Abstract: PURPOSE:To enable a continuous document to be normally stacked, by a method wherein, the remaining amount of the continuous document stacked in a first stacker is detected every predetermined time, and correspondingly to the remaining amount the feed amount of a second feed means is gradually changed. CONSTITUTION:A continuous document 1 printed by a printing part 8 is fed by a first feed means 4 to be stacked in a first stacker 5 once, furthermore being fed by a second feed means 6 to be stacked in a second stacker 7. At this time, the remaining amount of the continuous document 1 stacked in the first stacker 5 is detected every predetermined time, a feed speed corresponding to the remaining amount is determined at every detection, and the second feed means 6 is driven at a gradually variable speed. In this manner, the continuous document 1 fed at an uncountinuous line feed speed by the first feed means 4, e.g., in a high-speed line feed, is fed at a converted feed speed, i.e., an approximately constant and continuous speed, by the second feed means 6. Thus, the continuous document 1 is orderly folded up and stacked in the second stacker 7.

Title: Consolidating method of powder compact
Inventor: NISHIO HIROAKI
IPC: B28B3/02
Filed: 1991-02-12
Abstract: PURPOSE:To obtain a method for cold isostatic pressing a powder compact with no application of elastic film by a method wherein pressing is applied from the outer surface of swollen particle aggregate, which is prepared by immersing the powder compact made of metal, ceramic or the like in the swollen particle aggregate, which is prepared by absorbing liquid into organic polymer particle. CONSTITUTION:A powder compact 3 is put in a die 1. Then, swollen particle aggregate 2 is cast in the gap made between the powder compact and the die so as to completely imbed the powder compact 3 in the aggregate. A punch 4 is placed on the completely imbedded compact in order to be installed on a uniaxial press. Load is applied on the punch 4 so as to obtain the surface pressure applied on the punch of 1,000kg/cm<2>. After the retention of said load for 5min, the load is released and the contents are taken out of the die. The separation between the powder compact and the swollen particle aggregate is very easy and crack, chipping and the like do not develop in the powder compact. Since the outer diameter at the tail part of the compact is reduced to 59.1mm, the density in crease can be recognized. The penetration depth of the liquid is about 0.1mm beneath the surface of the powder compact. Thus, the penetration of pressure medium in the interior of the powder compact is almost prevented and the density increase can be contrived.

Title: Converting device for process quantity
Inventor: AZEGAMI TADASHI
IPC: G01D5/243
Filed: 1980-02-18
Abstract: PURPOSE:To furnish the converting device not requiring adjustment by a method wherein the output of an oscillator whose frequency changes according to displacement and power is shifted by a shift resistor and the exclusive logic-sum output of the output of a prior-rank bit and the output of a prescribed-rank bit is averaged. CONSTITUTION:The oscillator is constituted by a vibrator V to which a power is given from the prescribed direction and by an exciting part EX and the output A thereof is shifted into the shift resistor SR by a clock pulse B. And, the output C of an exclusive logic-sum gate G of the output Q1 of the prior-rank bit of the shift resistor SR and the output Q5 of the prescribed-rank bit thereof is obtained. This output C turns to be the one whose peak value is Vcc, whose pulse area is fixed constantly, and whose cycle of repetition is set by the frequency of the output A. Accordingly, when the averaged value AV of the output C is taken out, this averaged value corresponds to the power applied to the vibrator V.

Title: Optical reader
Inventor: SHINODA ICHIROU
IPC: G06K7/10
Filed: 1984-02-02
Abstract: PURPOSE:To prevent excessive exit from a device and to detect immediately degradation of a laser tube by providing a means which compares the light reception value of a sensor, which receives a laser light, with an already determined reference value. CONSTITUTION:The exit light from a laser tube 6 is reflected on a reflective surface 14' of a shutter 14 and reaches a sensor 6. The sensor 16 converts the received optical signal to an electrical signal and applies it to comparators 18 and 19. If the input voltage to the comparator 18 is larger than a reference value V1, the shutter 14 is closed because it means that the laser light is too strong. If the input voltage is smaller than the value V1, the shutter 14 is controlled by the signal from a sensor 15 because it means that the output from the laser tube 6 is proper. If the input voltage to the comparator is smaller than a reference value V2, an alarm circuit is driven to report degradation of the laser tube 6 to a user because it means that the laser light is too weak.

Abstract: PURPOSE:To minimize a degree of contribution of feedback control in feed- forward/feedback control by correcting a disturbance compensating signal of a feedback control system so that it is equal to an operation signal outputted to a process. CONSTITUTION:A sample value control part 24 obtains periodically a difference between an operation signal MV and a corrected disturbance compensating signal DKn as a speed-type correcting signal DELTAKn indicating its variation, and a disturbance compensating signal correcting system 22 uses this signal as a position-type signal Kn, which is the integral value of the variation, and adds this signal Kn to the preceding position-type signal and multiplies a disturbance compensating signal DK by this addition value, and a correction influence compensating system 23 multiplies the signal DK by the signal DELTAKn to obtain a correction signal DKXDELTAKn of the disturbance compensating signal for the current variation, and this correction signal is eliminated from the signal DKn to compensate disturbance due to the current correction in the feed-forward (FF) control output, and correction is performed on a basis of the position-type correcting signal value so that the feedback control output is lower than a prescribed value, and the output is outputted as an FF control output fFF to an adder 13.
