Title: Lc oscillation circuit and proximity sensor using the same
Inventor: TANIGUCHI MICHIAKI
IPC: H03B5/08
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To precisely change oscillation frequencies without changing the reactance of an oscillation circuit by changing the loop gain of the feedback loop of an amplifier circuit without changing the resonance frequencies of an LC self-excited oscillation circuit. SOLUTION: An LC self-excited oscillation circuit 1 is a self-excited oscillation circuit including a coil and a capacitor, and one part of AC signal is detected by a signal detecting means 2, and applied to an amplifying element 3. The amplifying element 3 amplifies the input signal, and allows it to positively feedback through a feedback circuit 4 to an LC self-excited oscillation circuit 1. Then, the DC bias point and operating point of the amplifying element 3 are decided by a DC bias circuit 5.  Thus, oscillation frequencies can be changed by changing the operating point of the amplifying element 3 by the DC bias circuit 5 or the resistance value of the feedback resistance of the feedback circuit 4, and changing the amplification factor of the amplifying element 3 by leaving resonance frequencies as they are without changing the value of the inductance or capacitor of a self-excited oscillation circuit 1.

Title: Focal distance switching camera
Inventor: OMIYA AKIO
IPC: G03B17/12
Filed: 1987-12-25
Abstract: PURPOSE:To prevent a focal distance from being continuously and periodically switched by completing the switching of focal distance every switching with one reciprocation of a 2nd interlocking member. CONSTITUTION:The 2nd interlocking member 27 which is made to interlock with a 1st interlocking member 11 through a locking member 26 is restored to an initial state, accompanied with the release of locking of the locking member 26, with the aid of an energizing means. Even if a focal distance switching knob is kept on a switching side and the 1st interlocking member 11 is positioned on the switching side by interlocking with that, the 2nd interlocking member 27 performs one reciprocating displacement so that the switching of focal distance is performed with a focal distance switching start signal with the one reciprocating displacement. Thus, the focal distance is prevented from being continuously and periodically switched even if the focal distance switching knob 46 is kept in the switching side.

Title: Color identifying mechanism of cathode-ray tube
Inventor: TSUNEKAWA MINORU
IPC: H01J29/07
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To restrain damper floating with a simple structure and prevent disturbance of landing to a fluorescent face of an electron beam and image disturbance by permitting a dummy support tape formed outwardly and transversely of a support tape to absorb excessive tensile stress of a damper wire by an error at a mounting position of a damper spring. SOLUTION: When excessive tensile stress is generated at a damper wire 12, an excessive load is applied to an end of a FAG(Flat Aperture Grill) 10, however, this color identifying mechanism 4 is intended to absorb such excessive load applied to the end of FAG10 by a dummy support tape formed outside of the support tape 16. That is, when an excessive tensile stress is generated at the damper wire 12, a rotational moment is produced at a dummy support tape 17, and the dummy support tape 17 is displaced. Thus, by displacing the dummy support tape 17, excessive tensile stress of the damper wire 12 is offset.

Title: Silicon carbide semiconductor device
Inventor: TAKEUCHI YUICHI
IPC: H01L29/12
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To prevent a gate insulating film from being broken down and to prevent the life of the gate insulating film from becoming short. SOLUTION: A source region 5 is formed having regions 5a and 5b and the reverse surface of the region 5b is positioned below the reverse surface of the region 5a. A longitudinal power MOSFET has a groove 6 formed not at right angles to the surface of a semiconductor substrate 4, but obliquely to some extent. Consequently, a depletion layer becomes bent, but a punch- through phenomenon takes place at the part of the region 5b because of the region 5b having the underside surface below the underside surface of the region 5a. Therefore, no punch-through phenomenon takes place on the interface between the region 5a and gate oxide film 7, i.e., SiO2 /SiC interface. Consequently, the gate oxide film 7 is prevented from being broken down, and the life of the gate insulating film 7 is prevented from becoming short.

IPC: B29C67/00
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To simply shape an object three-dimensionally with high dimensional precision and high productivity by bringing the lower face of a light-transmitting film into contact with the liquid face of a photocurable resin liquid and pressing the resin liquid to be flattened, and then forming a cured resin layer with a specified pattern and a specified thickness through the emission of light from above and further, peeling the film to again form a photocurable resin liquid layer with a specified thickness on the curable resin layer. SOLUTION: The entire curable resin layer L1 on the liquid level 2' of a photocurable resin liquid 2 in a shaping bath 1 is covered with a continuous long light-transmitting film 4 using supply rollers 5a, 5b and take-up rollers 6a, 6b. The lower face of the film 4 is brought into contact with the liquid level 2', which is, in turn, pressed using a light-transmitting pressing plate 8 to be flattened. Further, light is emitted to the resin liquid 2 from a light source 9 above so that the resin liquid 2 is photocured to the specified pattern and thickness and a cured resin layer L2 is formed on the lower face of the film 4. In addition, a pressing plate 8 is sidetracked to gradually peel the film 4 from the cured resin layer L2 and a table 3 on which the cured resin laminates L2/L1 are placed is lowered to repeat the process.  Thus it is possible to manufacture an optical three-dimensionally shaped object with a flat surface and a high dimensional precision rapidly, efficiently and smoothly.
