IPC: G03G15/20
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To thermally cut a heat generating source off from space in a machine, in a state where loss in energy is small and to prevent the rising of temp. in the machine by providing a heating roll and a pressure roll, so as to enable contact/uncontact and a specific heating roll cover. SOLUTION: When the shaft 16 of the heating roll 11 is pushed down in a direction shown by an arrow E, together with the heating roll cover 19, the wing parts 23a and 23b of the cover 19 are abutted on stoppers 29a and 29b and the halves 19a and 19b of the cover 19 receive forces in directions shown by arrows F and G respectively. At this time, solenoids 33a and 33b are energized, plungers are in drawn-in states in the directions of arrows H and I against the forces of tension springs 34a and 34b and the top ends of arms 32a and 32b are abutted on the edge parts of flat parts 21a and 21b. Thus, even if the heating roll 11 is in a press-contact state with the pressure roll 12, most of the roll 11 is surrounded by the cover 19, so that radiant heat leaking from the roll 11 to the inside of the machine can be reduced.

Title: Ink jet recording head
Inventor: MATSUMOTO HIROZO
IPC: B41J2/165
Filed: 1992-11-02
Abstract: PURPOSE:To reduce the size and improve the durability of an ink jet recording head by providing a capping unit for detachably mounting an ink discharge port with an ink absorbing member therein to suck to clean the port and preventing drying of ink, and forming the absorbing member of inorganic porous material. CONSTITUTION:The ink jet recording head comprises a capping unit (a) for detachably mounting an ink discharge port with an ink absorbing member therein to suck to clean the port and preventing drying of ink. The absorbing member is formed of inorganic porous material 50 (e.g. porous Ni-felt), and inserted into a deep hole 7 in the unit (a). That is, since the absorbing member is formed of the porous material, ink permeability and retention amount are increased to decrease in size the capping unit. Further, since the absorbing member is formed of inorganic material, corrosion resistance to the ink is increased to improve its durability.

Title: Three value drive circuit
Inventor: OKAYASU TOSHIYUKI
IPC: G01R31/3183
Filed: 1990-11-22
Abstract: PURPOSE:To eliminate jitter generated by the charging voltage of floating capacity by giving charging current from a diode switch to be floating capacity being parasitic on from an activated switch control circuit to other switch control circuit and a switching circuit. CONSTITUTION:Diode switches D1 to D6 give charging current from an activated switch control circuit to the floating capacity being parasitic on the connection point between three switch circuits 4, 5 and 6 and the said switching circuit consisting of switch elements Q1 to Q6. Therefore, even with the relation between VT and VL to be VT<VL, by outputting voltage VL at the output terminal after outputting voltage VT at the output terminal, this voltage VL can be charged to the floating capacity being parasitic on the other switching circuits 4, 5 and 6. Thus, in the start up motion from voltage VL to VH, the charging is executed from the initial voltage of VL so that the output voltage VH can start up in normal time. By this, the generation of jitter is eliminated.

Title: Semiconductor memory
Inventor: NISHIHARA TOSHIYUKI
IPC: H01L21/8244
Filed: 1988-12-19
Abstract: PURPOSE:To cause a relatively large ON current to flow when pull-up is performed and make an OFF current small and then, stable by making load act as variable resistance elements which are controlled by gates of drive transistors. CONSTITUTION:Load is made up by channels of drive transistors Q1 and Q2 as well as variable resistance elements VR1 and VR2 having an opposite conductivity type low concentrated semiconductor parts which are controlled by gates of the drive transistors Q1 and Q2. The variable resistance elements VR1 and VR2 making up load have parts which are controlled by the gates Of the drive MOS transistors Q1 and Q2 and have the same conductivity type as those of the channels of the drive MOS transistors Q1 and Q2. As the above parts consist of a low concentrated semiconductor, a depletion layer is formed at the above parts by gate voltage when the drive MOS transistors Q1 and Q2 are ON. Consequently, the variable resistance elements VR1 and VR2 come to a large value which is almost determined by the resistance of the channels. In this way, when pull-up is performed, its resistance element causes a relatively large ON current to flow and makes an OFF current small and its value stable without making the ON current small.

Abstract: PROBLEM TO BE SOLVED: To reduce the heights of a refrigerant cooler and a refrigerant sprayer and cut down costs by a method wherein the refrigerant sprayer includes a partition plate that is almost horizontally arranged at a position under a joint part of a refrigerant supply pipe and above the planed liquid refrigerant level. SOLUTION: A partition plate 3 is horizontally arranged between a sidewall 1 on which a liquid refrigerant pipe is connected and an opposite sidewall 5 and is in contact with both sidewalls 1 and 5. Liquid refrigerant led to a refrigerant sprayer through the refrigerant pipe evaporates by itself on the partition plate 3. However, the refrigerant that scatters during spraying falls down after striking against an upper lid 2, and the sidewalls 1 and 5 or directly falls down, gathers once on the partition plate 3 and then steadily flows down from the partition plate 3 via an edge 3a. Thereby, an evaporator can be low in height and simple in constitution, resulting in a reduction in costs.
