Title: Ignition coil-integrated distributor
Inventor: KOSHIDA RYOICHI
IPC: F02P15/00
Filed: 1987-06-23
Abstract: PURPOSE: To prevent the adverse effect of the ignition coil leakage magnetic flux on a rotation signal generating means by providing field magnets made of a magnet member with the magnetic resistance characteristic and generating the magnetic flux for detecting the rotation signal at the position of a pickup coil of a magnetic circuit.  
     CONSTITUTION: When the magnetic flux for detecting the rotation signal is generated multiple field magnets 13, 14 together, this magnetic flux passes a magnetic circuit M constituted of a stator core 12, a signal rotor 8, a distributing shaft 4, and a movable base 10. When a pickup coil 15 detects the change quantity of the magnetic flux changed as the signal rotor 8 rotates, an ignition amplifier 19 controls the current flow from a battery to the primary coil of an ignition coil 17 in response to the output signal of an electromagnetic pickup 15'. In this case, the second field magnet 14 is arranged at the position of the pickup coil 15 of the stator core 12. The function of the magnetic gap against the leakage magnetic flux from the ignition coil 17 is thereby obtained.

Title: Yellowish-brown-colored glass and its production
Inventor: SATO SATOYUKI
IPC: C03C4/02
Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To produce yellowish-brown-colored glass the demand for which is great and which is also capable of removing ultraviolet rays from the entering light, using greenish or blackish cullet as a main raw material and accordingly to promote the demand for such greenish or blackish cullet. SOLUTION: This production process comprises: melting a batch containing greenish cullet of >=90 wt.% and a reducing agent; and thereafter gradually cooling the molten batch; wherein the SO3 content in the resulting glass is adjusted to 0.01-0.1 wt.% and by effecting such a reduced state of the glass, the glass has a yellowish brown color. Since a bottle formed from such yellowish-brown-colored glass is capable of removing ultraviolet rays from the entering light and the demand for such bottles is great, the demand for greenish or blackish cullet can be promoted.

Filed: 1994-07-06
Abstract: PURPOSE:To provide a real stereoscopic effect by separating an image on an pixel formation sheet to upper/lower and left/right images through two sheets of lenticular plates and displaying a stereoscopic image. CONSTITUTION:An upper side lenticular plate 30 and a lower side lenticular plate 20 are designed and arranged so as to focus on the surface of the pixel formation sheet 10 downward. Pixels A1-D4 in matrix reconstituted from the image having parallax in upper/lower and left/right matching with the characteristics of two sheets of lenticular plates 30, 20 are formed on the pixel formation sheet 10. In such a case, an observation optical path of a right eye 1 shown by a dotted line passes through the lenticulars 30, 20, and arrives at the pixel B1 on the pixel formation sheet 10. Similarly, the observation optical path of a left eye 2 shown by a solid line arrives at the pixel C1 on the pixel formation sheet 10. In such a manner, since the right eye 1 and the left eye 2 observe the different images having parallax respectively, an observer obtains the stereoscopic effect.

Abstract: PROBLEM TO BE SOLVED: To make good use of a heterojunction having a function for preventing minority carriers from being injected and to provide a bipolar transistor with high speed operation, a diode or an I<2> L suitable for mass production. SOLUTION: An MQB layer 10 as a multiple quantum barrier in a super lattice structure is formed at a position near a base/collector junction on the side of an Si collector layer 3 in a heterobipolar transistor. In the superlattice structure, a well layer 10a and a carrier layer 10b as ultrathin films with different compositions are laminated alternately. As a result, a barrier height is effectively increased through a reflective effect with respect to carriers, and minority carriers from an SiGe base layer 4 can be prevented from flowing into the Si collector layer 3. As a result of this, the injection of the minority carriers can be prevented through the MQB layer 10, and by reducing the accumulated amount of minority carriers, the operational speed can be increased.

Filed: 1983-08-24
Abstract: PURPOSE:To intensify the radiant heat by constituting the reflection plate in such a manner that a reflection plate has on its lower surface a planar heater and at its central part a suction port, and air sucked up to the sides of air feed fans from the suction port is blown out from the peripheral sides of the reflection plate. CONSTITUTION:The heat generated in the planar heater 20 radiates downwardly and, at the same time, heats the reflection plate 14 and is sucked up through suction holes 15 to warm air blown out of an air feed path 19b via a fan chamber 19a. In this case, the air stream is sucked from the central part of the lower surface of a protective cover 23, thus passing through suction holes 15 and being sent out to the peripheral side of the reflection plate 14 by means of the air feed fan 16. Hence, the heat generated in the planar heater 20 and transmitted to the reflection plate is absorbed in the form of uniform hot wind from the peripheral edge of the protective cover 23. by the above construction, wind does not directly hit the planar heater, and the radiant heat can be effectively utilized without being heated and room heating can be carried out by the uniform hot air flow.

Abstract: PURPOSE:To easily disassemble and assemble the spring device by restricting a free extension of a spring when the spring body is separated from pistons. CONSTITUTION:When a valve 10 is opened, pistons 18a, 18b ascend to push up a spring bearing 30. And inside peripheral projection 29 of the spring bearing 30 is located above a spring presser sleeve 27. When the value 10 is closed, a piston 18 is lowered by the force of a spring 32.

Title: Manufacture of semiconductor light emitting device
Inventor: BITO YOSHIFUMI
IPC: H01L33/34
Filed: 1991-05-30
Abstract: PURPOSE:To reduce defective crystallization in an LED and improve the light emission characteristics by varying the degree of distortion of a distorted superlattice layer formed in a buffer layer in the direction of growth and locating the largest deformation below the upper end of the direction of crystal growth. CONSTITUTION:In each distorted superlattice layer 14 and 15, the first semiconductor crystals 14a and 15a and the second 14b and 15b are alternately grown a plural number of times. The lattice constant of the first semiconductor crystal is different from that of a semiconductor crystal 3A, a major component of a buffer layer 3a; and the lattice constant of the second SC crystal differ from the that of the front SC crystal. Therefore, the distortion of distorted superlattice layers 14 and 15 becomes smaller in the direction of growth; and the distortion is the largest at the lowest end of the direction of growth. Distortion is reduced because the distortion of the distorted superlattice layers 14 and 15 is smaller at the upper side of the direction of growth; and it effectively confines dislocations in the buffer layer 3 or releases them horizontally since the distortion is the largest at a place lower than the upper end of the direction of growth.
