Title: Ink jet printer
Inventor: KYO KAZUNORI
IPC: B41J2/175
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To suppress generation of bubbles in an ink jet head by providing means for heating ink to a set temperature in an ink tank for supplying ink to the ink jet head thereby reducing air dissolved into the ink. SOLUTION: When ink in an ink tank 1 is heated by a heating means 5, a large volume of dissolved air is discharged into the space above the tank 1 from the ink heated up to high temperature. Consequently, ink from which dissolved air is reduced is fed through an ink tube 6 to an ink head 12. During that process, temperature is lowered trough natural cooling and air can be dissolved but since ink passes through the ink tube 6 without touching the air, air is not dissolved additionally. When the ink passes through the head 12, temperature rises less than temperature drop and a small volume of dissolved air is discharged but since air dissolving margin incident to temperature drop is slightly higher, air is not separated and generation of bubbles is suppressed.

IPC: A63F7/02
Filed: 1991-04-17
Abstract: PURPOSE:To efficiently manage the pinball by stopping the return of a premium ball to a pinball island in order to change freely the pinball holding quantity to an arbitrary quantity. CONSTITUTION:An arithmetic means 75 derives the difference number of balls between the total number of balls of the number of going-in balls by a going-in ball detector 71 of each pinball machine 21 plus the number of collected balls by a ball counting machine 51 and the number of going-out balls by a going-out ball detector 72 plus the number of leading balls by a ball lending machine 22.

Title: Semiconductor memory device
Inventor: SUZUKI TORU
IPC: G11C11/34
Filed: 1987-04-06
Abstract: PURPOSE:To improve the noise-resisting property by providing mimic bit line sense amplifiers in the ends of a bit line sense amplifier group. CONSTITUTION:A pair of mimic bit line sense amplifiers 3A and 3B are added in both ends of a group of bit line sense amplifiers 1A-1D. An influence of coupling noise and the other noise upon bit lines BL1 and the inverse of BL4 in both ends is greater than that upon the other bit lines, of which the coupling capacities exist on both sides, because coupling capacities exist only one side of bit lines BL1 and the inverse of BL4. Since mimic sense amplifiers 3A and 3B are provided, the noise resisting property of these bit lines BL1 and the inverse of BL4 is equal to that of the other bit lines because coupling capacities exist on both sides of bit lines BL1 and the inverse of BL4 in both ends. Since these lines are not ends physically, the noise from a peripheral circuit is reduced, as well.

Filed: 1995-04-11
Abstract: PURPOSE: To connect any arbitrary resource in each system by preventing an external DGU resource from being redundantly constituted in an information processing system provided with plural systems of CPU and DGU with a redundant constitution and the external DGU resource connected to these plural systems of DGU. CONSTITUTION: ID information is applied for each external DGU resource 9, and the ID of the resource 9 connected to a present system is previously set by a resource ID part. In response to a transaction from any CPU, it is detected by a resource access discrimination part 6 whether the access address of this transaction is matched with this set ID or not and only when they are matched, the relevant access is sent through an execution part 7 to the external resource 9 to control the execution. At the other non-coincident system, a standby state is provided during this processing and when read data are sent from the resource 9 under executing as a response, the execution part 7 sends these read data from a port part 8 to the other system DGU as well. All the DGU respectively send these read data to the CPU of their own systems at the same time.

Title: No-break power unit
Inventor: MORIKAWA TETSUO
IPC: H01L23/36
Filed: 1984-04-28
Abstract: PURPOSE:To obtain a compact device at a low cost, by performing the cooling of a semiconductor rectifying element and the cooling of a semiconductor switching element by a common cooler, and using only one cooling device. CONSTITUTION:A thyristor rectifier 1 and a thyristor 7 of commercial power supply are commonly attached to a block 13. A load current flows to the thyristor rectifier 1 at a normal time, and a current does not flow through the thyristor 7. Meanwhile, when a no-break power unit fails, the load current is supplied from the thyristor 7, and the current does not flow to the thyristor rectifier 1. Therefore, the cooling capability of a cooler is designed so that the capability corresponds to the element having the larger amount of heat generation either in the thyristor rectifier 1 or the thyristor 7. The thyristor rectifier 1 and the thyristor 7 are attached to the same attaching block 13. A heat pipe 14 and cooling fins 15 are commonly used. Thus the compact device can be obtained at a low cost.

Title: Rolling mill line
Inventor: IWANAGA TAKESHI
IPC: B21B1/38
Filed: 1980-06-24
Abstract: PURPOSE: To reduce the hardness dispersion in the direction of thickness of a rolled material, by installing a light reducing rolling mill between a hot rolling mill and a cooling apparatus, in a rolling mill line operated for improving the tenacity of steel through a forcible cooling process following to a rolling pass.  
     CONSTITUTION: A steel billet extracted from a soaking pit is rolled to reduce its thickness by a hot rolling mill 1, and is carried into a cooling apparatus 2 through a leveler 3. A light reducing rolling mill 4, provided with a rolling roll of diameter smaller than that of the main rolling mill 1, is installed in front of the leveler 3. This rolling mill 4 gives a great strain to only the steel surface before entering the cooling apparatus, in order to promote the γ→α transformation by the distortion stress and by fining grains, for preventing generation of such a hardened structure as martensite in the steel surface during the next forcible cooling process. If the said light reducing mill 4 is installed next to the leveler 3, it is more effective because the rolling strain is released and the recrystallization and grain growth are restricted thereby.

Title: Electric current follower circuit
Inventor: HARUYAMA KIYUUICHI
IPC: H03K17/00
Filed: 1979-07-05
Abstract: PURPOSE: To realize an ideal electric current follower circuit by the simple circuit method of FET and an inverting circuit suitable for a monolithic integrated circuit.  
     CONSTITUTION: To input terminal 17 of the electric current follower circuit, electric current source 1 is connected. Now, in case that output terminal 16 gas voltage amplitude, the gate-source voltage of FETQ13 varies, but appears as a variation in gate potential and the source of FETQ13, i.e. input terminal 17 has only a variation obtained by dividing the above-mentioned voltage variation nearly by the gain of inverter 10. Since an inverter with a gain ≥10 times can easily be realized by the ordinary integrated-circuit technique, the voltage variation at output terminal 2 of electric current source 1 is further reduced by ≥1 digit, and consequently the remarkable improvement of output impedance can be attained.
