Title: Polyimide film and its production
Inventor: NAKAJIMA TOSHIO
IPC: B29C71/02
Filed: 1986-04-09
Abstract: PURPOSE:To obtain the titled film excellent in mechanical properties, heat resistance and moisture absorption characteristics and being anisotropic in these properties, by passing a solvent-containing film of a specified aromatic polyamic acid through a heating furnace along the lengthwise direction so as not to change its crosswise dimension. CONSTITUTION:A solution formed by dissolving a polyamic acid based on repeating units of formula I in an organic solvent such as N-methyl-2-pyrrolidone is cast on a flat metallic belt or the like to form a liquid film. This liquid film is fed to a heating furnace to remove the solvent to thereby form a solvent-containing film. While the crosswise dimension of this film is being kept constant by clamping both edges of the film, it is fed too a heating furnace along the lengthwise direction, heated to 10-200 deg.c for about 20-300min to remove the remaining solvent and further heated to 200-450 deg.C for 20-300min. In this way, the titled film based on repeating units of formula II, excelling in heat resistance, suited as, e.g., a base film for high-density magnetic recording media and characterized in that the difference between the lengthwise and crosswise tensile strengths, elongations, tensile moduli and glass transition points are each within 5%, and the differences between the coefficients of lengthwise and crosswise expansion and between the coefficients of lengthwise and crosswise moisture expansion are each within 10% can be obtained.

Filed: 1983-05-09
Abstract: PURPOSE:To reduce dimensions and economize costs, by converting a detecting current of inverted parallel light emission diode with a light reception diode facing to its inverted parallel light emission diode. CONSTITUTION:2c represents an inverted parallel light emission diode in which 2 light emission diodes emitting lights of mutually different wave-lengths are connected in inverted parallel connection and consolidated into a single piece. When a detecting current is transmitted to an inverted parallel light emission diode 2c corresponding to a voltage applied between terminals of thyrister 1, as the inverted parallel light emission diode 2c is combined and constructed to emit light of different wave-lengths according to a direction of the detecting current, an optical signal transmitted through a light-guide 4 gives light of different wave-lengths according to a polarity of voltage applied to the thyrister 1 to a spectral prism 9. The spectral prism 9 transmits the received optical signal to a light reception diode 5a or 5b after a spectroscopic division. Output currents of these light reception diodes 5a, 5b are composed by an operational amplifier 6 and gives an output signal to an output terminal 8 as a voltage signal similar with a voltage applied to the thyrister 1.

Title: Signal processing unit
Inventor: KOMATA TOMOJI
IPC: G06T7/00
Filed: 1988-04-01
Abstract: PURPOSE:To improve the signal processing capability by varying the phase of each output of a nonlinear vibrator so as to interfere other nonlinear vibrator in plural nonlinear vibrators and providing at least one output section for the plural nonlinear vibrators. CONSTITUTION:The system consists of three nonlinear vibrators OSCi (i=1'-3) and the coupling among the vibrators causing the interference of the vibration wave. In the case of coupling two nonlinear vibrators such as the OSC1 and OSC2, the phase difference of the two nonlinear vibrations is set by adjusting an external input signal and the coupling parameter. Moreover, at least one output section (1 or 2) is provided to the entire plural nonlinear vibrators to control the relation between the amplitude and phase when 'locking' takes place. Thus, in the locking state of the vibrators, the signal is not only processed simply depending on the input signal, but also the phase difference is converted into the quantity of the amplitude by the mutual interference of the vibrator thereby using the signal carrier. Thus, the signal processing is improved.

Abstract: PURPOSE:To use electric equipments efficiently even by a breaker with small current capacity by monitoring timing information on the feeding and breaking of each equipment previously and by exercising control so that the total value of currents of the electric equipments is average in terms of time. CONSTITUTION:For example, when a 1KW hot plate and a 600W electric ''kotatsu'' (foot warmer with quilt over it) are both used, a terminal controller is provided to each equipment. A sequence of pulses of an equipment number code 13, a set temperature code 14 and a present temperature value code 15 is sent from the hot plate terminal controller to a centralized controller. From the electric ''kotatsu'', an equipment number code 16, a set temperature code 17 and a present temperature value code 18 are sent with a slight difference in time. On the basis of those pieces of information, the centralized controller determines which equipment is turned on and which one off, and sends instruction signals for those, e.g. the equipment number code 20 and feeding instruction code 21 of the hot plate and then the equipment number code 22 and breaking instruction code 23 of the electric ''kotatsu''. Therefore, the hot plate and electric ''kotatsu'' are turned on and off as shown in figures 24 and 25, and the total current in 26, so that a 10A breaker is useable.

Title: Switch device
Inventor: KIRIHARA YASUHIKO
IPC: B60R16/02
Filed: 1991-04-15
Abstract: PURPOSE:To exhibit an off state without fail at the time of engine stop to stop a constant speed travelling device by combining a switch main body, a magnet magnetized/demagnetized by an ignition switch, and an arm and cam interlocked with an operating knob. CONSTITUTION:When a switch main body 19 is in an off state due to energizing force of a spring 16, even if an ignition switch is turned on to excite a magnet 18, this state is maintained because a metal plate 11 of a cam 7 is separated. When a push knob 1 is pressed, the cam 7 is brought into contact with the magnet 18 via an arm 12 and the spring 16 is pushed up to turn on the main body 19 to bring a constant speed travelling device into an operating state. If the ignition switch is turned off in this case, demagnetizing of the magnet 18 together with the spring 16 returns the cam 7 to an original position to turn off the main body 19. Accordingly, wasteful power consumption due to sudden starting caused by restart and at the time of engine stop is prevented.

Filed: 1979-07-02
Abstract: PURPOSE: To make it possible to emphasize the sharpness of duplicate images without requiring many slits by weighting the respective picture element signals near the scanning points and using these weighted mean values.  
     CONSTITUTION: The color signals read out from the original picture of an image cylinder 10 are subjected to A/D conversion 12 and are converted to respective color plate signals in a color operating unit 13, thence they are sent to a color selecting circuit 14, where the signals of the color plates desired to be duplicated and recorded are selected and are supplied to a memory 15. Next, a sharpness emphasizing circuit 16 reads out the density information near the required scanning points from the memory 15 and performs weighting of specified coefficients upon these, further averages the weighting and generates a sharpness emphasized signal E. This signal E is sent via a D/A converter 17 to a recording head 19, by which the images are recorded. In this way, the need for beforehand preparing many slits is eliminated and the duplicate images of emphasized sharpness may be obtained.
