Title: Back-tension mechanism for uncurling mechanism
Inventor: TAKAIKE YASUAKI
IPC: B65H23/34
Filed: 1994-09-13
Abstract: PURPOSE: To satisfactorily uncurl a recording sheet irrespective of the diameter size of its roll, by applying an optimum back-tension simultaneously with uncurling operation. CONSTITUTION: A shaft securing bracket 3 having an uncurling shaft 1 and a counter shaft 2 between which a rolled recording sheet 9 is fed, is rotated in a direction A about a fulcrum 4 as a center by a drive force depending upon a diameter of the sheet 9, and accordingly, the sheet 9 is squeezed by the uncurling shaft 1 so as to remove a curl therefrom. During this operation, the counter shaft 2 rotated together with the uncurling shaft 1 abuts against a back-tension roller 5 which can be rotated about the fulcrum 4 as a center, so as to clamp the recording sheet 9 between the counter shaft 2 and the back- tension roller 5. An urging force of a coil spring 8 is applied to the back-tension roller 5 in a direction reverse to the direction A, and accordingly, a back-tension force is applied to the recording sheet 9.  The curl squeezing angle and the back-tension force can be optimized following the rotational quantity of an uncurling mechanism 10 in the direction A in accordance with the diameter size of the recording sheet 9.

Title: Optical module
Inventor: TAKADA TOSHIHIRO
IPC: H04B10/40
Filed: 1990-08-20
Abstract: PURPOSE:To obtain the optical module which has desired coupling efficiency and is stable against disturbance such as temperature variation by rotating polarized light by a polarizer. CONSTITUTION:The light which is emitted by a polarized light source 1 and polarized, for example, as shown by an arrow P1 in a figure is made incident on a polarizer 2 whose axis P0 of polarization is at an angle theta to a polarizing direction P1. Then the light which is transmitted through the polarizer 2 is polarized light P2 in the same direction with the axis P0 of polarization of the polarizer 2 and the intensity of the light is a component in a direction matching the axis P0 of polarization of the polarizer 2 in the incident light. Consequently, the intensity of projection light is adjustable by rotating the polarizer 2 on the optical axis (by varying theta) and the desired coupling efficiency and a desired focusing state are obtained independently of each other, thereby obtaining the optical module which is stable against disturbance such as temperature variation, etc.

Title: Air conditioning controller
Inventor: IWATA MASAYUKI
IPC: F24F11/02
Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To avoid troubles, such as a power failure attributable to excess power consumption by storing time lag information from the reception of an ON signal up to the operation starting of an air conditioning device and commanding operation starting of the air conditioning device when the time lag based on this time lag information passes from the reception of the ON signal. SOLUTION: When an integrated control panel 4 transmits an ON signal to an air conditioning controller 3 to turn ON the controller 3, the ON signal is received by the air conditioning controller 3 by way of a signal line. The air conditioning controller 3 transmits the ON signal to a control unit 31 by way of an interface 32. The control unit 31, when it receives the ON signal, reads out time lag from a memory 35 and starts a time lag timer from a program loop or the like. The operation must stand by until this time lag has elapsed and the air conditioning device starts its operation when the time lag has elapsed. Therefore, if various kinds of time lags are stored in a plurality of air conditioning controllers 3, it will be possible to deviate start timing of each air conditioning device when receiving ON signals from the integrated control panel 4.

Title: Process for pyrolytic decomposition of chlorine- containing resin
Inventor: SATO TORU
IPC: C10L5/48
Filed: 1999-08-03
Abstract: PROBLEM TO BE SOLVED: To improve a pyrolytic decomposition rate without dilution or contamination of a hydrogen chloride gas produced through pyrolytic decomposition by feeding hydrogen chloride as a carrier gas into a pyrolytic decomposition furnace. SOLUTION: The pyrolytic decomposition is carried out by feeding a chlorine- containing resin from an inlet, for example, of a rotary kiln-type indirect heating furnace, and heating indirectly from the inside or outside of the kiln to set the inside at an appropriate temperature. The chlorine-containing resin is de- chlorinated during the course of movement through the kiln and is taken out after separation into a carbonized product and a hydrogen chloride-containing exhaust gas. At this time, hydrogen chloride is fed into the furnace as a carrier gas, so that an easy-to-melt substance bled out on the surface of the chlorine- containing resin is forced to be volatilized and can thus be removed. Eventually, the pyrolytic decomposition rate the resin can be remarkably improved. If the feed of the carrier gas is increased, the resultant hydrogen chloride gas is not contaminated, thereby permitting a high de-chlorination rate of the chlorine-containing resin to be achieved.

Title: Intermediate processor
Inventor: HIRAMATSU TATSUO
IPC: H04H20/55
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To provide an intermediate processor for an FM multiplex broadcast receiver in which decode-processing of a ciphered digital signal is realized without revising an interface configuration. SOLUTION: When an interrupt signal INTR1 denoting an end of reception is received from a demodulation circuit to the intermediate processor 100, a control circuit 122 allows a 2nd shift register 126 to output address data designating an output mode to the demodulation circuit. The demodulation circuit outputs a prefix part to a shift register 102, accordingly. An initial value decision processing circuit 112 generates an initial value, based on data of the prefix part. When the generation of the initial value is finished, the control circuit 122 starts input of data in succession to the prefix part. An exclusive OR gate circuit 118 receives a pseudo random number series generated by a pseudo random number generating circuit 114 and the input data, based on the initial value to conduct decode-processing.
