Title: Optical disc device
Inventor: WATANABE MASAYOSHI
IPC: G11B33/14
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To minimize the infiltration of dust, vibration of the pickup against vibration from the outside and a temperature rise and to prevent malfunctioning and a reduced life, by shielding and sealing a drive section containing an optical pickup and an optical disc part from the outside to be supported by an elastic body and also shielding from an heat-generating source. SOLUTION: A transfer mechanism section 4 incorporates a rotary part rotating while holding an optical disc and an optical pickup part for reading a signal of the optical disc and is fixed to a mechanical cover 7 with screws through an elastic body 6 such as rubber cushion. A door 18 is opened with a hand to insert a disc cartridge 3. Then, the transfer mechanism 4 draws the disc cartridge horizontally, lowers to mount the optical disc on the rotary part and the door 18 automatically closes by a force of a spring to be kept in close contact with a chassis 15. The optical pickup part is shielded by the mechanical cover 7 from a heat-generating source within the chassis 15, for example, a substrate 16 on which electric parts generating heat during the operation are mounted and a power source transformer. This can prevent malfunctioning caused by the infiltration of dust and heat in the outside air, thereby achieving higher reliability.

Title: Device for moving and tilting bed of autotruck
Inventor: YAMADA KOUZOU
IPC: B60P1/04
Filed: 1980-03-17
Abstract: PURPOSE: To prevent a bed from being quickly moved and stopped and eliminate the rattling of the bed, by providing a buffer mechanism, guide rails and flanged rollers.  
     CONSTITUTION: When a hydraulic cylinder 10 is retracted, a bed 2 is moved backward. When the center of gravity of the bed 2 is displaced beyond the position of the pivot 8 of a roller fitting frame 7, the frame 7 is turned over about the pivot 8 as a fulcrum so that the bed 2 is tilted. At that time, oil 21 in a return chamber 20 reenters into the lower chamber of a cylinder 14 through lower small holes 18 because the piston 17 of a buffer and stop mechanism 12 slides while pushing oil 21 in the upper chamber of the cylinder 14 toward the return chamber 20. The piston 17 slowly slides because of the throttle effect of small holes 18. The sliding speed is gradually reduced to zero because the number of upper small holes 18 decreases according as the piston 17 moves upward in the cylinder 14.

Title: Ion beam deposition
Inventor: KASAI TOSHIO
IPC: C23C14/24
Filed: 1978-03-22
Abstract: PURPOSE:For ion beam deposition of nonconducting material, a part of ion beam is collided with the inner face of the barrier to produce secondary electrons, both of the ions and electrons being projected onto the target to be neutralized there by exchanging electric charges. CONSTITUTION:A plasma 2 is formed by electron bombardment or the like in the chamber 1 filled with vapor to be deposited at a specified pressure. A high negative voltage is applied to the extracting electrode 5 which extends from the positive ion port 3 into the process chamber 4 to draw ion beam into the chamber 4. A part of the ion beam 6 is hit against the internal wall of the current pass barrier 7 having holes, producing electrons. The emitted secondary electrons and ion beams 8 are collided to the target 9 and neutralized while forming the deposited material 10. The applying voltage to the barrier plate 7 is limited by the ion collosion. Therefore, it must be lower that the potential of the plasma 2. About the same voltage as the draw voltage of the ion 6 is sufficient.

Filed: 1987-02-16
Abstract: PURPOSE:To change a display area into another desired one with an 'one-touch' operation by having the input of the normalized analog value so that the relative positions of the display request areas are indicated in all produced documents. CONSTITUTION:When a display area is changed during production of a document, the normalized analog value is inputted via a slide switch 9.

The CPU 1 calculates the interim volume of the document covering a range between thee storing head position of a document file in a flexible disk 4 and a display request area. Then the calculated interim volume of document is added to the storing head position of the document file read out of a memory 2 for calculation of the head line of the display request area. A display control part 5 receives the information on the head line of the display request area and transfers the documents equivalent to the capacity of a video RAM 3 following said display request area to the RAM 3 from a document file in the disk 4.

Title: Treatment apparatus for polluted water
Inventor: KON MASAHIRO
IPC: C02F3/06
Filed: 1979-03-20
Abstract: PURPOSE: To perform clarification treatment of polluted water with high efficiency by peeling off biological membrane adhered without discontinuing operation by using an operation involving the stretching and contraction of filler and the regulation of circulating flow rate of polluted water.  
     CONSTITUTION: During the continuation of polluted water treatment operation, the biological membrane adhered to the filler layer 3 is gradually grown. Then, at a time when the lowering of the clarification efficiency is not yet pronounced, the guide roller 7 is moved along the rail 8 and at this time the filler layer 3a is contracted and also the filler layer 3b is stretched, whereby the sectional area of polluted water circulation path formed in the filler layer 3a is made smaller, and also because the air supply pipe 6 or the flexible pipe through which aerated polluted water is supplied is moved according to the moving amount of the guide roller 7, the circulating flow rate of polluted water passing through the filler layer 3a is made greater. Thus, the increment due to overgrowth of the biological membrane adhered to the filler layer 3b can be peeled off. On the other hand, in the filler layer 3b, biological membrane becomes able to grow. Thus, the growth and removal of biological membrane can be attained concurrently and with high efficiency by alternately moving the said guide roller 7 at a regular interval of time.
