Title: Travel control device for cargo handling vehicle
Inventor: ISHIKAWA KAZUO
IPC: B60W10/10
Filed: 1990-06-13
Abstract: PURPOSE:To alleviate a shock during the selection of travel mode in a travel control device for a forklift truck or the like in the title by correcting a target speed with the deviation, when a deviation between target and actual speeds is within a tolerance, correcting the target speed with the tolerance, when the deviation is outside the tolerance, and adjusting a clutch with the corrected target speed. CONSTITUTION:CPU 24 makes judgement as to whether a cargo handling vehicle is in normal travel or cargo handling travel mode involving the operation of a cargo handling lever 9, on the basis of signals detected with an accelerator sensor 18 and a lever sensor 21. The CPU 24 operates a deviation between an actual speed taken from a speed sensor 17 and target speed calculated on the basis of a stepping amount for an accelerator pedal 19 at the time of travel mode selection, upon judgement that the travel mode is changed over to cargo handling travel mode. When the deviation is within a tolerance, the target speed is corrected with the deviation. Also, when the deviation is outside the tolerance, the target speed is corrected with the tolerance. A corrected target speed is thereby obtained. Finally, the CPU 24 controls a clutch actuator drive circuit 28 in such a way as to keep a travel speed opposite to the corrected target speed.

Title: Drawing of conjugated fiber
Inventor: MATSUMOTO KAZUHIKO
IPC: D01D5/30
Filed: 1995-06-21
Abstract: PURPOSE: To enable uniform drawing of a conjugated yarn while avoiding heat fusion of filaments by cooling the conjugated yarn of a sheath-core or side by side type before or on drawing. CONSTITUTION: Undrawn yarn 4 of a sheath-core or side by side type conjugated fibers are cooled, before or when they are drawn. If the conjugated fibers are cooled down by blowing cool air at about 15 deg. from a nozzle 2 to the yarn at about 600mm/min while giving a vibration to the yarn, the yarn is prevented from generating heat to cause no fusion between filaments. Thereby the drawn yarn is freed from fusion and breakage of filaments.

SOLUTION: When a subscriber telephone set 7a confirms a dial tone, the subscriber telephone set 7a sends a PB signal having an ID code and a password to an exchange 20a. A PBR 23 decodes the PB signal and gives the received ID code and a password to a central processing section 26, and an ID code password reception means 26a confirms them and gives the result to a connection propriety discrimination means 26b. Then a public line-leased line-public line connection available number table 27a is referenced to, so as to confirm the presence of ID code registration and matching/dissidence of the password. When a good confirmation result is indicated, the exchange 20a sends a call tone again to the subscriber telephone set 7a to inform the permission of a private network and receives a connection destination number from the subscriber telephone set 7a to make a normal connection.

Title: Electronic device case
Inventor: KAMIMURA OSAMU
IPC: H05K5/02
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To lessen a compressive force required for compressively deforming a packing and to ensure both an electronic device case of waterproofing and electromagnetic shielding with a small force by a method wherein at least two or more projections which protrude through the opening of a groove are formed on the edge face of the packing on its joint surface side. SOLUTION: A packing 5 is formed like a U shape, and projections 5a and 5b which protrude from a groove 1b are each formed like an edge. When a lid 2 is mounted on a main body 1 as mentioned above, a pressure exerted on the packing 5 so as to bring the joint surfaces 1a and 2a of the main body 1 and the lid 2 into contact with each other can be reduced to 1/2 to 1/3 as small as an ordinary pressure. Therefore, a reaction given from the packing 5 to the flanges 1c and 2 of the main body 1 and the lid 2 becomes small, so that screws can be lessened in number without increasing the flanges 1c and 2c in thickness. Concerning waterproofing, the projections 5a and 5b are brought into contact with the joint surface 2a of the lid 2, so that an electronic device case of this constitution is of multi-waterproofing structure and enhanced in waterproofing effect.
