IPC: G11B25/04
Filed: 1988-01-19
Abstract: PURPOSE:To make a camera body compact by arranging a magnetic head feeding mechanism on the front side of a magnetic disk driving motor and arranging a magnetic head lifting mechanism on the opposite side of the motor. CONSTITUTION:In the head feeding mechanism, a plunger 20 is excited at the time of ending the photographing of one sheet and the position of a cam groove 23b formed on a latchet gear 23 is changed, so that a head board 24 is moved along a guide 27 only by a fixed distance. Thus, the teeth of the latchet gear 23 are sent one by one every photographing operation and a magnetic head is moved in each track. After exciting a plunger 10 synchronously with the photographing operation of the camera, an iron core 10a of the head lifting mechanism is drawn, the magnetic head 7 fixed on the head board 24 is descended and abutted upon the magnetic disk stored in itself from an aperture 1a of an already loaded magnetic disk jacket 1. Thereby image information can be recorded in the magnetic disk. Thus, the whole electronic still camera can be made compact.

Filed: 1978-01-25
Abstract: PURPOSE:To suppress a large gate current in a triac by providing a groove between a region where a gate electrode is provided and that where a main electrode is provided and by strangulating current flowing to those regions. CONSTITUTION:On N-type Si substrate 10 constituting a thyristor, P-type base layer 11 and layer 11' touching it are diffusion-formed, where N-type gate region 12 and N-type emitter region 13 are both diffusion-formed.

IPC: H02K19/16
Filed: 1986-01-20
Abstract: PURPOSE:To reduce the holding torque effectively by providing a mechanism in which the magnetic repulsive force is generated opposing to the action of the magnetic attractive force between a stator section and a rotor section. CONSTITUTION:When a rotor 24 rotates clockwise, the one end of a pole piece 30 of the rotor 24 is situated right under an S pole field core, while the other end of a pole piece 30 is situated right under an N pole field core 20b. At this moment, the rotor 24 receives the magnetic attractive action through the magnetic piece 30. In the same phase as with the magnetic piece 30, a pole piece 32 faces N pole field cores 28b and 28b'. At this moment, as the pole piece 32 receives the action of flux from N poles of field cores 28b and 28b', the repulsive action is given to the rotor 24. Consequently, suppose the current of the field winding of the third static pole 28 is controlled so as to balance the magnetic attractive action and the magnetic repulsive action, the holding torque of the rotor 24 can be decreased.

Title: Synthesis of methanol from co under normal temperature and pressure using everitt's salt
Inventor: OGURA KOUTAROU
IPC: C25B3/25
Filed: 1984-01-19
Abstract: PURPOSE:To produce methanol from carbon monoxide, economically and selectively, by using Everitt's salt in combination with a catalyst comprising methanol and a pentacyanoferric acid salt under normal temperature and pressure. CONSTITUTION:CO is converted to methanol under normal temperature and pressure in an aqueous solution on the surface of platinum coated with Everitt's salt of formula K2FeIIFeII(CN)6, in the presence of a catalyst comprising methanol and the pentacyanoferric acid salt of formula Na3[Fe(CN)5]. The process is energy-saving because CO can be converted to methanol under mild condition of normal temperature and pressure. CO gas accompanied by the exhaust gas of the gasification of heavy oil or combustion of coal is used as a raw material in the present process, resulting in the higher utilization of petroleum and the effective utilization of CO in waste gas. The yield of metanol can be increased by applying small electrical potential through external circuit, and reducing the Prussian blue of formula KFeII(CN)6 produced by the reaction to Everitt's salt.
