Title: Liquid crystal display device
Inventor: YAMADA HIDETOSHI
IPC: G02F1/133
Filed: 1983-04-21
Abstract: PURPOSE:To obtain a good gradation display characteristics over a wide temperature range and to obtain a liquid crystal display device proper to an electronic view finder or the like for a portable apparatus by removing a variation component of incident light amount included in an electric signal and controlling effective voltage to be applied so as to hold the size of the signal at a fixed value. CONSTITUTION:A photodetector 21 outputs a signal Vo proportional to the intensity of light transmitted through a liquid crystal layer 1. When voltage VSR applied to transparent electrodes 15, 16 is extremely high for a using temperature, Vo>Vref is formed and a signal for reducing the VSR is applied from a comparator 24 to a power supply 26. Consequently, the applied voltage is suppressed and the VSR is set up so that It=50% is formed. When the VSR is extremely low, Vo<Vref is formed and a signal for increasing the VSR is applied to the power supply 26. Thus, the VSR is controlled to an optimum value in accordance with the using temperature. Simultaneously, voltage Vs to be applied to a display cell 11 is also controlled so that the most preferable gradation characteristics can be obtained.

Filed: 1989-03-23
Abstract: PURPOSE:To automate signal input changeover to a television monitor by converting television signals of different signal forms into the same signal form and detecting a waveform or the like specific to the signal form so as to switch the signals automatically. CONSTITUTION:An FM signal receiver receives television signals A, B of different signal forms, amplifies and detects them and outputs a video signal of a basic frequency band.

Title: Evaluation of anisotropy in intensity of mechanical strength of titanium or titanium alloy
Inventor: FUJISAWA KAZUO
IPC: G01N29/00
Filed: 1987-03-24
Abstract: PURPOSE:To evaluate anisotropy of mechanical strength in a non-destructive manner, by generating a transverse wave vibrating in the direction of rolling and perpendicular thereto in a titanium or titanium alloy plate to detect a propagation speed ratio thereof. CONSTITUTION:A planar titanium rolled material 20 is transferred as indicated by the arrow and DC electromagnets 1 are arranged above and below the material. Coils 2a and 2b are arranged one upon another between the upper electromagnet 1 and the rolled material 20. Trigger pulses Pa and Pb are generated alternately at a fixed cycle from a timing control circuit 3 to be inputted into pulse generators 4a and 4b. Current triggered from the generators 4a and 4b flows through the coils 2a and 2b to generate a transverse wave vibrating in the direction of rolling of the rolled material 20 and perpendicular thereto. Reflected waves of the respective transverse waves are received and inputted into a time difference measuring circuits 5a and 5b to detect time to the reception of the reflected waves from the generation of a trigger. Anisotropy of mechanical strength is evaluated from a difference between propagation speeds in the direction of rolling and perpendicular thereto. Thus, anisotropy of mechanical strength of the rolled material can be evaluated continuously thereby enabling a hot rolling satisfactorily.

Abstract: PURPOSE:To enable to obtain an optimum printing density without generating any excessive heat at a driving element, by driving a hammer magnet by a logical product of a driving signal for a printing hammer and a row of printing density controlling pulses, in an impact printer. CONSTITUTION:When selection signals are selected in accordance with the thickness or the number of sheets of a printing paper used in a line printer, for example, when IMP1 is selected to be L while IMP2 is selected to be H, an inverted output of the raw of density controlling pulses generated by an oscillator OSC1 is outputted from an NAND circuit (which is connected to OSC1) through an AND circuit A, and a transistor Qn is turned ON or OFF by the logical product of the inverted output and a hammer-driving pulse (a), whereby an amount of printing energy according to the selection signals is given to the hammer. In this case, when both of the selection signals IMP1, IMP2 are selected to be L, outputs from the NAND circuit and the AND circuit A become H, and the hammer performs a printing action with the maximum energy. Accordingly, the optimum printing density can be obtained without generating any excess heat from the driving element.

SOLUTION: A cover 2 is so structured that it can move along a groove section 3 on an equipment body 1 and can turn at the lower end of the groove section 3. In such a condition that a front face of the cover 2 faces a front face of the equipment body 1, a liquid crystal display A1 located on the front face of the equipment body 1 is protected by the cover 2, thereby preventing the liquid crystal display A1 from destruction when the equipment body 1 is not in use [Fig. (A)]. In such a condition that the cover 2 is located as to cross at right angles with the front face of the equipment body 1, the liquid crystal display A1 can be kept in visible state at all times when the equipment body 1 is mounted on a desk through the cover 2 [figure (D)].  In such a case that the front face of the cover 2 faces a rear face of the equipment body 1, the cover 2 becomes an integral part of the main body 1 with the liquid crystal display A1 being exposed, thereby increasing the operability of the equipment body 1 when used.
