an error can be detected.

Title: Vertical mos fet
Inventor: KITAHIRA YASUO
IPC: H01L29/06
Filed: 1988-09-19
Abstract: PURPOSE:To avoid the deterioration of a breakdown strength at the corner of a channel part by a method wherein P-type diffused regions are formed into a lattice pattern so as to have P-N junctions composed of the corner parts of the channel parts form recessed curved surfaces and gate electrodes are formed into independent island patterns. CONSTITUTION:As a channel part is formed inside a gate electrode 15 formed into an island pattern, a P-N junction at a square corner part has a shape bent inward and hence a depletion layer 21 formed from the P-N junction toward an epitaxial layer 12 also has a shape along the shape of the P-N junction. With such a shape, an electric field from the epitaxial layer 12 to a P-type diffusion region 13 is not concentrated and distributed along the recessed curved surface of the depletion layer 21. Therefore, the breakdown strength of a MOSFET is determined only by a punch-through or Zener breakdown voltage in the channel part along the side of the gate electrode 15 and the deterioration of the breakdown strength at the corner is avoided. As a result of lattice formation of P-type diffusion regions 13, the corner parts of the deep parts of the P-type diffusion regions 13 also have recessed curved surfaces, so that the deterioration of the breakdown strength can be avoided.

IPC: H04B10/03
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To detect a narrowered transmission wavelength interval between slave stations with high accuracy and high responsiveness and to keep the transmission quality over a long period. SOLUTION: In this system, an optical intensity modulation signal having different subcarrier frequencies from slave stations 2a-2c and sent in different sets of wavelength λa-λc is sent through by an optical transmission line 3 adopting an optical fiber to a single master station 1. In this case, the wavelength of each slave station is changed regularly and the master station uses a detector A5 to detect a noise amount and its change at a frequency band and the master station changes a wavelength of each slave station sequentially when it is predicted that the deterioration in the transmission quality caused by beat noise increase by approach of the wavelength interval takes place based on the detected amount.  Or the noise amount and its change at a frequency band at each occasion are detected and compared to discriminate a slave station whose beat noise is increased and the master station allows the slave station to set the wavelength again, then the transmission quality is maintained.

Title: Variable speed induction motor
Inventor: SATAKE TOSHIHIKO
IPC: H02P23/00
Filed: 1989-09-09
Abstract: PURPOSE:To permit the employment of the title motor for an apparatus having any load characteristic by a method wherein one stator coil is short-circuited while the other stator coil is provided with the rotary magnetic field of reverse phase upon braking. CONSTITUTION:When signals are outputted from a signal outputting means, not shown in a diagram, into relays 52, 53, 55 in the connection of normal rotation, which is shown in the diagram, to flick switches M4, M5, the phase of one of stator coils becomes the opposite one by the switch M4 while the connection of a motor becomes Y-connection by the switch M5. On the other hand, the power supplying terminals of the other stator coil are short-circuited in the condition of  -connection as it is by the switching of switches M6, M7 and, therefore, an electromotive force is generated by the rotation of a rotor 7. The electromotive force, thus generated, is consumed by the conductor resistance of the short-circuited stator coil and the like. In this case, a braking torque is changed variously by the pivoting of a pivoting stator. One stator coil is short-circuited and the power source of reverse phase is supplied to the other stator coil in such a manner that a variable speed induction motor, capable of coping with all kinds of load torques, is obtained.
