Title: Ink jet recording apparatus
Inventor: TAKADA YOSHIHIRO
IPC: B41J2/21
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To lessen deterioration of a granularity of recording images due to bleeding of recording dots by sequentially recording ink drops on a recording medium from ink of a higher recording density and controlling an ink discharge amount for every discharge from each recording head. SOLUTION: At the time of recording images onto a recording medium by scanning a recording head unit 3 in an arrow A direction, recording heads 2 are arranged in an arrangement from a lower ink dye concentration to a higher ink dye concentration from the upstream to downstream of a scanning direction. Recording ink drops are recorded on the recording medium first from a recording ink of a high ink dye concentration. At this time, a set temperature of the recording head for light ink is set lower than a set temperature of the recording head for dark ink, whereby an ink discharge amount per dot from the recording head for light ink is made smaller than an ink discharge amount per dot from the recording head for dark ink.

Title: Heat transfer pipe for evaporation and condensation
Inventor: YOSHIDA TAKAYUKI
IPC: F28F1/12
Filed: 1987-02-02
Abstract: PURPOSE:To improve simultaneously the evaporation characteristic and condensation heat conductivity characteristic by one heat transfer pipe used for heat exchangers and make it possible to improve the mass productivity by forming a projecting section which has a void at least on one of the wall face in a pipe and wall face on the outside of the pipe and providing a mixture of the projecting sections and flat sections on the wall face. CONSTITUTION:A heat transfer pipe 10 has a projecting section 12 which is formed by a porous material layer which is provided on the inner wall face 11a of a circular pipe 11 in a lamination made by the adhesion of the sintering of a metal in the aluminium family or by the coating of a resin in flurorine family or metallic thin film or by other ways. A plurality of projection sections 12 are provided to form annular groups of them circumferentially with a distance P between axially adjoining groups of the pipe 11. Foaming is promoted from the positions where the projecting sections 12 consisting of the porous material layer of the heat transfer pipe 10 are formed, making the heat transfer characteristic of the heat transfer pipe 10 extremely good. The heat transfer characteristic at the spot where the projecting section 12 of the porous material layer is not formed is somewhat inferior, but it is not to a large extent. Further, the condensation heat conduction coefficient at the flat sections 15 of the inner wall face 11a on the heat transfer pipe 10 is improved because the condensation liquid film 14 between adjoining sections 12 is pulled to the projecting sections by their capillary action and it becomes thereby thinner.

Title: Gate valve
Inventor: MATSUDA SATOYUKI
IPC: F16K41/10
Filed: 1994-01-21
Abstract: PURPOSE:To restrain the occurrence of particles for use in a highly clean atmosphere by connecting a slide block to the base end of a stepped rod with a link so that the stepped rod can be oscillated via the link with the stepped rod coming near to or going apart from the slide block. CONSTITUTION:The opening of an opening 2 elongates an open/closed cylinder 27, as in opposite operation of the closing. In this way, the lowering of a slide block 28 is started and a spring 35 is first shortened to rotationally move a link 32 counterclockwise for separating a valve 11 from the valve seat of the opening 2. Furthermore, the elongation of the open/closed cylinder 27 lowers the valve 11 and opens the opening 2. In opening the opening 2, no slide occurs between the valve 11 and the valve seat of the opening 2 and no particles are induced. That results in a usable condition in a highly clean atmosphere.

Title: Electrophotographic method
Inventor: NAGAME HIROSHI
IPC: G03G21/00
Filed: 1993-01-13
Abstract: PURPOSE:To efficiently reduce residual potential caused by a DCL film, to attain electrical stabilization and to maintain stable excellent image quality for a long period by imparting the charge of a reverse polarity and executing the full surface exposure with light of wavelength in the vicinity of the maximum sensitivity, between cleaning and uniform electrification. CONSTITUTION:For reducing the residual potential, the charge of the polarity opposite to that of electrification by a uniform electrifier 11 is imparted by a reverse polarity charge imparting device 17 and then, the full surface exposure is executed by a full surface exposing device 18 (a). Or the electrification of the reverse polarity is imparted and simultaneously the full surface exposure is executed (b). Or after the full surface exposure is first executed, the electrification of the reverse polarity is attained (c). In these ways, there is a little difference in the effect. However, the effect is hardly obtained in the charge of the reverse polarity by itself or the full surface exposure by itself and the operations of both devices 17 and 18 are surely required. As a potential applied by the reverse polarity charge imparting device 17, 200-700V is desirable. It is desirable that the full surface exposing device 18 is by a light source having the wavelength in the vicinity of the maximum sensitivity possessed by a photosensitive body 10.

IPC: G11B15/665
Filed: 1990-02-02
Abstract: PURPOSE:To omit a stroke absorbing mechanism, to reduce the number of parts, and to simplify the constitution of a tape loading mechanism by applying the forward driving force to the tape loading member with the energizing force of an elastic member together with the backward driving force applied with a cam of a cam member. CONSTITUTION:In a tape loading state, the tape loading drive members 4A and 4B are driven forward with the energizing force of the elastic members 5A and 5B that energize both members 4A and 4B in accordance with the cam shape of a cam member 6. Thus the tape loading members 1A and 1B are moved forward and a tape is loaded. In a tape unloading state, the member 6 is actuated to turn backward the members 4A and 4B against the energizing force of the members 5A and 5B. Thus the members 1A and 1B are moved back and the tape is unloaded. As a result, no stroke absorbing mechanism is required and the number of parts can be reduced together with simplification of the constitution of a tape loading mechanism.
