Title: Vacuum container
Inventor: IKEDA MITSUAKI
IPC: H01J41/18
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To provide a vacuum container in which heating is evenly carried out, which is not deformed, and by which a clean and ultra high vacuum state is produced within a short time. SOLUTION: The inner surface on the vacuum side and the surface of the outside of this vacuum container 3 are made of anodic oxide coated aluminum or an aluminum alloy and a cathode to emit electrons by electric field emission by negative voltage application is installed in a fine pore existing in the anodic oxide coating 33 in the inner surface and a high voltage terminal 4 to apply high voltage to the cathode is installed in the vacuum container 3. Moreover, a metal coating with high reflectivity such as aluminum coating may be formed on the surface of the aprodic oxide coating 33 on the vacuum side. When high voltage is applied to the high voltage terminal 4, electrons are emitted out of the electric field emission material of the cathode in the fine pore and due to the electron emission, large electric current flows and the temperature of the vacuum container is rapidly increased due to the Joule heat and clean and ultra high vacuum state can be produced within a short time.

Title: Maintenance cap
Inventor: AKAO YUJI
IPC: B41J2/185
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To prevent an atmosphere communicating aperture and a suction aperture from using clogged and make it possible to use a perfectly water-proof pigment ink by providing a check valve in the atmosphere communicating aperture in a maintenance cap and a sealing valve in the suction aperture. SOLUTION: A check valve is provided on the upper part of an atmospheric communicating aperture 3 in such a way that the check valve covers the entire atmospheric communicating aperture. On the other hand, a maintenance cap 1, made of a rubber member, causes the check valve to be movable. Consequently, when the internal pressure of the maintenance cap 1 is negative, the check valve is opened to allow inflow of an atmosphere into the maintenance cap 1. When the atmosphere flows through the interior of the maintenance cap 1, an ink is not allowed into the atmosphere communicating aperture 3 resisting the flow of the atmosphere. In addition, when the atmosphere communicating aperture 3 is closed, or no negative pressure is present in the maintenance cap 1, the check valve is kept closed, so that the ink does not find its way into the atmosphere communicating aperture 3.  On the other hand, a sealing valve for simply sealing the suction aperture 5 to suppress ink evaporation is provided on the upper part of the suction aperture 5 in such a manner that the entire suction aperture 5 is covered.

Title: Injection molder
Inventor: EJIMA MITSUAKI
IPC: B29C45/62
Filed: 1985-03-12
Abstract: PURPOSE:To eliminate the variation in the supply of resin material into a cylinder and consequently prevent the ununiform supply of melt resin from occurring by a structure wherein a guide groove, which communicates with a resin material supply port, is provided in a cylinder so as to store resin material in the cylinder. CONSTITUTION:A resin material supply port 6, which is bored on the bracket 3 of a cylinder 1 and communicated with the lower end of a hopper 4, is communicated with a guide groove 7 bored on the cylinder 1. The rear end 7b of the guide groove 7, the front end 7a of which coincides with the front end of the supply port 6, is extended to the position nearly same as the position of the riser part 2a of a screw 2 in the retreated state. Accordingly, the resin material 5 (not shown) in the hopper 4 falls by gravity from the supply port 6 in the guide 7 when the screw 2 retreats and fills the riser part 2a of the stem of the screw 2 when the screw 2 advances. Consequently, when the screw 2 advances, the resin materials 5 in the riser part 2a is fed out, resulting in eliminating the condensation and rarefaction of the resin material 5 (not shown) and accordingly the resin is supplied uniformly.

Title: Control device of internal combustion engine
Inventor: YOSHIOKA MAMORU
IPC: F02D41/04
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To establish good drivability and to improve the a fuel consumption as well as emission by preventing a torque shock at the time of changing over the valve overlapping amount between a lean combusting control and stoichiometrically rich combustion control conducted by a variable valve timing device. SOLUTION: If the engine operation is in a lean combustion control condition (S 149 'Yes'), a valve overlapping amount is adjusted continuously (S150) on the basis of a map pattern for the lean combustion control, and if in a stoichiometrically rich combustion control condition (S140 'No'), the valve overlapping amount is adjusted continuously (S160) on the basis of a map pattern for the stoichiometrically rich combustion control. Therefore, a step difference at changing-over reduces, compared with in the case of control conducted with only two stages of valve overlapping amount, so that a torque shock can be prevented. Accordingly, good drivability can be established, and a fuel consumption as well as emission can be improved.

Title: Spacer rod for sz-type optical fiber cable, and optical fiber cable using it
Inventor: IWATA HIDEYUKI
IPC: G02B6/44
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To prevent the arrangement of optical fiber tapes from getting out of order, by forming grooves in such a way that the width in narrowed at reversing parts where a turning direction is reversed, and at a normal part positioned at the middle of two adjacent reversing parts. SOLUTION: The spacer rod 1 is provided with five grooves 2 with an equal space in the cirfcumferential direction, and four-core optical fiber tapes 3 are laminated and mounted in these grooves 2. The dimensions of the groove 2 differ depending on the lengthwise position of the rod 1. In this case, the depth (h) of the grove 2 is 2.0mm, for instance, in any position, but width (w) is changed periodically and continuously, and the grooves 3 are so formed that the width is narrowed at a normal part A. At the normal part A, the tapes 3 are laminated in good order to the grooves 2, so that the width of the grooves 2 are narrowed to 1.4mm, but the tapes 3 are accommodated with some allowance. A clearance between the tape 3 and the groove 2 is 0.1mm on one side and 0.2mm on both put together. Since the clearance is this small, there is not falling-in clearance for the tape 3 detached from the lamination. As a result, the arrangement of the tapes 3 is prevented from getting out of order.

Filed: 1994-03-18
Abstract: PURPOSE: To perform high-speed operation of a sense amplifier and to lower power consumption by forming a product term through the transistor cascode amplifier of the sense amplifier by the small group of sub-product terms. CONSTITUTION: Respective sub-product terms PTA and PTB form a product term through the transistor cascode amplifier 300 of this sense amplifier by switching transistors TRs 308 and 310. Then, when a node 350 is high, SAOUT becomes high, and when the SAOUT is high, the switching TR 308 and TR 310 are surely turned on. Then, when the switching TR 308 and TR 310 are on, the cascode 300 or 302 is turned on and the voltage of a PTA line and PTB line is lowered until it matches a current lowered by a TR 304 and a TR 306. Thus, the node 350 is pulled down to low. As a result, the high-speed operation of the sense amplifier 304 and the reduction in the power consumption are made possible.
