Title: Focal length variable lens
Inventor: NISHIMOTO YOSHIBUMI
IPC: G02F1/29
Filed: 1982-01-07
Abstract: PURPOSE:To obtain an inexpensive focal length variable lens, by impressing an electric field upon a lens group containing an electrooptic crystal by a parallel plate electrode, and changing the focal length of the lens action by changing the impressed voltage. CONSTITUTION:KH2PO4 crystals 11 and 12 having the primary electrooptic effect (Pockels effect), a transparent electrode plate 13, a deflected light source 14, a polarizing plate 15, and a variable power source 16 are provided to this device. The KH2PO4 crystals 11 and 12 have a four rotational inversion axis at its Z-axis and two two-rotational axes of symmetry at its X- and Y-axes, and the Z-axis coincides with the optical axis. When an external electric field is impressed in the direction of the Z-axis, the index ellipsoid of the crystal changes as well known. A light proceeding in the direction of Z-axis in the crystal, upon which the electric field is impressed in the direction of Z-axis, is permitted to proceed in the direction of the polarizing direction of X'- and Y'-axes. Thus the crystals 11 and 12 have a converging lens action and the focal length can be changed continuously by controlling a voltage V from the variable power source 16.

Title: Test method of thin film type thermal head
Inventor: KURAMASU KEIZABUROU
IPC: G01N3/60
Filed: 1978-01-10
Abstract: PURPOSE:To estimate the lifetime of heating elements quickly and easily, by applying power to parallel connection of three or more series circuits of heating elements and resistances. CONSTITUTION:A plurality of heating elements 1 constituting a thin film type thermal head are connected in series with resistances 2 having the same resistance value with that of the heating elements 1, and a power is applied to three or more heating elements 1 simultaneously through a constant voltage pulse power source 3. And the relation between the applied power and the change in resistance when pulses far smaller than lifetime of the heating elements 1 are applied is found. Thus, even if the heating elements 1 reduce in resistance, the resistances 2 work in a way that more than specified power may not be applied to the heating elements 1, and the degree of resistance decrease of the heating elements 1 may be measured more accurately. Hence, the lifetime of the heating elements 1 may be easily estimated, including two defects, namely, decrease in resistance value and thermal fatigue.

Filed: 1984-01-09
Abstract: PURPOSE:To prevent irregularity of carrying when dividing recording elements arranged in a line into some blocks and making recording while carrying recording paper by synchronizing record driving timing of each block and driving timing of a motor.

Abstract: PROBLEM TO BE SOLVED: To improve operation efficiency by recognizing a character included in an area with a specified attribute and outputting text data so as to facilitate operation for extracting a text. SOLUTION: An area dividing processing is executed by click-operating a cursor. Then at the time of matching the cursor to a character recognizing objective menu and depressing the button of a mouse 103 once, a pull down menu is displayed.
