Title: Mist removing device
Inventor: TANIGAWA YASUO
IPC: B01D45/16
Filed: 1980-03-18
Abstract: PURPOSE: To efficiently and easily collect minute liquid mist produced from the plating liquid, by giving a circular motion to the waste gas with the spiral projection installed at the inner wall of exhaust duct.  
     CONSTITUTION: When the plating liquid is condensed while the mist contained in the waste gas is being removed, the air which has become highly humid by taking moisture from plating liquid 2, is sent to mist removing device 9 through exhaust duct 8. Since spiral projection 10 is continuously installed at the inner wall of duct of this mist removing device 9, a circular motion is given to the air supplied from atmospheric air condenser 6 and the mist contained in the air is stuck to the wall. The stuck mist comes up along projection 10 together with the ascending air and does not flow out. The mist grown at the wall is collected by receiving tank 11 and taken out through outlet 12. With such mechanism, the mist removing capacity is not lowered even when the device is continuoulsy operated for a long time.

Title: Copying welding device
Inventor: IHARA YASUSHI
IPC: B23K9/127
Filed: 1981-03-10
Abstract: PURPOSE:To make a controller simple and make the attitude of a torch with respect to a weld line constant by supporting the torch on a carriage with a steering mechanism which is run for the purpose of performing fillet welding, by means of specific moving and members with roller connected with a detector. CONSTITUTION:A carriage 1 is placed on the work W by aligning its front and rear to approximately a horizontal fillet weld line WL direction. A moving member 4 is brought into abutment on the side face of the work via both rollers 9 by means of the spring in a projecting position detector (differential transformer) 5. The weld point position of a torch T is automatically aligned to the line WL by the rollers 9, 10. Thereupon, when a controller 12 is turned on, the carriage 1 advances at a constant speed to carry out welding. At this time, an electric motor M is so controlled that the projeting position of the member 4 is kept constant. For example, when the carriage 1 approaches to the line WL, the member 4 is retracted by overcoming the force of the spring, and increases the output of the detector 5, by which the motor M is run forward and a steering mechanism 2 is turned to the right. At this time, a supporting member 7 is turned around the vertical shaft L, and both rollers 9 abut on the work surely, whereby the torch position is maintained constant at all times.

Title: Adaptive processor and active noise controller
Inventor: TOYODA SHIGEHARU
IPC: H03H21/00
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To make it possible to update I/O characteristic even if calculation does not end within a fixed period by asynchronizing with sampling a point of time for updating an input-output characteristic of a digital signal processing system and determining it according to a scale of the digital signal processing system and an arithmetic capacity of an adaptive processor. SOLUTION: Creation of muffling wave signals y1 (t) and y2 (t) done by a muffling wave signal creation part 12 are executed at each sampling cycle. An adaptive processing part 13 updates filter factors by using a reference signal x(t) and an error signal at the time of starting updating the filter factor. Updating of the adaptive filter factor performed by the adaptive processing part 13 is executed asynchronously with sampling, and once the filter factor has been updated, the next updating is executed in no time. Thus, since the filter factors are asynchronously updated with the sampling clock, time limitation is eliminated for updating the filter factors. As a result, muffling becomes possible even if updating of filter factors does not end in one sampling cycle.

Filed: 1984-02-28
Abstract: PURPOSE:To form continuous pattern on a substrate having a comparatively large area by holding a substrate to which a pattern is transferred by a holder on which two or more alignment marks arranged in the predetermined positional relation are formed. CONSTITUTION:The alignment marks 4a, 4b, 5a, 5b are formed on a holder 3 and these are positioned in the predetermined positional relation each other for the center line C of pattern transfer region 1.

Thereby, the pattern forming element formed on the mask 6A is transferred to the upper half region of the pattern transfer region 1. Next, similar pattern transfer is carried out for the lower half region of pattern transfer region 1.

Title: Solenoid valve
Inventor: TOMITA TORU
IPC: F16K31/06
Filed: 1994-02-07
Abstract: PURPOSE:To moderate impact of a valve element and stablize operation of a plunger by energizing the valve element provided on the end of the plunger towards its end and causing a flange formed on the plunger to abut on the body. CONSTITUTION:A solenoid valve is composed of a solenoid section 30 on the upper half and a valve section 40 on the lower half. When a coil 32 is electrified, magnetic field is generated on an iron core 35 in the vertical direction to thereby attract a plunger 1 to the iron core 35 against a return spring 46. As a result, a valve element 3 separates from a valve seat 2 and two ports 41, 42 mutually communicated with each other through a valve chest 43. When electrification to the coil 32 is cut off, the plunger 1 is returned to the lower part shown on the drawing by the return spring 46. In this case, the plunger 1 causes a flange 7 to abut on an abutting point 8a of the body 8. The valve element 3, which is made of a fluorine-contained resin, moderates the impact at the time of abutting on the valve seat 2, by an inner spring 5.

IPC: G06F9/48
Filed: 1992-02-21
Abstract: PURPOSE:To provide the processor which can quickly process the processing of a lower priority level after changing this level to a proper level with a simple means. CONSTITUTION:When a start signal is inputted from a main CPU at each (ms) in this example, the priority level of the TITM processing is raised. The TITM processing is carried out in preference to the ASR1 or TOVF processing that has the same priority level as the TITM processing. Thus, the TITM processing is accurately carried out with no time delay caused end also synchronously with an external start signal. Therefore, it is not required to always monitor the TITM processing with software and this processing can be carried out with a simple means.

Title: Random access memory
Inventor: ISOBE MITSUO
IPC: G11C7/12
Filed: 1984-02-27
Abstract: PURPOSE:To avoid the overlap between a precharging action and a memory writing action by controlling a writing circuit according to a signal showing a precharge state and a writing control signal. CONSTITUTION:A precharge control signal PS is supplied from a precharge control circuit 12 via a precharge control circuit 15 to show the precharge control state of the circuit 15. While a writing control signal WS is supplied from a writing control circuit 17. A synthesizing circuit 21 receives those signals PS and WS and produces an output MPS to control a writing circuit 16. The output MPS is set at a low level as long as the signal PS is kept at a high level and even though the signal WS is kept at a high level. Therefore no overlap is produced between a precharging action and a memory writing action. Then no writing is carried out to a memory during a precharging action although a writing signal WI is supplied to the circuit 17 simultaneously with or immediately after an input change of an address signal. This prevents a malfunction caused inside a random access memory.
