Title: Sheet supporting device for rotating body
Inventor: KAWAKUBO TOSHIO
IPC: B41J13/22
Filed: 1985-05-16
Abstract: PURPOSE:To miniaturize the sheet supporting part and to prevent the destruction of the sheet supporting part by supporting a sheet with a comparatively small and constant force. CONSTITUTION:Since the gravity center of a sheet support assembly 3 is placed near a regulating member 11 than a pin 18 functioning as the fulcrum of the assembly 3, a centrifugal force is exerted in a direction turning the sheet support assembly 3 in the arrow AR 2 in a figure, that is, the same direction as the force of a spring 10. The force depressing a sheet against a drum 1 actually depends on the force generated by claws 5a-5j being elastic bodies. That is, the force generated by the claws 5a-5j is smaller than the force by the spring 10 and the position of the support member 7 is fixed to a position predetermined by the spring 10 and the regulating member 11. Since the claws 5a-5j depress the sheet at the predetermined state, the supporting force of the sheet depends only on the force by the claws 5a-5j independently of the force of the spring 10 and the centrifugal force. That is, the sheet supporting force is constant.

SOLUTION: In a bump electrode 5A near an outer peripheral edge 23 of an IC chip out of a number of bump electrodes 5 of a chip support substrate 3, for example, an In-Sn low melting point alloy having the melting point at 177 deg.C is used, and in the other bump electrode 5B, in order to secure a mechanical strength between a semiconductor device and a mounting substrate, for example, a Pb-Sn alloy having a melting point at 255 deg.C is used. Incidentally, the bump electrode 5A has the same effect even if using gold instead of the low melting alloy.

Abstract: PURPOSE:To change the effective reflection factor in the direction of the radius, by inserting a concave or convex lens-shaped quartz plate between a polarizer and a reflective mirror. CONSTITUTION:A polarizer 1, a concave or convex lens-shaped quartz plate 2, and a 100% reflective mirror 3 having a uniform reflection factor distribution are provided. In this constitution, an incident light 5 becomes a linearly polarized light 5A after passing through the polarizer 1 and has the phase delayed differently in the direction of the radius by passage through the quartz plate 2 and is reflected by the 100% reflective mirror and has the advance direction turned at 180 deg. to become a reflected light 6A and passes through the quartz plate 2 again to add the phase delay and is incident to the polarizer. Since a reflected light 6B incident to the polarizer 1 has orthogonal polarized components, a part of the light 6B becomes a reflected light 6 which goes on an optical axis 4 in the direction opposite to that of the incident light 5, and another part of the light 6B becomes the second reflected light 7 which goes on the second optical axis 8. This reflected light 6 and the second reflected light 7 have intensity distributions different in the direction of the radius.

Filed: 1980-07-31
Abstract: PURPOSE: To alleviate shocks when changing speed in such a way that the time for the clutch on its half way is controlled in proportion to treating of an accelerator pedal, in an electromagnetic clutch for vehicle to transmit its power.  
     CONSTITUTION: Speed change signal (a) which is generated by controlling a shift lever turns off a transistor 41, charges a capacitor 43 while output voltage (d) rises up with the lapse of time. Then, as an accelerator pedal is stepped on, clutch hold signal (b) grows to a high level, it is inverted to a low level signal (b') in a reference voltage generating circuit 49, and when it becomes the same as the prior signal  (d), it gives signal (e), which releases half-way clutch signal (j) that is synthesized  by vehicle speed signal (c) and output (f) from an oscillatory circuit 53. At the  time of low treading, since the clutch hold signal (b) turns to a low level, output  from the reference voltage generating circuit 49 grows to a high level (b"), the time  which corresponds to the signal (d) becomes longer, therefore it becomes a long  half-way clutch time.
