Title: Lens driving device
Inventor: EMURA TETSUJI
IPC: G02B7/08
Filed: 1988-07-08
Abstract: PURPOSE:To accurately convert the angle of rotation of an electric motor into the movement quantity of a rear component lens in the optical axis direction by providing a gap adjusting member fixed to a driving shaft and spacers interposed between the gap adjusting member and a bearing. CONSTITUTION:The cylindrical gap adjusting member 9 is fixed on the driving shaft 7a extended from a rotor 7f closely to the bearing 7e. The spacers 10 which are thick enough not to disturb the rotary motion of the rotor 7f are interposed in the gap between the gap adjusting member 9 and bearing 7e. Thus, the gap adjusting member 9 and spacers 10 are added to hold the rotor 7f and driving shaft 7a of a pulse motor so that there is no mechanical play in their lengthwise direction. Consequently, the angle of rotation of the electric motor 7 can accurately be converted into the movement quantity of the rear component lens 1C in the direction of the lens optical axis alpha.

Title: Automatic metering device
Inventor: YOSHIHARA TAKAO
IPC: H04Q9/00
Filed: 1990-06-25
Abstract: PURPOSE:To call various kinds of data of each user at any time even when a centralized control device or a transmission line has a trouble or an accident by transmitting a storage command signal to a data control means at a specified time, and storing data of a first storage means in a second storage means. CONSTITUTION:In a terminal equipment 3, when a meter inspecting command signal is not received within the specified time, a timer 15 transmits the storage command signal. A control circuit 9 which receives the storage command signal stores the data of a counter 10 at that time in a data memory 14.

Title: Coating method with aerosol
Inventor: MATSUNAGA MASABUMI
IPC: B05D1/02
Filed: 1990-06-29
Abstract: PURPOSE:To increase coating efficiency by heating an aerosol to a temp. above the temp. of a body to be coated during generation and/or transfer, condensing vapor of a solvent present in an atmosphere with particles of the aerosol in the atmosphere as nuclei, further condensing the vapor on the surface of the body to be coated and sticking the particles of the aerosol and the solvent on the body to be coated. CONSTITUTION:A soln. L to be sprayed to increase the amt. of vapor or a carrier gas CG and/or an aerosol generator 1 is heated or a generated aerosol is further heated during transfer. A body Oa to be coated is set at the lower part of a coating booth. Since vapor of a solvent in the aerosol is in a satd. state at a temp. above the temp. of the body Oa, the vapor is condensed by the temp. difference with particles of the aerosol as nuclei and further condensed on the surface of the body Oa. Fine particles R carried by the carrier gas collide against drops formed by the condensation, the kinetic energy of the particles is absorbed in the drops to reduce the bound of the particles and the particles stick on the drops. When a large number of such drops gather, a liq. film Sf is formed, covers the entire surface of the body Oa and can further reduce the bound of the fine particles.

Filed: 1990-06-29
Abstract: PURPOSE:To prevent the occurrence of density irregularities and wrinkle by a method wherein a peeling claw formed into a V shape at a part abutting on ink paper is provided so as to extend in the width direction of the ink paper, and an ink guide changing an ink paper path is disposed upstream of an ink take-up roll of an ink cassette and downstream of the peeling claw. CONSTITUTION:After recording, an ink film 3 is peeled from recording paper 17 by a peeling claw 9 and a release guide 10. The peeling claw 9 and the release guide 10 realize a release angle 15 of 90 degrees or more. The release angle 15 can be constantly stable by the control of the rotation torque of an ink take-up roll 4 and the action of an upper roller 16. In addition, by mounting the release guide 10 on an ink cassette 5, the release guide 10 can come closer to a thermal head 7, and the release angle 15 of 90 degrees or more can be set. A friction board 32 and a spring 33 apply a force of inhibiting the rotation of an ink supply roll to the ink supply roll, which produces a tension in an ink film 3 under the thermal head 7. An ink guide with cover 13 prevents the ink film 3 from producing a wrinkle.
