Title: Engine output control method based on shoe slip
Inventor: YAMAMOTO SHIGERU
IPC: E02F9/20
Filed: 1988-08-23
Abstract: PURPOSE:To eliminate a shoe slip accurately with engine output cutoff by shifting the engine output from the specified basic mode to a control mode in a gradual manner at a time when a shoe slip factor has exceeded the specified value during farm working operation of an engine mounted vehicle. CONSTITUTION:In an engine mounted on a crawler vehicle of a bulldozer or the like, a high output part of an engine output full performance curve A in the tractive force-velocity diagram is cut off, thereby setting a basic mode B. Likewise, a part of engine output at th time of this basic mode is cut off, thereby setting a control mode C. When a shoe slip factor has exceeded the specified value during farm working operation of the crawler vehicle, the engine output is shifted from the basic mode B to the control mode C by degrees. With this constitution, the engine output is cut off and a car speed is decelerated, thus a shoe slip is eliminated.

Title: Structure of operation part for sand-proof camera
Inventor: TAKARADA TAKEO
IPC: H01H15/02
Filed: 1987-08-25
Abstract: PURPOSE:To easily obtain a sand-proof effect by making facing gaps between a cover part and an operating member smaller than gaps between the operating member and a facing surface except the sliding part of a main body. CONSTITUTION:The facing gaps A1 and A2 between the cover part 1 and the operating member 2, into which sand can enter, are made smaller than the gaps B1 and B2 between the operating member 2 and the facing surface except the sliding part of the main body. Namely, the sand is not prevented from entering by making the operating member 2 in a hermetically sealed state with the cover part 1 which installs the operating member 2 and covers it, but the sand entering from the gaps A1 and A2 formed in the cover part 1 enters into the housing room of the operating member 2 installed to be slided by forming the gaps B1 and B2 wider than the gaps A1 and A2. Thus, the operating member 2 is not influenced by the entering sand in case of sliding.

Title: Communication cable
Inventor: HIRAMATSU KOJI
IPC: H01B7/06
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To prevent breakage of a joint part of connectors and cutting of a pair-stranded wire by giving elasticity to the pair-stranded wire by forming a rectilinear straight part and a curl part, which is curled up like a spring and, in which a stranding pitch of a signal wire is made larger than a stranding pitch in the straight part.

The capacitance of the curl part 15 is adjusted and increased, so that characteristic impedance of a communication cable 20 remains unchanged. That is, a strand pitch of a signal wire 11a constituting the curl part 15 is suitably made larger than a stranding pitch of that in the straight part 17. When the communication cable 20 is pulled by someone's leg being accidentally caught by the communication cable 20, the curl part 15 extend in proportion to tensile force, causing the force exerted on a joint part of connectors 23, 25 and force acting on the straight part 17 to be absorbed, and breakage, cutting, and the like can be prevented.

Title: Jet nozzle device for jet pump
Inventor: SATO MUTSUO
IPC: F04F5/46
Filed: 1986-09-09
Abstract: PURPOSE:To prevent the diffused jet water from colliding with the inner surface of a protective cylinder so as to reduce both wear and damage to the protective cylinder, by constituting the captioned device in such a manner that, as the high pressure water gushes out from a nozzle cylinder, the protective cylinder externally fitted to the nozzle cylinder goes back. CONSTITUTION:When high pressure water gushes out from a nozzle cylinder 1 to a confluent pipe 5 via a high pressure pipe 2, transferred substance like muddy water is sucked from a suction pipe 52 and is discharged. At this time, before the high pressure water gushes out, a protective cylinder 3 is pushed by a spring 6, and consequently the forward end of the cylinder 3 abuts on a stopper 43 of an external cylinder 4. However, as the gushing process advances or as the gushed water begins to diffuse, the gushed water collides with a projection 32 provided on the internal surface of the protective cylinder 3. As a result, the protective cylinder 3 rotates, and a screw groove 33 of the protective cylinder 3 shifts along a thread ridge 12 of the nozzle cylinder 1. In addition, when the protective cylinder 3 rotates counterclockwise, the protective cylinder 3 retreats in the direction reverse to the direction of the gushed water, resisting the pushing force of the spring 6. And, this can prevent the gushed water from colliding with the internal surface of the protective cylinder 3.

Abstract: PROBLEM TO BE SOLVED: To obtain stable frequency characteristics even when a source voltage drops by using a reference signal which has a frequency higher than the frequency of a crystal oscillator when the crystal oscillator is used as a reference frequency source. SOLUTION: A frequency signal fosc is outputted as the reference signal of a 1st PLL loop from the crystal oscillator 101 and a frequency signal fR is outputted as the input signal of the 1st PLL circuit from a CR oscillator 102.
