Inventor: KAWAKAMI KENJI
IPC: G06K7/00
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To solve the problems in which a lid opens naturally since it becomes loose easily, when force is applied by such added effective force of vibration and shock since a screw is made of a hard material, and a battery is not be replaced by a new one when an apparatus such as a coil and a driver is not available, since the battery ends its life and hence needs to be replaced by a new one, where the screw is used to fix the lid that plays a role of fixing and protecting the battery, when replacing the battery of portable equipment requiring waterproofing by a new one. SOLUTION: Since the method for fixing a lid being fixed to a body by manual rotation by using a screw instead of a tool, the entire head part of a rotor is covered with an elastic resin for sealing the periphery of the hole of the rotor, thus simplifying the structure, reducing the number of part items, and easily obtaining waterproof effect. Also, by increasing the shape of the head part for easily rotating the rotor, resistance against external shocks can be improved and design restriction can be reduced.

Title: Radio communication equipment
Inventor: ITAYA EIJI
IPC: H04B1/74
Filed: 1993-11-09
Abstract: PURPOSE:To reduce cost by eliminating the need for an outdoor side RF signal changeover switch and a switch changeover control line in the radio communication equipment having duplicate configuration comprising an active line and a standby line. CONSTITUTION:When a 1st line is used for an active line, a control means 8 controls a changeover switch T to connect a base band signal processing side to a 1st indoor device 1. Thus, a base band signal is modulated by the device 1 for a 1st line in the case of transmission and sent to the 1st outdoor device 3 via a coaxial cable 2 as an IF signal, in which the signal is frequency- converted and the result is sent from a transmission reception common use antenna 9 as an RF signal. Furthermore, in the case of reception, the RF signal from an antenna 9 is frequency-converted at the device 3 and the result is fed to the device 1 via a cable 2 as an IF signal, demodulated and outputted to a processing side as a base band signal. Upon the receipt of an alarm signal from the devices 1,2, the means 8 commands the changeover to a standby line to the switch 7 and the base band processing side is connected to the indoor device 4.

Title: Toothed belt
Inventor: YAMADA MITSUO
IPC: F16G1/28
Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To obtain a toothed belt, having durability, by completely covering at least the surface of a winding string by a normal synthetic fiber string, even in a condition where canvas is extended to be stuck to the engaging surface of a toothed belt. SOLUTION: Since the intermediate string 17 of a high-strength and high-heat- resistant fiber string is spirally wound on the periphery of wadding 16, the wadding 16 can be elastically elongated by pulling. Also, the intermediate string 17 itself, despite having no elongation, can be elongated by the lengthening of the spiral to make a composite string thread 15 have a large telescopic property, thereby easily molding a toothed belt. Since a condition, wherein the surface of a winding string 18 is completely covered, can be maintained even in a condition, where a coating string 19 is wound on the periphery of a winding string and canvas is elongated to be stuck to the engaging surface of the toothed belt, the exposure of the wadding 16 on the surface can be eliminated, thereby inhibiting the deterioration of the wadding 16 or cutting due to abrasion.
