Title: Self-propelling truck
Inventor: OKAWA IKUO
IPC: B60L11/18
Filed: 1986-07-02
Abstract: PURPOSE:To eliminate the need for the exchange of a battery for a self propelling truck by mounting a feed rail for a current collecting rail to the whole or one part in the travelling path of the self-propelling truck. CONSTITUTION:A current collecting rail 2 is set up to the base of a self- advancing truck 1, and a feed rail 3 is installed to the travelling path of the self-propelling truck. When there is not feed rail 3 on the travelling path of the self-propelling truck, a controller 7 for a stepping motor 9 and a motor 8 for travelling is supplied with power from a battery 6 through a power changeover unit 5a. When there is the feel rail 3 on the travelling path of the self-propelling truck, the battery 6 and the controller 7 are fed with power from a collecting brush 4 through power changeover units 5a, 5b. Accordingly, the exchange of the batteries for charging is unnecessitated.

Title: Crystal oscillator
Inventor: TAKEYASU YOSHIYUKI
IPC: H03H9/05
Filed: 1992-06-16
Abstract: PURPOSE:To improve the frequency stability by forming a lead wire with a metallic sheet spirally, and also, so that the spiral direction is reversed on the way. CONSTITUTION:A lead wire 2 for holding a crystal resonator 1 is made of a metallic sheet having elasticity. A shape of the lead wire 2 is spiral, and the spiral direction is reversed on the way. A vessel 3 contains the crystal resonator 1 and the lead wire 2. By elasticity of the metallic sheet and a shape wound spirally, springiness is generated in the lead wire 2. As a result, even if mechanical vibration is applied to the vessel 3, it is attenuated by the lead wire 2, and the mechanical vibration is not transferred to the crystal resonator 1 itself. Also, since the spiral direction of the spiral lead wire 2 is reversed on the way, magnetic fields generated in the opposed lead wires 2 negate each other in a U-shape part. As a result, in the lead wire 2, no stray inductance is generated. Accordingly, the frequency stability is improved.

IPC: B32B7/02
Filed: 1990-06-15
Abstract: PURPOSE: To obtain a high heated-water sealing strength, a wide impulse sealing range and a high breakdown resistance by a constitution wherein an irradiated inner layer contains an antioxidant in an amount sufficient for adjustment to a specified melt flow index, while an irradiated outer layer has a specified melt flow index, and the ratio of the melt flow index of the inner layer to that of the outer layer is specified. CONSTITUTION: An antioxidant crosslinking inhibitor is added to a heat-sealable inner thermoplastic layer of a multilayer film in the form of a tubular article. The antioxidant is added in an amount sufficient for adjusting the melt flow index of the layer in a state of being irradiated to about 0.5 at least. Besides, the melt flow index of an outer thermoplastic layer in a state of being irradiated is adjusted to be smaller than about 0.7. These adjustments are conducted so that the ratio of the melt flow index of a first outer layer to that of a second outer layer be about 1.5 at least. The antioxidant used herein is blended with a polymer to be made into a crosslinking inhibitor which brings about a crosslinked product having a higher melt flow index than the same polymer having no chemical composition and being at the same exposure level, on the occasion of being irradiated.

Title: Heating element controller
Inventor: SAKO KENICHI
IPC: G05F1/45
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of the power change of a heating element when the voltage fluctuation of an AC power source is caused by providing a phase control circuit to change a phase in accordance with detected voltage and a temperature controlling part to control the energizing of the heating element. SOLUTION: A photo-triac coupler 10 is turned on by a trigger signal from the temperature controlling part, so that a first energizing means starts turning-on at a halogen lamp(heating element) 1. A photo-triac coupler 11 is turned on by the trigger signal from the temperature controlling part after turning on for a specified time, so that it is switched to a second energizing means. When AC voltage is changed, the input currents of the photo-couplers 29 and 30 are changed by the shunt regulator 27 of the phase control circuit, so that the impedances of photo-transistors 29b and 30b(voltage detecting circuits) which are outputs thereof are changed. The change of the impedance changes the energizing phase of the second energizing means. An energizing angle supplied to the lamp 1 is made small or large by the second energizing means, so that lamp power is stabilized.

Abstract: PURPOSE: To improve the transportation efficiency by a traffic control device by grouping vehicles and target patterns according to their attributes to prepare a correspondence of the groups and applying a traffic command such as departure and stop patterns or the like to a vehicle controller.  
     CONSTITUTION: A target assignor 8 specifies, upon reception of the attribute of a vehicle and information of its starting point, a target approaching the starting point at that time and stores a target pattern composed of the target of the same attribute as the vehicle produced after the specified target in a pattern memory 6. The assignor 8 further retrieves the target to be traced by the vehicle from the target patterns when the vehicle starts from the starting point or stopping position and the berth to be stopped at the stopping position to dispatch it to a starting and stopping controller 12 to allow the controller 12 to output a stop pattern to a vehicle controller 1. Since this device thus applies a traffic command to the vehicle controller, it can shorten and equalize the running time of the vehicles and put a stable transportation into practice.

Title: Optical frequency stabilizing device
Inventor: ODA KAZUHIRO
IPC: H04B10/564
Filed: 1989-06-19
Abstract: PURPOSE:To stabilize the relative frequencies of optical FSK signals of many channels by using an optical filter which varies in transmissivity periodically with the frequency of incident light as an optical discriminator where points having the same discrimination characteristics appear periodically about the incidence frequency. CONSTITUTION:This device is equipped with a channel selecting filter 14 as a selecting means which selects the sent optical FSK-modulated signal of one of transmission lasers LD1 - LDn and the optical discriminator 16 as the light filter which inputs the output light of the channel selecting filter 14, and varies in transmissivity with the frequency of the incident light at a period equal to the center frequency interval of the optical FSK-modulated signal. A channel to be stabilized can be switched at high speed by using the frequency selecting filter without using a laser diode for sweeping, and the limit of the number of channels is relaxed. Consequently the center frequency intervals of the optical FSK-modulated signal which has, for example, a 600Mb/s transmission bit rate, 100Hz channel intervals, and >=100 channels are stabilized by one device.
