Title: Thin-film measuring device
Inventor: KAWANAKA HIROYUKI
IPC: G01N25/16
Filed: 1997-11-18
Abstract: PROBLEM TO BE SOLVED: To efficiently measure and evaluate the thermal expansion coefficient or Young's modulus of a thin film with fewer man-hours by an inexpensive device. SOLUTION: A thin film to be measured is formed on the upper or lower surface of a plurality of substrates with different thermal expansion coefficients and at the same time known Young's modulus and Poisson ratio while being sufficiently thinner than the substrate, and a plurality of samples 16 to be measured are prepared. The sample 16 is accommodated in a sample rest 12 and at the same time is covered with oil 18. Then, when the sample 16 is heated by a heater 14, shape change is measured by a feeler 22 of a surface displacement meter. Temperature is measured by a thermocouple 20. The measurement results are supplied to a computer 24 for calculating and evaluating the thermal expansion coefficient or Young's modulus.

Title: Vertical contour correction circuit
Inventor: NAGAI KENICHI
IPC: H04N5/208
Filed: 1989-12-21
Abstract: PURPOSE:To avoid addition of vertical contour correction to a level lower than a pedestal level by comparing a video signal after vertical contour correction with a video signal before vertical contour correction and selecting a larger level. CONSTITUTION:A gain of a vertical contour correction signal is adjusted by a gain adjustment device 7 and inputted to an adder circuit 8. The adder circuit 8 adds a 1H delay signal and the vertical contour correction signal (d) subject to gain adjustment to obtain a video signal subject to vertical contour correction. The output of the adder circuit 8 is inputted to a clamp circuit 10, where the signal is clamped at a prescribed DC voltage. The 1H delay signal (b) is inputted to a clamp circuit 9 and clamped at an equal DC voltage to that by the clamp circuit 10. Outputs of the clamp circuits 9, 10 are inputted respectively to a maximum value detection circuit 11 and a larger level signal is outputted selectively. Thus, no vertical contour correction is applied to a level lower than the pedestal level and the signal subject to vertical contour correction in a white level direction only is obtained.

Title: Valve system for internal combustion engine
Inventor: HORIUCHI SHIGEAKI
IPC: F01L1/26
Filed: 1994-12-16
Abstract: PURPOSE: To eliminate a guide mechanism and an adjuster from a valve bridge, in a valve system for an internal combustion engine to simultaneously operate two valves by one valve bridge. CONSTITUTION: A roller 25 is attached at the end part of a rocker arm 1, and a valve bridge 4 is downwardly pressed by the roller parts of the roller 25. Even though force in a lateral. direction is applied to a downwardly pressing direction by the arc movement of the rocker arm 1, the roller 25 is only rolled by the force so that the force is not transmitted as such force that the valve bridge is moved in the lateral direction. Therefore, a guide mechanism to resist the force in the lateral direction, is eliminated from the valve bridge 4. Also, recessed bottom surfaces of the sleeves 4-1, 4-2 of the valve bridge 4 are flattened, and end surfaces of valve rear end parts, which are brought in contact with the recessed bottom surfaces, are spherically formed, and both surfaces are brought in contact with each other in a point on the spherical surfaces.  Even thought step differences occur in the positions of the valve rear end parts, contact points are moved only in the other point on the spherical surfaces, and a contact way is not changed, so that step difference adjusting means such as an adjuster, etc., is no more required.

IPC: H04L7/00
Filed: 1989-12-22
Abstract: PURPOSE:To eliminate necessity for installing a clock source from another network near a central synchronizing node by belonging a clock for transmission at the first terminal housing node to a clock for synchronizing from the other network and setting the clock for transmission as the clock source of a ring. CONSTITUTION:Synchronously with the clock for synchronizing from the other network, a first terminal housing node 10 executes transmission to the ring and by using this reproduced clock, another second terminal housing node 2 executes transmission to the ring.

Title: Heat-cooking utensil and mounting method for container in its case
Inventor: ASAHINA TAKASHI
IPC: F24C15/16
Filed: 1988-12-28
Abstract: PURPOSE:To obtain a heat-cooking utensil with easily cleanable structure and good sanitary conditions as well as simple connections, easy removability, and sure torque transmission, by a method wherein a container is fitted with its foot projections and magnetic attraction, and torque is transmitted with simple bars formed almost in tetragon. CONSTITUTION:Connecting bars 3 formed almost in tetragon are fitted on a container mounting base 5 at the bottom of a heating case, and insert holes 12 for connecting- projections 4 located at the foot of the container are formed in the bars 3. After the projections 4 are inserted into the holes 12, a permanent magnet 13 buried under the container mounting base 5 attracts a ferromagnetic metal plate 14 as its corresponding place, and fixes the container. On the other hand, when the features of the container 1 and the connecting bars 3 are formed almost in tetragon, setting and removing the container 1 is easy, and backlash by friction and a trouble getting out of place are prevented since the corners of the bars bear the torque. Since the mounting width between the bars 3 at open side of the heating case 11 is wider than that at back side, finally, the container is exactly fixed between the bars 3, even if casually fitted without confirming the place of the bars 3.

Title: Slide bearing
Inventor: KONISHI MASAHIDE
IPC: F16C27/06
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To prevent a mechanism to check a circumferential directional slide of a sliding body and a shock absorbing material from hindering the shock absorbing action of the shock absorbing material by forming a key groove in an overlapping part of the sliding body and the shock absorbing material. SOLUTION: In a slide bearing, a key groove 71 long in the shaft direction is formed in an overlapping part of a cylindrical retainer 31 of a sliding body 3 and a shock absorbing material 2. A circumferential directional slide of the sliding body 3 and the shock absorbing material 2 is checked by fitting a key 7 long in the shaft direction to this key groove 71. The key 7 does break even when a large load is applied to the key 7, since the cross-sectional area of a part to receive a load caused by a slide of the overlapping part becomes large when a circumferential directional width dimension of the overlapping part is lengthened.  Therefore, a mechanism to reliably check a slide of the overlapping part of the sliding body and the shock absorbing material as well as to check a circumferential directional slide of the sliding body and the shock absorbing material, can prevent the situation of checking the shock absorbing action of the shock absorbing material.

IPC: H01L23/29
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To continue light emission even after the supply of power to a chip is stopped by dispersing light accumulating fluorescent grains in a transparent member installed near a chip. SOLUTION: Light accumulating fluorescent grains 14 are dispersed in a transparent member 13 installed near a chip. The grain diameter and the content of the fluorescent grains 14 are determined by a dispersing characteristic and a light accumulating characteristic of the fluorescent grains 14 against the transparent member 13.
