Title: Simple acoustic reproducing device driven by spring motor
Inventor: WATANABE KATSUMI
IPC: G11B19/22
Filed: 1981-03-25
Abstract: PURPOSE: To prevent a reproducing stylus from being damaged by supporting a record  disk moving within a prescribed range along a center shaft stood up in a casing, contacting the reproducing stylus with a recording groove and accomodating the stylus in  the concave part of a reproducing end point.  
     CONSTITUTION: A winding knob 11 is wound to charge a constant torque spring motor  which is not shown in the drawing through a winding wheel 12, a winding follower 35  and a take-up reel 36. Depression of a starting beam 17 backs a record disk 3 and separates it from rotation stopping pawl element 19, making it possible to rotate the  record disk 3 together with a turn table. Then the constant torque spring motor rotates the turn table 23 through a driving wheel 39 and a follower 42 and simultaneously a pickup 7 is returned to a reproduction starting point. When the starting beam 17  is released, the record disk 3 advances, a reproducing stylus is engaged with a recording groove and stylus pressure is applied, so that the record disk 3 starts to rotate, a  diaphragm 6 of a speaker 5 is oscillated and sound is generated. If the reproducing  stylus passes through the reproduction end point of the record disk 3, the disk is depressed to be separated from the reproducing stylus, preventing the reproducing stylus  from unnecessary sliding.

IPC: F02F1/24
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a nozzle holder mounting structure of a cylinder head capable of effectively preventing generation of a crack around a fuel hole of the cylinder head. SOLUTION: A tip of a nozzle holder 7 is press-fitted into the lower end part of a mounting hole 6 of a cylinder head 5 and is mounted, step parts S1, S 2 of two upper and lower steps are formed on the upper side within the mounting hole 6 and a clearance C1 of the step part S1 on the side of the upper step and the nozzle holder 7 is set narrower than a clearance C2 of the step part S2 on the side of the lower step. As a result, because the nozzle holder 7 hits on the side of the step part S1 on the side of the upper step first when the nozzle holder 7 oscillates, impact force applied to the step part S2 on the side of the lower step is mitigated and a crack generated around a fuel hole 8 of the cylinder head 5 is effectively prevented.

Title: Method of electron beam exposure
Inventor: IGAKI SEIGO
IPC: H01J37/317
Filed: 1980-04-03
Abstract: PURPOSE:To greatly reduce the exposing time by discretely providing a plurality of simple shape regions in one subfield and determining an original point of each region by introducing an initial shifting quantity to a high speed scanning D/A converter. CONSTITUTION:A simple-shape-region initiating point memory 10 memorizes the coordinate information of the original point of each simple region, and outputs different pieces of information xn and yn for various regions. Pieces of information of widthes and lengths are given to a high speed counter 6. An initial value INT is given to the counter 6 from a high speed initial point shifting circuit 11 based on the pieces of information xn and yn. Therefore up and down counting is performed in the range of xn-xn+ax. As a result, an output G of the high speed scanning D/A converter 9 varies with said counting. Since pieces of information Xn and Yn given to an initial point register 5 are the coordinates of the initial points of the subfields, an output F from a positioning D/A counter 8 varies for every subfield unit. When said outputs F and G are synthesized, the electron beam deflected by an deflection amplifier DEF can contribute the high speed exposure of the desired pattern in the deflection field.
