Title: Method and device for processing after sealing up semiconductor device
Inventor: MAEDA KEIJI
IPC: B29C45/00
Filed: 1978-12-14
Abstract: PURPOSE: To raise the efficiency in workability when removing the exposed peripheral part of a radiator plate on a frame for semiconductor units or integrated circuits, by bringing a cutter into contact with the exposed side of the radiator plate and causing relative displacement between a semiconductor device and the cutter.  
     CONSTITUTION: Semiconductor frames 50, each of which is fitted with a plurality of semiconductor devices, are stacked in a frame housing section 1. The semiconductor frame is conveyed from the housing section. The position of the frame is then changed by a position corrector 2 so that the frame extends perpendiculary to the direction of the conveyance. The radiator plates of the semiconductor devices are thrusted into surface contact with cups 29 by the thrust mechanism 5 of a burr removing system 3. Relative motion is caused between the semiconductor frame and a cutter by a driving mechanism 6 to remove burr. After-processing is thus effected with high accuracy without damaging the exposed sides of the radiator plates of the semiconductor devices and a package.

Then, the oscillation frequency of oscillator 15 is set above the response frequency of the flow control solenoid valve and variation in the duty ratio of an oscillation rectangular wave is made possible, so that while electromagnetic energy is accumulated in coil 7 at the time of rectangular-wave pulse output, it is discharged when no pulse output appears. Consequently, continuous control over a large current can be exercised by a transistor of small power consumption.

Title: Method for controlling recording mode for image forming device
Inventor: KANAYAMA TOSHIKIYO
IPC: B41J29/48
Filed: 1990-06-15
Abstract: PURPOSE:To form a desired image without resetting a recording mode after the cancellation of abnormality by starting the count of time by a timer when the abnormality occurs, returning a mode to the recording mode when the abnormality occurs in the case that the abnormality is cancelled within a prescribed time and returning it to a standard moe in the case that the abnormality is cancelled after the prescribed time. CONSTITUTION:When the occurrence of the abnormality is detected by an abnormality occurrence detection means 52, the count of the prescribed time is started by the timer 60. Besides, it is judged by a controller 50 whether the prescribed time has passed or not when the cancellation of the abnormality is detected by an abnormality cancellation detection means 54. Then, in the case that it is before the prescribed time, the mode before the occurrence of the abnormality is set. Besides, in the case that it is after the prescribed time, the standard mode is set to make the device stand by under a state that the image can be formed, The prescribed time is set to be longer than a time until possibility that a first worker cancels the abnormlity and shorter than a time until the possibility that a second worker cancels the abnormality, for example, to the extent of 30 seconds - 2 minutes. Thus, for the first and the second worker, the recording mode need not be reset after the cancellation of the abnormality and the desired image is formed.

Abstract: PURPOSE:To stabilize the oscillation frequency and to improve responsiveness to a skew by switching the outputs of filters when video heads are switched, and supplying a voltage-controlled oscillator with the output of a 2nd filter which passes even a frequency component higher than a frequency component passed through a 1st normal filter. CONSTITUTION:When the scanning of the video heads is switched from a specific track to an adjacent track, a control circuit 5 generates a control signal for a specific time, and consequently a switching circuit 4 is put in switching operation tc supply the output signal 200 of the 2nd filter 3 to the voltage- controlled oscillator 6 through the switching circuit 4. The 2nd filter 3 passes the higher frequency component than the 1st filter 2, so when the output signal 200 of the 2nd filter 3 is supplied to the voltage-controlled oscillator 6, the response characteristics of a PLL system becomes faster than usual. Consequently' the frequency is stabilized with the simple circuit constitution and excellent response characteristics to variation of a synchronizing signal are obtained.
