Title: Original reader
Inventor: OGATA NOBUAKI
IPC: H04N1/00
Filed: 1985-02-05
Abstract: PURPOSE:To prevent an original from a positional deviation by providing a space absorbing a force exerted to the projection of the original placed on an original platen between a white flexible sheet fitted to the lower face of an outer face board via an elastic member and the outer face board. CONSTITUTION:A part of the elastic member such as a sponge inserted between the outer face board 4 and the white sheet 6 corresponding to the tip 6E of the white sheet 6 is cut off to form the space 5a there. Thus, in placing the original 7 onto the original platen 2 so that the curled part 7a comes to the position of the tip 6E of the white sheet 6, the tip 6E of the white sheet 6 is bent easily toward the space 5a when the tip contacts the curled part 7a by the space 5a. Thus, the original cover 50 does not exert much horizontal force to the original 7, thereby resulting that without generating of the positional deviation the original reader offers proper reading.

Title: Control unit of direct current arc welding machine
Inventor: ISHII HIDEO
IPC: B23K9/073
Filed: 1979-02-22
Abstract: PURPOSE: To reset the abrupt change of welding current to steady value in a short time and suppress the spattering at the short-circuiting by superposing the output of a comparing amplifier in series to the time constant circuit of a phase shifter which controls the semiconductor element of a power controller.  
     CONSTITUTION: When the short-circuiting of an electrode 3 and base metal 4 is detected, the over detection signal and reference voltage are compared, causing the output voltage of a comparing amplifier 6 to decrease. Because of this, the voltage between a capacitor 13 and θ terminal decreases and the time for charging the capacitor 13 becomes long. When this voltage reaches the switching voltage of a switching element 16 and the switching element conducts, a semiconductor element is controlled, by which the output voltage of a controller 2 is decreased. In the half cycle from the time when the short-circuit current flows, it resets to the welding current of the steady time. When the welding current decreaes sharply, the output voltage of the comparing amplifier 6 increases and therefore it is reset to the welding current at the setting in the half cycle by the similar control circuit.

Abstract: PROBLEM TO BE SOLVED: To conduct a display of high response speed without increasing the manufacturing cost of a liquid crystal integrated product such as a note book computer computing the level variation of an image plane rewrite area by software processing on the PC side to be a signal source, and applying voltage with a variation equivalent level added thereto, to liquid crystal. SOLUTION: A plotting demand is outputted from an application layer (S1000). In an OS layer, this command is temporarily retained (S1001), and a rewrite area is computed on the basis of the plotting demand (S1002). The difference between a present RGB level and a new RGB level of the rewrite area is computed (S1003). A level equivalent to the difference is added to the new level of the rewrite area to issue a plotting command (S1004). In a graphic adaptor layer, plotting is performed by the plotting command, a plotting completion response is returned to the OS side (S1005). The OS layer issues the plotting command based on the retained plotting demand (S1006) and cancels the retained plotting demand (S1007).
