Title: Air cleaner device for clean room
Inventor: MUKOGAWA YASUKAZU
IPC: B01D46/00
Filed: 1989-02-03
Abstract: PURPOSE:To enable a circulating air to be passed without being passed through a purifying agent filter by a method wherein a bypass passage having a purifying agent filter is connected in the midway of a circulating passage for circulating air to an air supplying filter and a damper is provided. CONSTITUTION:A bypassing duct 21 is connected in parallel with a circulating air conditioning duct 9. Its both ends arc connected to the duct 9. A purifying agent filter 22 removes gaseous and molecular obstacles. This filter 22 is installed in the duct 21 so as to shield an air passage. Two filters 22 are arranged side-by-side along an air flowing direction. An automatic damper 23 may selectively feed air to the duct 21 and the duct 9. A sensing member 24 may detect it gaseous or molecular obstacles are mixed in a circulating air conditioning system. Rough particle filter 26 is arranged at a downstream side of the filter 22 within the duct 21. A pressure sensor 27 may detect a pressure within the duct 21. The sensor 27 is arranged between an inlet port and an outlet port of the duct 21 and each of the filters 22 and 26. Each of them is connected to a controller device 25.

IPC: B21D31/06
Filed: 1980-03-04
Abstract: PURPOSE: To improve practical performance and economic efficiency by bending and forming recessed parts in a sheet surface by the relative copying movement of a hammer rod which is making hammering action at high speed along the predetermined rugged patterns of the material surface, and driving this copying movement based on the plane coordiante values of the patterns having been stored in a computer.  
     CONSTITUTION: A material 5 is placed on a working table 8 in the state that is is sand wiched by the hammer rod 12 of a punch press 6 and a cradle 13, thence it is chucked in the carriage 9 placed at the base point of the plane coordinate base line of the table 8. A computer 10 is placed alongside the press 6 and patterns of rugged sectional shapes have beforehand been stored therein. When working operation is commanded, the material sheet 5 chucked to the material supporting fitting 4 freely slippable on the cradle 8 is lifted by supporting rolls 3 which are likewise moved vertically by commands, then the carriage 9 operates and makes copying movement. At the same time, the driving mechanism of a turret device 7 operates and moves the hammer rod 12 vertically, thereby forming required rugged patterns in synchronization with the above-mentioned intermittent copying movements.

Filed: 1980-03-03
Abstract: PURPOSE:To obtain the optical isolator suitable for mass-production with small size, by constituting electro-optic crystal having the crossing finger electrode inserted between the light source and the photodetecting device. CONSTITUTION:On the electro-optic crystal plate 11 made of lithium niobate, the crossing finger electrode 15 is provided with photolithography, and the high frequency voltage generating section 14 is connected to the electrode 15 at the incident side 20 of the crossing finger electrode 15. When circular polarization beam 12 is incident to the crystal 11, the diffracted light 16 having the horizontal polarized plane 17 and the straight light 18 having the vertical polarized plane 19 are emitted. When the circular polarized wave is incident inversely, the diffracted light having the vertical polarized plane and the straight light having the horizontal polarized plane are emitted. The light incident to the reflection preventing element 35 (crystal 11) from the semicondutor laser beam source 31 via the rod lens 33 is emitted to the optical fiber 37 via the rod lens 36. The light reflected at the fiber 37 does not go inversely through the same path, then it is not fed back to the laser beam source 31. Thus, the isolator suitable for mass-production with small size can be obtained.

Title: Signal correcting device
Inventor: EJIRI KOUICHI
IPC: H04B3/06
Filed: 1981-02-25
Abstract: PURPOSE:To increase the estimated value of forecasting restoration by setting a correcting function as the convolution of a small-digit correcting function and by adjusting the coefficient of the small-digit correcting function in a signal correcting device which forecasts and restores a signal, deformed on a transmission line, to an original signal. CONSTITUTION:A correcting function i(k) is resolved into small-digit correcting functions p1(k1), p2(k2), p3(k3)... having small expansion. For example, when p1(k1)={b1, b2, b3}and p2(k2)={c1, c2, c3}, the convolutions of the p1(k1) and p2(k2) have{c1b3, b2c1+b3, c2, b1c1+b2c2+b3c3, b2c1+b3c2, b1c3}as a coefficient. For obtaining a forecasted and decoded signal f'(j) by using this function, the estimating circuit 50, when discriminating a small difference between original signals f(j) and f'(g), leaves the coefficients of correcting circuits 51-53 as they are without sending a command; when the difference is great, one coefficient b1 of the circuit 51 is increased by an extremely small value DELTAb1.

Abstract: PURPOSE:To adjust the position of a magnetic head in the unit of several mum with a simple constitution by forming a thread groove in a bearing part and a bearing-fixing part which are energized by a lead screw. CONSTITUTION:In the peripheral side surface of the bearing part 3, external thread is formed, and in the side surface into which the lead screw 1 enters of the part 3 are four notched parts 4 formed at every 90 deg. of angle. In the fixing part 2, an internal thread is formed to accommodate the engagement of the part 3.
