Title: Time-division photographing device
Inventor: TAKADA MIKIHIKO
IPC: G03B15/16
Filed: 1986-03-31
Abstract: PURPOSE:To photograph the body in movement and to grasp the movement state of the moving body at a glance by providing a time-division control part which exposes a specific part on a photosensitive film to light passed through a selection shutter and then inverts a transmission part and a light cutoff part by operating the selection shutter. CONSTITUTION:A time-division photographing device has a liquid crystal shutter 30 arranged in front of the photosensitive film 20. The liquid crystal shutter 30, therefore, exposes the photosensitive film 20 only where the shutter transmits light, and no exposure is performed where the light is cut off. The liquid crystal shutter 30 polarizes the light and exposes the photosensitive film under the control of a voltage control circuit 40 and a voltage is applied to a liquid crystal charged part 34. When no electric field is applied, the liquid crystal shutter 30 provides rotary polarization wherein incident light is rotated by 90 deg. and when a voltage higher than a fixed threshold value is applied, respective molecules of liquid crystal change their array to an electric field direction to lose the rotary polarization. Consequently, the exposure of the photosensitive film 20 is controlled by the timing of the voltage application of the voltage control circuit 40 and performed on a time-division basis corresponding to two kinds of planes of polarization (longitudinal plane 32A of polarization and lateral plane 32B of polarization) which are arrayed zigzag.

Title: Mesh generating method
Inventor: SHO TOSHIYUKI
IPC: G06T17/20
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To reduce the generation time of boundary protective layer-attached meshes for simulating semiconductor processes and devices by limiting the mesh generating area to those regions where associated boundary protective layers may be broken at retrieval of a triangular mesh where the layer is broken. SOLUTION: Triangular meshes are generated (S103) only at those regions having the boundary protective layer breaking possibility. Whether or not such mesh having the boundary protective layer breaking possibility exists among the generated meshes is judged (S104). If existing, the mesh points in the region are projected on the boundary line segments and registered as new mesh points on the boundary line segments (S105). If no mesh point to be newly projected exists, the triangular meshes are completed to obtain final meshes (S106). This reduces the number of generated meshes and hence the triangular mesh generating time.

Title: Sheet transfer device
Inventor: TAKAHASHI TETSUO
IPC: B65H83/02
Filed: 1990-03-23
Abstract: PURPOSE:To provide an inexpensive sheet transfer device by combining a one- way clutch with a lead screw which rotates in one-way direction and reciprocates, so that both drive of a pick belt and shift of a sheet guide can be made by a single motor. CONSTITUTION:During normal rotation of a motor 11, a drive shaft 12 and a pick belt 13 are rotated through the intermediary of a timing belt 13 so as to transfer a sheet. Simultaneously, gears 15, 16 are rotated, but no torque is transmitted to a lead screw 18 which rotates in one-way direction and reciprocates, since a one-way clutch is press-fitted in the gear 16 with a predetermined direction. Accordingly, a sheet guide 10 is not shifted. When the sheet size is changed, the motor 11 is reversed so that a torque is transmitted to the lead screw 18 by means of the one-way clutch which is in a coupling direction, and accordingly, the sheet guide 10 is shifted to a position corresponding to the sheet size.
