Title: Trimming device for vessel propulsion machinery
Inventor: HANDA KENICHI
IPC: F02B61/04
Filed: 1987-03-06
Abstract: PURPOSE:To reduce the contact area between a load receiver and a trim rod of a propulsion machinery main body so as to reduce a slip phenomenon and to suppress the generation of stick by forming groove in the direction of the trim rod movement at least at one side of the contact between them. CONSTITUTION:The tip 14a of a trim rod 14 is formed in a spherical surface and contacted to a load receiver of the main body 6 of an outboard motor through a thrush receiver 15. In the thrust receiving part 15a of the receiver 15, a contact 15c to contact with the tip 14a of the rod 14 is formed in a long ellipse in the moving direction of the rod 14 when a tilt made, that is, in the sliding direction of the rod 14, and its surface is made in a convex at a specific curvature, On the contact of the contact 15c of the thrust receiving part 15a, numerous groove 18 are formed parallel in the moving direction of the rod 14 respectively, and thereby, the contact area between the tip 14a and the contact 15c is reduced while the contact 15c is kept contacted successively to the tip 14a of the rod 14. Therefore, a slip phenomenon in the sliding condition can be reduced, and the generation of stick is suppressed to prevent the generation of abnormal sounds.

Title: Intermediate potential generating circuit
Inventor: TOMISHIMA SHIGEKI
IPC: H03K19/0948
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To provide an intermediate potential generating circuit, which is stably actuated even in a low power-supply voltage and can be easily designed. SOLUTION: A reference potential generating circuit 1 comprises P-channel MOS transistors 2 and 4 constituting a resistance element and N-channel MOS transistors 3 and 5 constituting a diode and outputs a reference potential Vcc/2+Vthn. An N-channel MOS transistor 7 charges an intermediate potential Vcc/2 to an output node N 7 on the basis of the reference potential. A discharge circuit, which consists of MOS transistors 8 and 9, makes a prescribed current flow out from the node N 7. As the resistance element constituted of the P- channel MOS transistors, which are difficult in reducing a threshold voltage Vthp, does not comprise the diode, a reduction in a power-supply voltage of an intermediate potential generating circuit becomes possible.

Title: Misoperation preventing device for camera
Inventor: SHIOZAWA KAZUO
IPC: G03B7/30
Filed: 1981-04-08
Abstract: PURPOSE:To prevent malfunction of a camera, by avoiding the operation of a magnet for shutter opening, if a trigger switch is not set to an operationable prescribed state. CONSTITUTION:In the operation of release, if a trigger switch TG is not in an operationable initial state, since the trigger switch TG is turned off, even if a release switch S2 turns on with a winding up switch WE turned on, a switch signal output circuit GC does not output a release signal to a control circuit SC. Thus, the control circuit SC does not turn on shutter opening magnets beta and alpha with a driving circuit DR, does not output a sequence end signal, and does not keep on-state by grounding the base of a transistor T2. That is, no exposure sequence is made. Thus, the malfunction of a camera can be prevented.

Title: Surface oxidation treatment for copper
Inventor: YAMAMOTO HIDEO
IPC: C23C22/63
Filed: 1987-03-09
Abstract: PURPOSE:To form an oxide film having a uniform color tone, by increasing the concentration of hydroxide with increasing treated area of copper per quantity of treatment solution at the time of treating the surface of copper with a treatment solution composed principally of chlorite and hydroxide so as to form an oxide film. CONSTITUTION:The surface of a copper plate is cleaned by etching, which is immersed into a treatment solution containing chlorite such as NaClO2, KClO2, etc., and NaOH and KOH of 0.10-0.50mol./l concentration to undergo surface oxidation treatment. At this time, when the treated area of the copper plate per quantity of treatment solution reaches 0.2-0.5m<2>/l, the concentration of NaOH and KOH is increased at a rate of 0.025-0.075mol./l and the concentration is regulated to 0.175-0.575mol./l. Further, when the treated area per quantity of treatment solution reaches 0.4-1.0m<2>/l, the concentration of NaOH and KOH is increased to 0.20-0.65mol./l.

Title: Unit injector
Inventor: TAKAHASHI TAKASHI
IPC: F02M51/00
Filed: 1989-03-06
Abstract: PURPOSE:To make any combustion gas not flow around a needle by setting up an overflow restraint, which restrains any overflowing action of fuel flowing in a fuel overflow passage when fuel injection should be stopped and checks a drop in fuel pressure in a fuel pressurized chamber, in the fuel overflow passage. CONSTITUTION:When a piezoelectric element 67 is contracted to stop fuel injection, fuel pressure in a pressure control chamber 55 goes down and an overflow valve 31 moves to the right at once by dint of a compression spring 46, whereby this valve 31 separates from a valve seat part 40 and opened. If so, high pressure fuel in a fuel pressurized chamber 15 is sprayed to the inside of a first fuel overflow chamber 43 via a fuel overflow passage 49 and a pressurized fuel intake chamber 42. However, since a throttle 48 is set up in a fuel passage 45 of the valve 31, fuel in the chamber 43 slowly overflows in a second fuel overflow chamber 44, so that fuel pressure in a needle pressure chamber 18 and a ring passage 19 slowly goes down as well. When a needle 4 closes a nozzle 3, fuel pressure in the chamber 18 and the passage 19 is relatively high, thus fuel gas will not flow into the passage 19 via this nozzle 3 at all.
