Title: Evaporated fuel gas exhaustion suppressing device
Inventor: ONO KENICHI
IPC: F02M25/08
Filed: 1988-11-14
Abstract: PURPOSE:To prevent the leak of the evaporated gas when the evaporated gas exceeds an adsorption limit by arranging the intake port of a canister which is filled with adsorbent in the third passage connected to the upstream side of the suction pipe negative pressure part in an internal combustion engine. CONSTITUTION:When the gasoline in a fuel tank 1 reduces, and the internal pressure of the fuel tank 1 increases over the internal pressure of a canister 10, a differential pressure operation valve 21 is opened. Then, the evaporated fuel gas passes through the first passage 11 and flows into the canister 10 and liquefaction-adsorbed onto an adsorbent 15. Further, a throttle valve 9 is opened by the operation of an internal combustion engine 2, and if a negative pressure is generated on the downstream side, a check valve 22 in the second passage 12 is opened. and the evaporated fuel gas which is liberated from the adsorbent 15 passes through the second passage 12 and sucked into a suction pipe 3. At this time, the fresh air necessary for the isolation of the evaporated fuel gas is introduced into the canister 10 through the third passage 13. Further, the evaporated fuel gas exceeding an adsorption limit is introduced into the third passage 13.

Abstract: PURPOSE:To change a reproduced picture quality characteristic and to improve the picture quality of the entirely of reproduced picture by detecting a noise component from a signal in a noise reduction circuit and changing the quantity of the detail of a non-linear detail circuit. CONSTITUTION:A noise detection circuit 200, when the picture having much noise component is reproduced, detects the noise of 800KHz-1.5MHz component visually unseemly by a band pass filter 30 and an 'L' signal is impressed to the control terminal CON of the non-linear detail circuit 33. Accordingly, a switching transistor 338 is conductive and a luminance signal (d) passes a path which is not non-linear detail processed. When the noise component is a little, an 'H' signal is impressed to the control terminal CON of the non-linear detail circuit 16. Accordingly, the switching transistor 338 is not conductive and the luminance signal (d) is non-linear detail processed.

Title: Disk reproducing device
Inventor: YOKOTA TEPPEI
IPC: G11B19/02
Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To reduce the memory capacity necessary for managing artist's names added to disks, respectively, in a reproducing device capable of reproducing plural disks. SOLUTION: An artist's name is inputted and registered in an artist list. An artist number is added corresponding to the artist's name. In this case, the artist's name is recognized without distinguishing a capital letter from a small letter. A housed and reproducible disk is identified by a disk number and an artist number is given to the artist's name corresponding to each disk. Inputing of an artist's name is performed by key operation by a user or a copy extracted from the CD text information. In the artist list, by preventing the duplication of the artist's name and using the artist number corresponding to the disk number, the memory capacity is reduced.

Abstract: PURPOSE:To obtain a lead-base alloy for a storage battery suitable for a grid plate for a maintenance-free battery with an excellent anticorrosion and mechanical strength, by forming the alloy, of calcium, tin, and selenium of specific percentages respectively and lead of the remaining %. CONSTITUTION:A lead-base alloy for a storage battery is made of 0.03 to 0.5 % of calcium, 0.03 to 5.0 % of tin, 0.001 to 0.1 % of selenium, and the remaining % of lead. In this alloy, the calcium is added to improve the mechanical strength of the alloy. When the addition is less than 0.03 %, the mechanical strength cannot be improved, and when more than 0.5 %, a good casting cannot be acquired in a low casting temperature. The tin improves the casting property of the alloy and increases the mechanical strength. When its addition is less than 0.03 %, it can rarely improve the casting property and the mechanical strength, and when more than 5.0 %, the said effect cannot be obtained either. The selenium improves the micronization of the crystal composition and the mechanical strength, and prevents the abrasions at the particle interface. When the addition is less than 0.001%, the improvement from the micronization cannot be observed, and when more than 1 %, the level of the micronization reaches to the saturation.

Title: Two passage type exhaust pipe
Inventor: FURUHASHI KAZUHIRO
IPC: F16L9/18
Filed: 1999-10-08
Abstract: PROBLEM TO BE SOLVED: To prevent the deformation or damage of an upstream section of the partition plate arranged in an inner pipe due to thermal stress in an upstream end section of a two-passage type exhaust pipe connected to an exhaust manifold. SOLUTION: Two passages are formed by arranging the partition plate 4 in the diameter direction in the inner pipe 2, and a holding section 8 whose diameter is slightly reduced is formed at the downstream side of the end section of an outer pipe 3. The outer pipe 3 is fitted to the inner pipe 2, and the holding section 8 is fixed to the outer pipe 3, and a flange 6 is fixed to an end section of the outer pipe 3 to be connected to the exhaust manifold. Since clearance 5a is formed on the upstream side of the inner pipe 2, even if the partition plate 4 is lengthened due to thermal expansion, the end section at the upstream side of the inner pipe 2 is not restrained. This eliminates the cause of stress.

Title: Surface acoustic wave device
Inventor: KASHIWAGI TAKAYOSHI
IPC: H03H9/25
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To improve the weather resistance of a surface acoustic wave device and to facilitate the packaging of the element by forming a film of a material having higher weather resistance than the material of an electrode on the surface of a piezoelectric substrate. SOLUTION: The inter-digital electrodes 25 and 26 of a surface acoustic wave filter element are covered with a prescribed thick aluminum oxide film 25a-2 formed by the anode oxidation. Thus, both electrodes 25 and 26 have high weather resistance and are accordingly not easily eroded, and the finger parts 25a and 26a and the band parts 25b and 26b never have disconnection against the erosion. Therefore, the filter element has high weather resistance. Furthermore, the bonding pads 25c and 26c are covered with an Au film and accordingly have high weather resistance. As a result, the packaging of the filter element is facilitated owing to the high weather resistance of the element itself. Then the production cost of the filter element can be reduced.

Title: Fm receiver
Inventor: ISHIDA KOJI
IPC: H04B1/10
Filed: 1985-12-24
Abstract: PURPOSE:To obtain an FM receiver capable of high sensitive reception while keeping high S/N and high selectivity by controlling FM feedback quantity in response to the level of the FM detection output. CONSTITUTION:The circuit has an FM negative feedback loop so as to decrease the frequency shift of the FM signal passing through an IF filter 3. Since the 1st VCA circuit 6 controlled by the output of a level detection circuit 7 is con nected, the feedback quantity of the FM negative feedback changes in response to the level of the FM detection output. In using the circuit 7 having a character istic shown in figure, when the detection output level is low, the detection output shown in a point A has nearly the same characteristic as that without any feedback shown in solid lines. The 2nd VCA circuit 9 is connected to the output of the FM detector 4 and controlled by a signal corresponding to the output of the circuit 7. Thus, the detection output of a point B is corrected to the original linear characteristic as shown in broken lines in figure.
