Title: Temperature control method for heat roll fixing device
Inventor: SANO YOSHIHIKO
IPC: H05B3/00
Filed: 1990-11-30
Abstract: PURPOSE:To keep the temp. of a heat roll constant by rotating the heat roll by means of the distance of high temp. and low temp. detecting elements on the basis of a signal from the high temp. detecting element and stopping the heat roll at a position where the low temp. detecting element and a sensor heat face to each other, when printing is stopped. CONSTITUTION:The temp. control of the heat roll is carried out with the signal from the low temp. detecting element 17a during the printing, and the heat roll 11 is stopped at the position where the low temp. detecting element 17a and the sensor head 18 face to each other, on the basis of the signal from the high temp. detecting element 17b when the printing is stopped. Therefore, the heat roll 11 is stopped at the position where the low temp. detecting element 17a and the sensor head 18 face each other, following a back up roll 12, when the printing is stopped, and the temp. control of the heat roll is carried out with the signal from the low temp. detecting element 17a at the time of nonprinting. Thus, the temp. control is carried out while the heat roll 11 is stopped at the time of the nonprinting, only by adding a simple circuit, so that the life of a roll driving motor 14 can be prolonged.

Title: Vibration type material feeder in chipper
Inventor: ONUKI TORU
IPC: B27L11/00
Filed: 1989-12-26
Abstract: PURPOSE:To prevent small lubber pieces from being caught between a vibration conveyor and a spout by continuously providing the vibration conveyor to the spout and making the top dead center of the vibration conveyor nearly equal to the top face of the bottom plate of the spout and constituting the end part of the bottom plate of this spout on the ascending slant face directed to a casing. CONSTITUTION:A chipper 1 is rotatably driven and also a crank mechanism 14 is driven and thereby a vibration conveyor 10 is rocked back and forth. In this state, when lubber is introduced in the vibration conveyor 10, lumber is transferred toward the shout 8 because the vibration conveyor 10 is raised at a route approaching the spout 8 as shown in an arrow A while keeping the height shown in a figure as a top dead center and repeats descending action at a receding route. In the meantime, the height is detected by a detector 25 and a fluid cylinder 22 is actuated by this detected signal and a four-row link 17 is rocked back and forth and a supporting arm 20 is raised and lowered along a casing 2. The tip part of the bottom plate 12a of the vibration conveyor 10 is raised and lowered along a descending slant plane 8b while keeping an extremely small gap for the slant face 8b of the bottom plate 8a of the spout 8. Therefore even when comparatively small lubber piece is supplied, it is not caught therebetween.

Title: Infrared therapeutic apparatus
Inventor: MURAI TOSHIO
IPC: A61N5/06
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To improve ease of handling by a method wherein a head casing is formed with one end opened to house a heat source part for radiating infrared rays to an opening and a temperature rise recognizing means is attached on the side of the opening. SOLUTION: A head casing 2 is formed with one end thereof opened and a heat source part B is arranged facing an opening thereof to radiate infrared rays. A temperature rise recognizing means E is arranged at the opening part of the head casing 2. In the temperature rise recognizing means E, a thermosensitive discoloring element 51 is buried into a metal plate 50 and covered sealed with a protective seal 52. The thermosensitive discoloring element 51 herein used should be reversible in nature: it changes in color above a specified temperature and returns to the original color when the temperature falls below the value. For example, the temperature of discoloring is set to about 50 deg.C. The rear of the metal plate 50 is colored in a black system to improve the absorptivity of the infrared rays.  This enables easy confirmation for the reaching of a treating temperature thereby achieving ease of handling.

Filed: 1989-12-28
Abstract: PURPOSE: To attain selection of a route with a very positive proof that the route is idle by comparing idle state of a communication circuit with idle state data of a communication circuit between a destination exchange system and each intermediate exchange system and selecting a call having not idle direct communication path or circuit between a transmission exchange system and a destination exchange system via an intermediate exchange system so as to designate a route for the call thereby distributing route designation capability in each exchange. CONSTITUTION: A transmission or access switch(ASW) analyzes a called number of a call entering a network so as to decide a termination or destination switch(DSW) of this call in the network. In the case that no direct trunk to the DSW is available, the ASW retrieves an idle 2-way link path toward the DSW through the network to decide the route. All idle 2-link routes between the ASW and the DSW are extended to an intermediate switch(ISW), the ASW requests the DSW at first to send a list of switches at a remote end of all trunk groups of the DSW having idle incoming trunks and uses the list received from the DSW to set connection of the 2-way link to this call.
