Title: Electric railcar with regenerative brake
Inventor: OSUMI NAOTAKE
IPC: B60L7/10
Filed: 1987-03-13
Abstract: PURPOSE:To operate a regenerative brake effectively even under light load by qualifying the reference value of regenerative annulment in response to order from the lead car of one carriage of electric railcars. CONSTITUTION:The order of each electric railcar or unit is detected by a logical circuit by a straight-pull circuit 21 at every car, and a flag of order of interest is set. A regenerative-annulment reference-value setting circuit 300 sets a reference value corresponding to the flag from a car order detector 10. On the other hand, feeder voltage through a pantograph 60 from a stringing 50 is detected by a stringing voltage detector 40. When feeder voltage is brought to the reference value or more, a comparator 70 annuls a regenerative brake by a regenerative-brake changeover circuit 80. Changeover to another brake from the regenerative brake is conducted simultaneously by a brake controller 90.

Title: Optical system
Inventor: KOMATSU YASUTOSHI
IPC: G01S17/58
Filed: 1993-03-17
Abstract: PURPOSE:To enhance stability in the oscillation mode of laser light source by suppressing interference between an emitted light and a reflected light. CONSTITUTION:A wavelength plate WP1 having optical path difference of lambda/4+nlambda is disposed between a laser light source LS and an object S so that an optical beam emitted from the laser light source and an optical beam returning back to the laser light source intersect perpendicularly to each other (with phase of lambda/2+2nlambda) thus preventing interference. Furthermore, a wavelength plate WP2 having optical path difference of lambda/4+ (2m+l)lambda/2 is disposed between a light receiving optical system RE and the object S in order to convert a circularly polarized light from the wavelength plate WP1 into a linearly polarized light thus performing characteristic processing of incident light smoothly. (lambda represents the wavelength of laser light, n and m are arbitrary integers of O or above).

Abstract: PURPOSE:To manufacture an element, wherein contamination is small and drain resistance is low, by self-alignment, by sequentially removing Al evaporated on the entire surface, implanting ions with a formed gate electrode as a mask, then etching a wiring pattern. CONSTITUTION:Al 1 is evaporated on the entire surface of a substrate on which source and drain diffused layers 3 of both N and P channels and an oxide film are provided. Then, Al 1 on the P channel is photoetched so that it is overlapped on the end parts of the diffused layer 3. Thereafter, the resist is removed, the gate for the P channel is formed, and P type impurities 5 are implanted with the gate as a mask. Likewise, Al on the N channel is removed and N type impurities are implanted. The amount of ion imlantation is so determined as to form a P<+> region in the P channel part in consideration of activation. Then Al 1 is etched so that the wiring pattern is remained intact. Thus, the self-alignment can be performed with Al as a mask, and an MOSFET wherein the contamination is small and the drain resistance is low can be formed.

Title: Complete contact type read sensor and read sensor assembly
Inventor: NAGATA TATSUYA
IPC: H01L27/146
Filed: 1988-03-14
Abstract: PURPOSE:To improve the read performance of a complete contact sensor by mounting a conductive transparent film deformed elastically easily on a sensor substrate. CONSTITUTION:When the sensor substrate 1 is lighted from the rear face with a light source 5, the lighting light transmits through the sensor substrate 1 and the conductive transparent film 6 to light an original 7. The radiated light 11 is reflected with an intensity in response to the degree of black/white level of the original 7 and made incident on a sensor element 1a. Thus, an optical current proportional to the luminous quantity flows through the sensor element 1a and the original 7 is read by detecting the signal. When the read of one line is finished, a platen roller 8 is rotated to feed the original. Since the original 7 and the film 6 are rubbed together, a static electricity is generated. Thus, even if noise is induced in the sensor element 1a or the circuit wiring, since the induction is shielded, a stable output is obtained.
