Title: Small dc motor
Inventor: KOGA SHINYA
IPC: G11B15/30
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To provide cost reduction and a simplified process by reducing the number of parts to be used in the pulling-out stopper part of a rotating structure for a small DC motor. SOLUTION: This DC motor is formed as follows: A yoke 14 is integrally- provided in the lower surface of a lower spindle magnet 8 in the rotating structure of a motor and pierced by a through-hole 15. The attracting force caused by the leaking flux of the lower spindle magnet 8 passing through the through- hole 15 is made to work upon the base 1 of a magnetic member, thus retaining the rotating structure of the motor against the base 1 so as not to come off.

Title: Ferromagnetic fluid seal with long life
Inventor: KURUDEITSUPU RAJI
IPC: F16J15/43
Filed: 1989-08-25
Abstract: PURPOSE: To render a ferromagnetic fluid seal comparatively long-lived by setting a magnetic flux at a small value enough to replenish ferromagnetic fluid when ferromagnetic fluid within a reservoir moves to cause a first ferromagnetic fluid seal loses its function. CONSTITUTION: A magnetic shaft 3 passes through center holes 16 and 17 bored in a cover 2 and a bottom wall 18 of a housing 1, a magnet column 4 and a pole piece 5 are coaxially placed about the shaft 3, and a plurality of teeth 35 and 36 form two systems of seal stages 50 and 52, between which a ferrofluid reservoir 37 is situated. The magnetic fluxes of the magnet 4 are set at a small value enough to be strong for holding ferromagnetic fluid within the reservoir 37 stationary in it and to replenish ferromagnetic fluid within the first seal stage 50 when ferrofluid within the reservoir 37 flows to cause this seal stage 50 to lose its function. Resistance to high pressure difference in a relatively narrow seal and a long life can thereby be devised.

Abstract: PURPOSE:To smoothly perform attachment and replacement of an IC package with a small number of components by controlling a contact pin with a push- moving piece of a cover via a push-moved piece and releasing the engagement with a hooking piece by means of a releasing piece. CONSTITUTION:When a cover 11 is lowered, a push-moving piece 16 of the cover 11 enters a groove type moved piece 10c of a contact pin 10, and a contact piece 10d removes from a base 2 so that an IC package P can be easily installed on the base 2. When a hooking piece 8 of a socket body 1 is pressed under this condition with a releasing piece 9, the cover 11 locked with the hooking piece 8 is released and the cover 11 resiliently forced upward rises as far as the pin 10 comes into contact with the package P. When the cover 11 is further lowered, the connected condition is similarly released so that the replacement of the package P is easily performed. As a result, attachment and replacement of the IC package P is performed smoothly with a simple constitution of a small number of components.

IPC: H04N5/335
Filed: 1992-07-28
Abstract: PURPOSE:To fabricate a highly sensitive amplifying solid state image sensor having excellent spectral sensitivity characteristics wherein lowering of blue color sensitivity is restricted. CONSTITUTION:A poly-Si film 22 and a PSG film 26 are formed sequentially on a gate dielectric film i.e., an SiO2 film 21, and impurities are solid phase diffused from the PSG film 26 into the poly-Si film 22 through heat treatment. The PSG film 26 and the poly-Si film 22 are then machined-according to a gate electrode/translucent film pattern and ions of impurity 25 are implanted with the PSG film 26 as a mask thus forming diffusion layers 16, 17. Since channeling does not take place through solid phase diffusion of the impurities 23 and the PSG film 26 is used as a mask in the ion implantation of the impurities 25, the poly-Si film 22 can be made thin and the thickness of the SiO2 film 21 can be set independently from the poly-Si film 22.

Abstract: PURPOSE:To reduce air pressure sound generated due to compression waves, generated at the time of rushing into a tunnel, being emitted from a tunnel exit by making the body sectional area of head vehicles on both ends in a composed rolling stock smaller than that of intermediate vehicles. CONSTITUTION:The body height and body width of head vehicles 1a, 1b are made into smaller dimension compared to those of intermediate vehicles 2a-2n so as to be smaller in cross section. As a result, the compression wave at the entrance of a tunnel changes going through the process of two pressure rise stages of rising to the pressure corresponding to the body sectional area of the head vehicles 1a, 1b after forming the small pressure gradient theta1 of the compression wave surface by the inrush of the head vehicles 1a, 1b compared to the pressure gradient theta0 in the normal case and then rising to the pressure corresponding to the body sectional area of the intermediate vehicles 2a-2n. The maximum pressure gradient of the compression wave surface at the tunnel entrance at the time of inrush thereby becomes easy, and air pressure sound from a tunnel exit generated almost in proportion to the pressure gradient of the compression wave can be.
