Title: Photosensor
Inventor: KATSURADA NORIHIKO
IPC: G01V8/14
Filed: 1989-03-10
Abstract: PURPOSE:To expand an area of detection by a method wherein a radiant light from the focus of a paraboloidal reflector for radiation is reflected to be horizontal lights by the paraboloidal reflector for radiation and the horizontal lights are reflected by a paraboloidal reflector for reception to be converged in the focus thereof. CONSTITUTION:A radiant light from an optical fiber 4 for radiation is reflected to be parallel lights by a paraboloidal reflector 2 for radiation, since the fore-end face of the optical fiber 4 for radiation faces the position of the focus F1 of the paraboloidal reflector 2 for radiation. On the other side, all the aforesaid parallel lights are reflected by a paraboloidal reflector 6 and converged on the fore-end face of an optical fiber 8 for reception, since the fore-end face of this fiber 8 faces the position of the focus F2 of the paraboloidal reflector 6 for reception. Accordingly, the radiant light from the optical fiber 4 for radiation can be transmitted efficiently to the optical fiber 8 for reception. Besides, the aforesaid parallel lights form a band of light of a prescribed width in the axial direction of the central axis O, while they once converge on the central axis O within the same plane and then expand again. When an object of detection is set on the central axis O of a detecting element 12, therefore, the degree of resolution is improved remarkably.

Title: Signal detecting method
Inventor: UKITA HIROO
IPC: G11B7/13
Filed: 1987-03-14
Abstract: PURPOSE:To reproduce optically recorded information with a high SN ratio by setting up a semiconductor laser at a low reflection factor part of an optical recording medium to a natural radiation state, setting up the semiconductor laser at a high reflection factor part to a laser oscillation state and detecting the quantity of light in both the states by a photodetector. CONSTITUTION:Naturally radiated light 40 from the semiconductor laser 1 is radiated to the optical recording medium 4 having the high reflection factor part and the low reflection factor part, reflected light 41 from the medium 40 is made incident upon a light emitting layer of the laser 1, and when the medium 4 has a high reflection factor, the laser 1 is turned to the oscillation state by the reflected light to detect the existence of the laser oscillation state. Thus, an avalanche resonance state oscillating the semiconductor laser like avalanche on the basis of natural radiation beams radiated from the laser 1 and reflected by the part having the high reflection factor and the no-laser oscillation state of the semiconductor laser 1 based upon the reflected light from the part having the low reflection factor are detected. Since an area having large noise at a part near the oscillation threshold of the laser 1 is not used by using said method, the SN ratio and signal modulation can be improved.

Abstract: PURPOSE:To reduce possibility of attaching of bubbles to a side etch section, that is, an overhang section by performing side etching through dry etching or wet etching by the use of an etchant of a low viscosity. CONSTITUTION:A first polysilicon film 18 exposed inside a CVD oxide film 22 is entirely removed (side-etched) through dry etching by a chlorine gas or a gas containing fluorine and chlorine, etc. At this time, an overhang section by a second polysilicon film 20 is formed in an area near an emitter formation region and a collector removal region formation region. In this case, first and second heat oxide films 17, 19 are not etched abnormally. Furthermore, since polysilicon is etched in side etch of the first polysilicon film 18, it is possible to carry out even wet etching with a mixture liquid of hydrofluoric acid and nitric acid of a low viscosity. Thereby, possibility of attaching of bubbles to the overhang section can be reduced.

Title: Foil decorating method and molding tool used for foil decorating
Inventor: NEZU MICHIKO
IPC: B29L9/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To carry out the manufacturing of moldings with individually different hole specifications such as the presence of a hole, its position and shape using a common molding tool by making protruding parts corresponding to holes freely attachable to and detachable from the tool and performing the attaching/detaching operation of an arbitrarily selected freely attachable/detachable protruding part. SOLUTION: A decorative sheet S is deposited on a pair of one force 3 and the other force 4 of a molding tool with freely attachable protruding parts 2 corresponding to holes 1 in moldings Ma. Then both forces 3, 4 are clamped so that the decorative sheet S is pinched between both forces 3, 4 at positions against the protruding parts 2 and thereby, a resin is prevented from finding its way into a gap between the forces 3, 4. Thus the moldings Ma with the decorative sheet S laminate-bonded on the surface of the moldings Ma so as to even wrap the holes 1 are obtained simultaneously with a molding step. The protruding parts 2 are provided, in a freely detachable manner, on the force 3.  When manufacturing moldings Mb which are of the same outer shape as the molding Ma as a whole but are different from the moldings Ma depending upon whether there are the holes 1, the protruding parts 2 which are positioned on the part requiring no holes 1 and are installed in a freely detachable manner, are removed from the force 3 and the resin is molded to obtain the moldings Mb.

Abstract: PURPOSE:To collect the sounds of only desired directions, by obtaining the outputs of the microphone units featuring the equal sensitivity and arranged on a straight line through the high-speed and sequential switching by means of the change-over switch. CONSTITUTION:Plural units of microphone unit 4 featuring the equal sensitivity are attached to mike attachment plate 3 and arranged on straight line. One electrode of unit 4 is connected to each fixed contact 6 of change-over switch 5, and then mobile contact 7 is turned in a high speed. Thus the output of each unit 4 is obtained in sequence and through the high-speed switching. Here PA is defined in case the sound is applied vertically to the linear arrangement of units 4 along with PB defined when the sound is applied in parallel respectively. Now if the sound is applied from the direction of PA, the outputs of a'-i' of unit 4 are extracted sequentially with delay of each sampling time. On the other hand, if the sound is applied from the direction of PB, the outputs of a'-i' feature the same level at all times. Thus only the sounds arriving from the direction of PB can be collected by extracting the output when the coincidence is secured among the outputs of units 4 and at one sweep.

Title: Lifting device
Inventor: FURUMOTO YOSHIHISA
IPC: B66F7/00
Filed: 1989-03-13
Abstract: PURPOSE:To apply always uniform spring force to each winding member by applying the rotation power of a rotating spring unit to a lifting base via an output shaft, a plurality of prime-mover drums fixed to same and the winding members delivered from the drums. CONSTITUTION:A load corresponding to the weight distribution of a lifting base 4 is applied to each winding member 17. In this case, even if winding members 17 on a light load side are about to be wound up onto prime-mover drums 16, this action is simultaneously transmitted to other prime-mover drums 16 via an output shaft 15. Therefore, the winding members 17 are always unwound onto or delivered from the prime-mover drums 16 each by equal quantity with a uniform unwinding/delivering force. Hence, any lopsided weight distribution can be absorbed by the simultaneous rotation of a plurality of prime-mover drums 16.

Abstract: PROBLEM TO BE SOLVED: To provide a confluence method to same path which enables a drafting person to obtain the method closer to a scenario as intended. SOLUTION: An equation of motion is drafted individually for a main moving object and a sub moving object. The respective equations of motion are solved to calculate time at the starting points of the same action (step 1) and a time difference is determined at the starting points of the same action between main and sub moving objects (step 2). When a time difference exists between the main and sub moving objects, a uniform velocity linear motion area of the sub moving object is searched to make a shift to an equation of adjustable speed motion between both the moving objects for the absorption of the time difference (step 3).
