Title: Process progress control system
Inventor: KABASAWA MASAYA
IPC: G06Q50/00
Filed: 1988-06-07
Abstract: PURPOSE:To easily obtain the information with which the set-up of jobs can be prepared by calculating the ratio of the remaining term of works from the number of logical work days covering the in-process process and the final one of each product and the number of days covering the finishing data of the present in-process process and the scheduled finishing data of the final process and displaying the obtained ratio on a display means for the product-based progress state. CONSTITUTION:A means which displays the progress state of each product displays the in-process products of each process in the order of ratios of the remaining term of works based on this ratio. In other words, the conventional system is applied for each product name, the process name, the scheduled finishing data of the process, the scheduled finishing sate of the final process, the number of delayed days, and the number of stagnated days respectively. Then the ratio of the remaining term of works is added. Thus a worker can decide the starting product for process owing to the display of said ratio of the remaining term of works.

Title: Power supply output controller
Inventor: TAKAHASHI CHIKAYOSHI
IPC: G01R31/30
Filed: 1982-08-17
Abstract: PURPOSE:To prevent a trouble due to the misresetting of a switch, by breaking the current path of a switch circuit to switch the voltage of high or low margin test when the initializing signal of a CPU is detected. CONSTITUTION:For instance, the initializing signal obtained from initialization that is executed first is applied to actuate a CPU20 while the 1st switch 15 is kept at a position U. Thus a driving circuit 22 stops its working, and therefore the driving of the 3rd relay 21 is stopped. As a result, a relay switch 23 is opened and the 1st and 2nd relays 17 and 19 are neither driven at a time. Then a synthetic resistance of resistances 8, 11, 9 and 12 is inserted between an error detecting input of an error amplifier 2 and a ground. The stabilized output voltage 5V thus obtained is applied to each part of the CPU20 to perform an ordinal operation. When a margin test is carried out again, the 2nd switch 24 is turned on.

Abstract: PURPOSE:To change the alarm time with bedtime within an allowable time range so as to enable sleeping hours to be adjusted by providing a control means by which the alarm time stored by an alarm time storage means is varied with the bedtime within an allowable time range. CONSTITUTION:An alarm time and its adjustment allowable time and standard bedtime are set using a key 5. When a user goes to bed an alarm set switch 4 is closed to set an alarm and then the difference (t) between the current time and the standard time is computed. Next it is determined whether or not the difference (t) is within the range of - one hour <=+ one hour and if so the alarm time being set is used. When the difference (t) is not within the range the alarm time is obtained by adding the time stored 7 for alarming to allowable time storage 3 if the difference (t) is within the range of t>+ one hour. In this way the alarm time is adjusted to the bedtime within the range of fifteen minutes.

Filed: 1983-08-03
Abstract: PURPOSE:To quickly and accurately detect the location of piping rupture by detecting elastic waves generated by the rupture of the piping and transmitted through the structural members of the piping by multiple elastic wave detectors, and comparing moments in time at which the elastic waves were detected by the detectors. CONSTITUTION:When a main steam pipe 3 is ruptured at point A, the internal steam blows out as a high speed jet, and its reaction will cause the pipe to deform at the point of rupture, delivering elastic waves which are transmitted in the pipe. Such elastic waves are inputted to timers 12a, 12b via filters 11a, 11b, and the time difference is measured between the detected moments at the detectors 9a, 9b. Let the transmission speed of the elastic wave be C, and the respective detected moments Ta, Tb, then, the location of the reptured hole A is determined to have ocurred at a point which is away from the center between the two detectors toward the detector 9a by CX(Ta-Tb).

IPC: B65H3/52
Filed: 1983-08-03
Abstract: PURPOSE:To prevent hands and fingers of an operator from being caught etc., and facilitate adjustment of the captioned device by allowing the rotary shaft of a driving motor to directly make contact with the surface of a feed roller and thereby transmitting the rotation driving force of the motor to the feed roller. CONSTITUTION:A supporting shaft 19 is mounted on a part of a motor 10 and rockably supported on bearings 29, 20'. The motor 10 is arranged such that the rotary shaft 11 thereof is in contact with the upper half side surface of a feed roller 5. Hereby, force F taking the shaft 19 as a center is applied to the motor 10 by its own weight and a component force F' directed toward the central shaft 22 of the feed roller 5 forces the rotary shaft 11 to make contact with the surface of the feed roller 5. Accordingly, rotation of the motor 10 causes the feed roller 5 to rotate due to frictional force against the rotary shaft 11. Thus, the surface of the feed roller 5 is in contact with the rotary shaft 11 to produce slight sliding, so that it is possible to prevent hands and fingers of an operator from being caught together with the possibility of facilitating device adjustment.
