Title: Change gear and steering system
Inventor: MARUYAMA RYOICHI
IPC: B62D11/18
Filed: 1987-08-25
Abstract: PURPOSE:To obtain continuously variable transmission traveling with a wide speed range for both going-forward and going-afterward by combining a non- stage transmission and a mechanical transmission and connecting a clutch through switching of a going-forward/afterward change-over device. CONSTITUTION:When only the first-speed clutch is connected, a planetary gear 12c, the third speed gear 231 and 24 of the third speed epicyclic gear 12 in addition to a planetary gears 9c, 8c, and 11c of the second speed epicyclic gear 9 are fixed. Right and left hydraulic pumps 4 and 5 are of the variable- volume hydraulic pump, while right and left hydraulic motors 6 and 7 are of the fixed type hydraulic motor. Therefore, the ratio of the volume of the hydraulic pump to that of the hydraulic motor can be varied within the predetermined range. Accordingly, the ratio of the revolving speed of the hydraulic motor to that of the hydraulic pump can also be varied. As a result, the revolving speed of gears 21 and 22 can also be varied. With this contrivance, one can obtain continuously variable transmission traveling of a vehicle by, for example, connecting only the first speed clutch 14 and varying the revolving speed ratio of the hydraulic motors 6 and 7.

Title: Waste time generator
Inventor: TAKIMOTO YOZO
IPC: G05B17/02
Filed: 1986-09-08
Abstract: PURPOSE:To obtain a simple and compact waste time generator by recording digitally plural analog signal inputs to convert the waste time corresponding to each analog input into an address respectively and therefore outputting the waste time to the analog input based on said address value. CONSTITUTION:Plural analog signal inputs are turned into digital inputs by a digital input means in a fixed sampling cycle. The digital data corresponding to those digital signal inputs are recorded in each area of a recording medium having recording areas for said signal inputs respectively. At the same time, the waste time of each signal input is set individually to a waste time setting means. This set waste time is converted into the address value corresponding to the waste time of each corresponding recorded area by a time/address converting means based on the sampling cycle. Then a waste time deciding means decides whether or not those input signals reach each waste time based on the address value corresponding to the waste time and the sampling cycle of the signal input. The result of this decision is outputted to an analog output means.

Abstract: PURPOSE:To improve yield classifying defects as allowable and non-allowable by providing a lighting means for entering light into the outer periphery of a conductive layer of a through hole, a light shielding means, an image signal generation means for generating an image signal of a defective light image and a detection means. CONSTITUTION:When a light is entered into the outer periphery of a through hole 4 to be inspected with a lighting means, if there is any defect in a copper foil 3 of the through hole, namely, a defective plated part 8, light leaks into the through hole 4 via it. When this light falls on the position where an image is formed on the image forming surface with a lens 7, a light image is formed on a photo detector 11. If the defective plated part 8 exists at only a part of the circumference of the through hole, a light image appears at only a part of the photo detector 11 arranged in a ring as bright spot. When the defect covers the entire circumference, the whole part of the photo detector 11 is brightened. An output signal is generated from the photo detector 11 thus brightened and binary coded with a binary coding circuit 14 to totalize the number of the photo detectors 11 detecting a strong light with an addition circuit device 15. The results are compared with a reference value by a comparator circuit 16.

IPC: F16J9/26
Filed: 1991-07-27
Abstract: PURPOSE:To obtain a piston ring for an internal combustion engine excellent in assembling strength by treating the ring to give shape memory at specified temp. CONSTITUTION:This ring consists of a Ni-Ti shape-memory alloy, which is treated to give shape memory at 270-550 deg.C after the alloy is formed into a piston ring. The piston ring having the shape memory effect or superelasticity is assembled to a piston ring groove so that even when deformation is caused due to widening of the aperture, the original shape of the ring can be recovered by heating at temp. over Af point. Or, at temp. over Af point, reverse transformation is caused to give reverse deformation to recover the original form. Thus, the ring has excellent assembling strength. Especially when the ring is required to have wear resistance, a TiN film is formed on the surface of the ring by treating in a nitrogen gas atmosphere. Thereby, the obtd. piston ring has superior wear resistance compared with a conventional one.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of faults due to short circuit caused by a conductive bonding agent used in mounting an electronic component by forming a protruding wall at a barrel part between both electrode parts of electronic component which are bonded and fixed to a mounted land. SOLUTION: For a chip 10, a protruding wall 12 is formed on a bonding surface side of a barrel between electrodes 11 and 11 at both end surfaces. In order to mount the chip 10 on a printed board 40, first a conductive bonding agent is coated on a mounting land 41 of the printed board 40, and the chip 10 is attached on the conductive bonding agent. Then, the printing board 40 to which the chip 10 is attached heated in a furnace, etc., to have the conductive bonding agent solidified, thus the chip 10 is bonded and fixed to the mounting land 41. The protruding wall 12 prevents the conductive bonding agent from flowing from the one electrode side and then contacting the other electrode to form a short circuit.  In addition, silver particles contained in the conductive bonding agent grows into needle-like structure, which prevents from making contact with the adjoining mounting land 41, etc., to form a short circuit.
