Patent JP-H0528891-A (JP)
Title: Relay circuit
Inventor: KANEMICHI HIDEO
IPC: H01H47/22
Filed: 1991-07-22
Abstract: PURPOSE:To perfectly prevent flow of a rash current in a main relay and also an arc discharge by connecting a bypass minor current circuit due to an aux. relay in parallel connection with the main relay before the main relay when the power is put on, and disconnecting after the same when the power is put off. CONSTITUTION:To put on the power for a load 15, an aux. relay 12 constructed smaller than a main relay 11 is actuated at a speed 10 times as quick or more when On pulse is impressed on drive coils 11c, 12c of the two relays 11, 12. Therefore, relays 12a, 12b are actuated earlier, and a preliminary current flows in the load 15, and the main relay 11 is actuated retardantly. Therein no rash current is generated because preliminary current is already flowing, but the rated current should flow. To put off the power to the load 15, on the other hand, Off pulse is impressed on a drive coil 11d of main relay 11. When first the contacts 11a, 11b are opened, other contacts 12a, 12b are opened by the partial pressure output, and a resistance 17 is inserted in parallel with the contacts 11a, 11b of the main relay by the aux. relay 12 so as to prevent generation of a counter-electromotive force.

Title: Semiconductor device
Inventor: TSUNODA TETSUJIRO
IPC: H01L29/749
Filed: 1994-08-02
Abstract: PURPOSE:To eliminate the decrease in a breakdown strength of a current detecting cell and obtain the same current detection output even if the carrier life times are different by locating the current detecting cell between main current-side unit cells. CONSTITUTION:A current detecting cell 31 is located between main current-side unit cells 32 or surrounded by them on four sides. Due to this structure, the creeping of holes from under bonding pad sections of the main current-side unit cells which are very much larger than the current detecting cell 31 is prevented and hole current is allowed to flow uniformly in both the current detecting cells and the main current-side unit cells. Therefore, the latchup current density of the current detecting cell 31 and that of the main current-side unit cells 32 are the same and precise current detection is possible. At the same time, the current detecting cell is not broken down by, what is called, the commutation dv/dt.

Title: Office constructing equipment
Inventor: ODA SHIGENOBU
IPC: E04F15/024
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To reduce a cost caused by a change in layout by prearranging wiring taking out ports in a floor in response to a virtual grid having a pitch of plural times an arranging pitch of unit floor materials. SOLUTION: Office constructing equipment is provided with a floor F forming a wiring space S on the under surface side by arranging unit floor materials 1 in a plurality and plural wiring taking-out ports 2 arranged in the boundary part of the adjacent unit floor materials 1 so that the wiring taking-out ports 2 are prearranged on the floor F in response to a virtual grid G having a pitch PP of ten times an arranging pitch P of the unit floor materials 1.  Thus, since the wiring taking-out ports 2 comparatively uniformly and separately exist on the floor F along the virtual grid G, if only underfloor wiring L being a basis capable of passing through the predetermined wiring taking-out ports 2 is applied, even if a wiring required place is changed, wiring C and the like can be led out from the nearest wiring taking-out port 2, so that layout work changing work can be efficiently performed. Thus, a maintenance cost can be reduced.

Title: Fixed volume discharging device
Inventor: HIRAMATSU TORU
IPC: B05C11/10
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To improve productivity by shortening the fall time of the pressure in a syringe after discharging the fixed volume of liquid from this syringe. SOLUTION: Pressurized air is supplied via a solenoid-operated selector valve 6 from an air supplying source 8 to the syringe 2 packed with the liquid 1 and the fixed volume of the liquid is discharged from the syringe 2. A quick exhaust valve 4 is arranged near the syringe 2. This quick exhaust valve 4 is operated by the pressurized air in the syringe 2 to discharge the pressurized air in the syringe 2 at the ending time of the supply of the pressurized air. The route for discharging the pressurized air from the syringe 2 is made shorter than heretofore, by which the resistance of the discharge is lowered and the fall time is shortened. In addition, the pressure in the syringe 2 is instantaneously released at the end of the discharge and, therefore, the liquid droop from the syringe 2 by the residual pressure is prevented.

Filed: 1990-07-09
Abstract: PURPOSE:To avoid the mixing of nitride into the aluminum layer while a film-forming operation is conducted by a method wherein a vacuum heating process, in which nitride is degassed from a high melting point metal nitride layer, is provided between the aluminum layer forming process and the high melting point metal nitride layer forming process. CONSTITUTION:An impurity-diffused silicon layer (diffusion layer) 2 is formed on a silicon substrate 1 which will be used as a base, a PSG insulating layer 3 of 1mum in thickness is formed thereon by a CVD method, and a contact hole 4 of 1.5mum square is made in the above-mentioned layers. After the surface of a titanium nitride layer 6 has been scraped off by 100Angstrom  thereabout by conducting RF etching (high frequency etching process), nitrogen 7 is degassed from the titanium nitride layer 6 by conducting a heat treatment (vacuum heating process) at 400 deg.C for 180 seconds in vacuum. Then, an aluminum layer 8 of 9.5mum in thickness is formed on the titanium nitride layer 6 using a sputtering method. The substrate 1 is prevented from exposing to the air during the period of performance ranging from a high frequency etching process to an aluminum layer 8 forming process. This can be accomplished by coupling by a load lock having an automatic conveying mechanism between the devices with which each process is conducted.

Abstract: PURPOSE:To carry out the stabilized operation of a good crushing efficiency by controlling and maintaining only rods of one kind diameter by replacing worn small diameter rods with large diameter rods in a rod replacement method for a rod mill for using the large diameter rods and the small diameter rods and crushing a lumpy raw material. CONSTITUTION:In the rod replacement method for a rod mill for crushing a lumpy raw material by using large diameter rods and small diameter rods, for instance, in the case of crushing cokes by using large diameter rods of 90mm initial diameter and small diameter rods of 65mm initial diameter, the wear amount of the large diameter rods and that of the small diameter rods following the operation of a rod mill main body 1 is almost the same. For that reason, for instance, when the large diameter rod of 90mm initial diameter are worn to the 65mm diameter, the small rods of 65mm initial diameter are worn to the 40mm diameter. At that time, the small diameter rods of 40mm diameter are taken out, and the large diameter rods of 90mm initial diameter of the same number are inserted. In other words, the large diameter rods of 90mm diameter only are replenished.
