Abstract: PURPOSE: To provide a filter which continuously supplies purified air to the passenger compartment of a vehicle or the like even under the most severe environmental conditions. CONSTITUTION: A filter comprises an inlet surface 12, an outlet surface 14, walls 30 which constitute a plurality of passages 40 which extend from the inlet surface to the outlet surface and a filtration means for removing impurities from the fluid. The filter preferably can be subdivided into a plurality of layers including an inlet layer, an intermediate layer and an outlet layer. Each layer includes a plurality of cells 50 having the walls 30 with a generally curvilinear shape. A plurality of the passages 40 are preferably in fluid communication with a plurality of other passages. Surface filtration is used to remove the impurities from the fluid flowing through the passages 40. The impurities are retained within the filtration means disposed on the walls as fluid flows through the passages essentially unrestricted even when the removing means is saturated with impurities.

Title: Mounting device for power unit
Inventor: WATANABE KENICHI
IPC: F16F13/10
Filed: 1985-03-30
Abstract: PURPOSE:To reduce an operating shock at the time of selection, by installing a volume- variable working fluid chamber in a position adjacent to an elastic film, while selecting this elastic film to restriction or nonrestriction, in case of a car engine mount. CONSTITUTION:At a high frequency range in roll vibrations of an engine 2, each electromagnet 20 of an elastic film deformation restricting device 21 is kept in a nonfeeding state, and a magnetic fluid inside a working fluid chamber 16 is discharged to a reserve tank 19, thus an elastic film 7 comes into a state of being freely deforma ble. Therefore, fluid movement via a conduit lying between each of fluid chambers 8 is not performed and any shock is absorbed by deformation of these elastic films 7, keeping a roll spring constant low. On the other hand, at a low frequency range, each electromagnet 20 is supplied with power whereby a magnetic fluid is fed to the inside of the working fluid chamber 16, and these elastic films 7 are forcibly pressed to each stopper plate 11 whereby it deformation is checked, thereby aiming at reduction in vibrations with the fluid movement between these fluid chambers 8. In this case, with control of the amount of power feed, a feeding velocity of the magnetic fluid is controllable, therefore an operating shock at the time of selection is reduced and influence to the spring constant is reducible.

Title: Common memory control system
Inventor: SUGITA AKIHIRO
IPC: G06F12/00
Filed: 1984-04-06
Abstract: PURPOSE:To use more efficiently a memory by adding a specific code before and after a data to be changed to prevent competition when the memory is used in common asynchronously and a computer revises the content of the memory. CONSTITUTION:When the compter rewrites the data of the memory MEM, the specific code (SKIP and END) is added before and after the data to be modified and the result is transmitted to a data bus so as to revise the content of the memory. When the specific code SKIP is detected by a decoder section 13, it is transferred to a transfer control section 14, which stops the transfer of data. When the revision of the memory is finished, the decoder section 13 detects the specific code END, gives it to the control section 14, which restarts the data transfer. In this case, an address signal outputted by an address counter section 16 is not affected by the stop of data transfer. Further, the computer can revise optionally the content of memory as required. Thus, the competition of the use of the memory is prevented and the memory is used more efficiently.

Filed: 1989-03-20
Abstract: PURPOSE:To obtain illumination free from brightness irregularities by alternately laminating light transmission plates which have the same directional incident surface and the different light emitting surfaces, and forming a light transmission body. CONSTITUTION:The light transmission plate 5 uniformly reflects light beams made incident from the rear surface 5a on the back surfaces 5c and emits them from the front surfaces 5b. The light transmission body 4 is formed by alternately laminating two sets of right-angled triangle light transmission plates 5, whose front surfaces 5b are reversed each other, and rectangular parallelopiped light transmission plates 6. When the light transmission body 4 is housed in a main body 1, a part of the light beams from the lamp 3 irradiates display bodies 2 where the front surfaces 5b are confronted with each other on the light transmission plate 5. The transmission plate 6 guides the remaining light beams from the lamp 3 to the bottom right under the plate 6 and irradiates the surface. Thus, brightness irregularities is not caused and the thickness of the indicating lamp is thinned without securing the distance between the lamp 3 and the display body 2.
