Inventor: OGASAWARA HIDECHIKA
IPC: B66B23/22
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent dropping out of a screw without damaging the design property by injecting an adhesive, which is substantially transparent in a dry state to a through-hole and a screw hole prior to the mounting of the screw, and screwing the screw to the screw hole before it is dried. SOLUTION: In mounting of a screw 7, an adhesive 9 is injected into through- holes 2a, 3a and a screw bore 4a, respectively, prior to the mounting, and the screw 7 is inserted into the through-holes 2a, 3a and also screwed to the screw bore 4a. As the adhesive 9, a one that is substantially transparent, when dried and has an adhesive force will not cause loosening of the screw 7 by the vibration of a passenger conveyor, for example, silicone is used. According to this, the screw 7, an inner deck 3, a skirt guard 2 and a frame 4 can be mutually adhered, and the dropping out of the screw 7 can be surely prevented with superior adhesion. Since the adhesive 9 that becomes transparent when dried is used, appearance can be kept without damaging the design property.

Title: Temperature compensator for ink feeder
Inventor: OOSAKI MIKIO
IPC: F15B1/02
Filed: 1980-03-22
Abstract: PURPOSE: To perform stable printing from the early stage of printing even if the operating temperature difference is large, by varying the external pressure applied to the pressure accumulating chamber with respect to temperature so as to constantly apply the pressure needed for a fixed flow rate of ink.  
     CONSTITUTION: A compensating spring 29 varies the pressure to press a pressure rod 27 with respect to the temperature variation. When the pressure of the ink jetted from the nozzle is maintained at a stationary pressure, the forces of a spring 26 and the pressure rod 27 balance with each other and they stand still. Therefore, if the temperature varies, the pressure of the pressure rod 27 varies with said temperature, causing the pressure in a pressure accmulating chamber 2 to vary so that ink of fixed flow rate is constantly jetted out. In addition, when the operation is at rest, if the temperature varies after the rest, the pressure of the compensating spring 29 varies, causing the pressure in the pressure accumulating chamber 2 to vary with the temperature variation. Accordingly, the period of time needed for the apparatus to reach the stationary state is largely reduced.

The hologram plate 14 converts luminous flux from the LED lamps 1a-1c into one converged light and it is made incident on the light transmission body 3 efficiently.

Title: Spread spectrum communication equipment
Inventor: SAITO KATSUO
IPC: H04J13/00
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To select an antenna regularly by limiting a band of a reception signal with a band filter means whose band is sufficiently narrower than a reception band width so as to detect the reception strength of the reception signal. SOLUTION: A reception signal converted into a prescribed frequency signal by a frequency converter is distributed into a BPF 115 and a narrow band BPF 123. The signal receiving prescribed band limit by the BPF 115 is fed to a variable amplifier 116 and a detector B122. The detector B122 detects the strength of the reception signal of the wide reception band subjected to spread spectrum and a detector A124 detects the strength of the reception signal limited sufficiently to a narrower band (around a center frequency of a reception band). A control section 118 uses a signal S1 from the detector A124 and a signal S8 from the detector B122 and selects an antenna when the level of the signal S1 reaches a 1st threshold level or below or the signal S8 reaches a 2nd threshold level or below.

Title: Recovering method of low-temperature waste heat generated by iron making process
Inventor: SAKAGUCHI MITSUHIKO
IPC: F25B27/02
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To recover low-temperature waste heat efficiently, by a method wherein an adsorption type refrigerating machine, capable of being driven by low-temperature waste heat lower than a specified temperature, is provided at the vicinity of a low-temperature waste heat generating source to generate cold water by driving the machine by the low-temperature waste heat, while the amount of heat is compensated by a high-temperature heat source upon deteriorating the amount of the low-temperature waste heat and generated cold water is reserved once. SOLUTION: When an adsorption type refrigerating machine 2, capable of being driven by a low-temperature heat source of lower than 100 deg.C, is employed and heat source water maintains a predetermined temperature, cold water of a predetermined temperature is produced stably by employing only the cooling water of the waste heat generating source 1 as heat source. When the temperature of the heat source water is lower than the predetermined temperature, a cold water tank 4 is provided so that a cold water temperature will not be raised suddenly even when the operation of the adsorption type refrigerating machine 2 is stopped.  When the cold water temperature is raised gradually and has exceeded the predetermined temperature even when the cold water tank 4 is provided, the amount of heat is compensated by a high-temperature heat source 3 to raise the temperature of the heat source water to the predetermined temperature and the operation of adsorption type refrigerating machine is reopened to output the cold water. According to this method, cold water, having a constant temperature at all times, can be outputted by the necessary minimum heat compensation regardless to the temperature change and the period of the same of the heat source water.

Abstract: PURPOSE:To improve the bonding and cutting of a bundling tape, by forming a bundling swing arm for moving the bonding and cutting unit being the movable side of a bonding and cutting mechanism into a broken-type structure and protruding an extension piece from the upper end of the press plate of a receiving table unit on a fixing side to guide the guide roller provided to the lower end of the bonding and cutting unit to a predetermined position. CONSTITUTION:Since a bundling swing arm 4 has a broken-type structure, even when a bonding acting part 42 is positioned outside the predetermined engaging position due to an engaging means E against the elastic force of a spring 43, a guide roller 24 is brought into contact with a guide piece 25 at the falling time of the bundling swing arm 4 to be guided thereby and the bonding acting part 42 is bent inwardly to reach the engaging position of an engaging means E and the relative angle of a drive part 41 and the bonding acting part 42 becomes a predetermined value while the guide roller 24 at the time of bonding action reaches a predetermined position. Since a press plate 23 is opened outwardly against the elastic force of a spring 27 by the pushing-in of the guide roller 24, the guide roller 24 and the press plate 23 move to the position where the guide roller 24 and a press acting part 23a are brought into contact with each other and the bundling tape between a tape receiving table 21 and the guide roller 24 becomes a linear and almost horizontal state.
