Title: Starter device
Inventor: ZENMEI KEISAKU
IPC: F02N15/02
Filed: 1994-09-13
Abstract: PURPOSE: To reduce the size and weight of a motor part of a starter device by fitting a cylindrical stopper to the inner peripheral part of a front bearing, and disposing a stopper fixing ring groove for an output shaft in front of the front bearing. CONSTITUTION: A ring 22 fixing groove 23a for fixing a stopper 21 at its front end part is disposed in front of a front bearing 16. The stopper 21 is cylindrical and fitted to the inner periphery of the front bearing 16.

Accordingly, the diameter under the pinion can be reduced, the pinion bottom is ensured, and it is possible that if the module is 2.54, the number of teeth is 7, and if the module is 2.117, it is 8. The stopper 21 is elongated in the axial direction, and the front bearing 16 is supported by the stopper 21.

Title: Voltage comparing circuit
Inventor: TOSAKA TAKAO
IPC: G01R19/165
Filed: 1986-10-17
Abstract: PURPOSE:To simplify circuit constitution by reducing the number of elements used for the sake of providing hysteresis function, by using a multicollector transistor performing reverse operation. CONSTITUTION:In a voltage comparing circuit having hysteresis function, a multicollector transistor Q7 performing reverse operation, that is, allowing an emitter to function as a collector and the collector to function as the emitter is used in an output stage. The transistor Q2 takes out the change in the current of a transistor Q2 as output OUT and changes the voltage dividing ratio of resistors R1-R3 on the basis of the ON/OFF operation of the transistor Q2 to allow comparing voltage Vref to change to provide hysteresis. By this method, since the emitter earth current mu-factor of a reverse direction characteristic is high at the time of saturation, even when one collector of the transistor Q7 is saturated, the current between the base and collector thereof may be reduced. Since the base current does not become insufficient, a conventional balance resistor can be made unnecessary. Further, because of multicollector output, it is unnecessary to provide a plurality of output transistors.

Title: Graphic editing device
Inventor: MORITA KOJI
IPC: G06F17/50
Filed: 1987-09-30
Abstract: PURPOSE:To copy out a bond graph in a short time by automatically outputting the bond graph to a display device based on a bond graph element for generating the bond graph inputted from an input device and a rule stored in a storage device. CONSTITUTION:An operator selects elements contact point from a bond graph display menu D2. The operator generates the elements 1 and the contact points 2 by suitably selecting a display operation menu D3 and an element/contact point menu D4. When the generation of the elements/contact points terminates, a system returns to an initial step. The operator selects 'bonds' by the bond graph display menu D2. Thus, the system shifts from a selection branch to the next step, the operator selects 'drawing' from the display operation menu D3 and selects the 'elements' or the 'contact points' which come to both ends of the bonds by a mouse 13 or the like, whereby the bonds 3 are generated. Thus, the bond graph without 'arrow mark' and 'strokes' can be generated.

Title: Method and optical sensor for detecting presence or absence of powder in container
Inventor: MURATA NAOKI
IPC: G01S17/88
Filed: 1983-12-26
Abstract: PURPOSE:To make it possible to detect the presence or absence of the powder in a container by certainly receiving emitted light, by simple constituion such that a light pervious spacer is provided to the head surface of a reflective sensor having a light emitting part and a light receiving part mounted to the head surface thereof. CONSTITUTION:A transparent spacer 5 is embedded in a reflective sensor 1 and closely contacted with terminal surfaces of optical fibers 2, 3. A head 6 is attached to the side wall of a container and, when the powder in the container is contacted with or slightly separated from a detection surface, light L emitted from the optical fiber 2 transmits the transparent spacer 5 and reflected by the surface of the powder to be received by the light receiving fiber 3. As mentioned above, because the spacer 5 is provided to the head surface of the sensor 1, emitted light is certainly received even if the head surface is covered with the powder and it is unnecessary to coincide the center line of a light emitting and receiving head and the presence or absence of the powder can be certainly detected by simple constitution.

Title: Projection optical system and manufacture of semiconductor device thereby
Inventor: SUZUKI MASAYUKI
IPC: H01L21/027
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To enable a projection optical system to be easily corrected on aberrations caused by deformation of a beam splitter when the beam splitter is small in thickness by a method wherein the beam splitter is so arranged as to make a normal line of the surface of the beam splitter nearly coincident with the direction of gravity. SOLUTION: A divergent light flux projected from a point located on a reticule 1 is made to penetrate through a beam splitter 3 passing through a lens 2. A transmitted light flux passes through a first quarter wavelength plate 4 and then travels reversely as reflected from the concave surface 5a of a concave mirror 5. Furthermore, the reflected light flux traveling reversely is made to travel as turned in a traveling direction by an angle of 90 deg. to pass through the quarter wavelength plate 4 again. Furthermore, a light flux is made to pass through a second quarter wavelength plate 6 and turned into circularly polarized light, and the circularly polarized light is made to form an image on a wafer 8.  The thickness of the beam splitter 3 is set below 1/20 as large as its maximum effective diameter, so that the beam splitter 3 is much deformed by its own weight, but a normal line of the surface of the beam splitter 3 is set, nearly parallel with the direction of gravity, so that the beam splitter 3 is deformed symmetrical about its center. Therefore, a projection exposure system of this constitution can be easily corrected on aberrations caused by planar deformation of a beam splitter.

IPC: G11B5/127
Filed: 1984-11-26
Abstract: PURPOSE:To improve the magnetic permeability in a high-frequency region by assembling a magnetic head with a thin amorphous magnetic sheet subjected to a heat treatment for removing the intrasurface anisotropy as a core material and subjecting the same to the heat treatment in the static magnetic field in the specified direction along the main plane of the thin amorphous magnetic sheet. CONSTITUTION:The thin amorphous magnetic sheet is subjected to water quenching as a pretreatment at and for the temp. and time selected to maximize the magnetic permeability mu. The magnetic head is assembled by using such thin amorphous magnetic sheet as the core material. Such magnetic head 4 is disposed between both poles, i.e., an N pole 5 and an S pole 6 and is subjected to the heat treatment under the prescribed magnetic field impressed thereto. The magnetic head 4 is so disposed that the main plane of the thin amorphous magnetic sheet 1 and the direction of the magnetic field are made parallel with each other. The effective magnetic permeability mue in the direction perpendicular to the direction of the impressed magnetic field is improved when the magnetic head is subjected to the heat treatment in the static magnetic field in the above-mentioned manner. The effective magnetic permeability is improved by executing both of the water quenching as the pretreatment and the heat treatment in the static magnetic field.
