Title: Driving device for vari-focal lens
Inventor: TSURUKAWA IKUYA
IPC: G02B7/08
Filed: 1987-12-26
Abstract: PURPOSE:To reduce the diameter of a lens barrel frame, etc., by arranging an annular gear coaxially with an optical axis, and inhibiting the gear from cutting off effective luminous flux when moved from the position on the optical axis corresponding to the longest focal length to the position corresponding to the shortest focal length. CONSTITUTION:The diameter of the inner peripheral surface 51 of the annular gear 15 is so set that the effective luminous flux 50 entering a 3rd lens 2 in a wide state has the largest sectional are and is not vignetted. The direction wherein the annular gear 15 moves away from the incidence surface 52 of the 3rd lens 2 is the direction wherein the effective luminous flux becomes thin, so the effective luminous flux 50 is never vignetted by the annular gear from the wide state to the telephoto state. Consequently, the diameter of the inner peripheral surface 51 can be reduced and the whole device (lens barrel frame 4 and fixed frame 6) is reducible in size as compared with a case wherein the annular gear 15 is fitted to a fixed frame 1 which is an immobile member.

Title: Flash memory
Inventor: KAWAMURA SHOICHI
IPC: G11C16/02
Filed: 1993-12-27
Abstract: PURPOSE:To obtain a constant erasing characteristic by controlling a current flowing through a source of a memory cell transistor so as to become a prescribed current value, and eliminating dependency of the erasing characteristic on erasing voltage supplied from the outside and thickness of a film between a substrate and a floating gate. CONSTITUTION:When a current value of a current Is flowing through a source of a memory cell transistor(Tr) becomes larger than the reference current Iref, a current IA flowing through a pMOSTr 19 and a nMOSTr 23 becomes larger than a current value of the Iref. Consequently, a current value of a current IB flowing through a nMOSTr 22 becomes larger than a current value of the Iref, voltage of a node 24 is dropped, gate voltage of a nMOSTr 15 is dropped. Therefore, as the Is is decreased, voltage of the node 24 is recovered to a normal value by the Iref, the Is is made equal to Iref. On the other hand, when the Is becomes smaller than Iref, the IA also becomes smaller than the Iref. Consequently, the Is also becomes smaller than the Iref, voltage of the node 24 is boosted and gate voltage of the Tr 15 is boosted. Therefore, as Is is increase, voltage of the node 24 is recovered to a normal value by the Iref, and the Is is made equal the Iref.

Title: Plastics fusion-bonding device
Inventor: YAMAZAKI MASAMI
IPC: B29C35/08
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To accurately form an image on a focusing plane with an infrared radiation and thereby apply a thermal energy at high efficiency by providing an infrared radiating device equipped with a halogen lamp for irradiation with infrared rays having a plate-like filament whose spread is orthogonal with an axial line connecting a reflector with a fusion-bonded area. SOLUTION: The spread of a filament F1 on a halogen lamp 11 in an infrared radiating device 1 is orthogonal with an axial line connecting a reflector 12 with a fusion-bonded area. Consequently, an infrared radiation from the filament F1 is focused to a desired fusion-bonding position while the radiation is reflected by the reflector 12, and a formed image F2 is of the same shape as the face of the filament F1. In addition, the formed image F2 is parallel with a desired fusion-bonding face, so that the infrared rays are almost entirely not radiated to the outside of the formed image. Thus it is possible to minimize the wasteful consumption of an energy from the halogen lamp 11 and realize the heating at high efficiency.

Title: Game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 1993-11-30
Abstract: PURPOSE:To provide a game machine in which an image displayed on an image display device can give a larger decorative effect to a game player. CONSTITUTION:A lenticular plate 54 capable of displaying an image displayed on a liquid crystal panel 55 stereoscopically is disposed in front of the liquid crystal panel 55. When the same tone data is sent to display elements adjacent to each other among display elements of the liquid crystal panel 55, binocular parallax is gone so that an image can be seen in a plate even if passed through the lenticular plate 54. On the contrary, when different tone data are sent to display elements adjacent to each other, binocular parallax becomes larger so that an image can be seen stereoscopically through the lenticular plate 54. Thus, an image displayed on the liquid crystal panel 55 can be seen in a plane or seen stereoscopically by controlling the tone data of the image according to the game condition so that larger decorative effect can be given to a game player and the game player's interest can be increased.

Title: Surface acoustic wave oscillation circuit
Inventor: YOSHIZAWA KAGEHARU
IPC: H03B5/30
Filed: 1989-12-20
Abstract: PURPOSE:To expand the variable range of an oscillating frequency by providing a resistor connecting in parallel with a surface acoustic wave resonator. CONSTITUTION:A resistor 21 is added in parallel with a surface acoustic wave resonator 55. Thus, the resonance sharpness of the resonator 55 is reduced and the rate of change in a resonance frequency of the resonator 55 with respect to a change in the static capacitance of a varactor diode 53 is expanded. That is, since a change in the capacitance of a varactor diode 53 with respect to a change in a control voltage VF is constant, the rate of change in the resonance frequency of the resonator 55 with respect to the change in the control voltage VF is expanded. Thus, the variable range in the oscillating frequency within the variable range of a prescribed control voltage is expanded.
