Title: Method and apparatus for evaluating liquid crystal element
Inventor: URANO TAEKO
IPC: G09G3/00
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To simply and highly sensitively identify electric field response impurities included in a liquid crystal element by continuously applying a working electric field to the liquid crystal element and removing the electric field, and thereafter by shedding light in a specific wavelength region while applying an AC pulse electric field to the element with time to time-decompose light which has passed through a liquid crystal layer for measurement. SOLUTION: A working electric field, concretely a DC electric field is continuously applied to a liquid crystal element between a pair of electrodes. Then after the DC electric field is removed, an electric field response curve is measured every predetermined time interval or continuously. That is, a DC electric field is applied to the element 10 by a DC power source 1 and an AC pulse electric field is applied to the element 10 by a pulse generator 2, respectively. On the other hand, infrared light of an infrared light source 3 is dispersed by a scattering element 4 for taking out infrared light in a specific wavelength region, it is shed to the element 10 through a polarizer 5, transmitted infrared light is detected by an MCT detector 6 and it is converted into an electric signal.  The signal is amplified by an amplifier 7 and input to a digital sampling oscilloscope 8 for obtaining an electric field response curve by a computer 9. A change with time is obtained from an amount of change to identify impurities.

Title: Frequency modulation circuit
Inventor: WATANABE MASAAKI
IPC: H04J1/02
Filed: 1983-07-06
Abstract: PURPOSE:To eliminate the need for a band-pass filter by adding a circuit using Zener diodes connected in series as a voltage limit circuit to a preamplifier so as to limit the change in an output frequency. CONSTITUTION:The Zener diodes 19, 20 are provided to an output part of the preamplifier, a Zener voltage of the diode 19 is selected as Vc-Vb1 and a Zener voltage of the Zener diode 20 is selected to Vb2. When the base voltage Vb is higher than the voltage Vb2, a current flows to the diode 20 and the base voltage Vb is limited to the voltage Vb2. Since the base voltage Vb is limited between the voltages Vb1 and Vb2 by the diodes 19, 20 in this way, an output frequency Fout is limited also between Fout1 and Fout2. Thus, the maximum frequency of the output frequency of a frequency modulation circuit FM-MOD1 to a frequency F1 is set lower than the minimum frequency of an output frequency of a frequency modulation circuit FM-MOD2 to a frequency F2 and the relation like this is established sequentially.

Title: Sheet transporting device
Inventor: OTSUKA MASATO
IPC: G03G15/00
Filed: 1990-05-14
Abstract: PURPOSE:To prevent a sheet from wrinkle or breakage by allowing the sheet to pass only between the roller of No.1 correcting means and a roll of the uppermost stream row when the sheet is to be transported to a curved transport path. CONSTITUTION:Because a flapper 24 lies in the position shown in the attached illustration at the time of face-down exhaust of sheets, a cut sheet P is transported being pinched by a transport roller 25 and a roll 26a of the uppermost stream row in rotating direction among rolls 26a, 26b in followup rotation after the transport roller 25, and there no uncurling process will take place. The cut sheet P is further curled to the printing face side when it passes a reverse path G, where No.2 correcting means H bends the sheet in the opposite direction to the curl at the time of fixation and the curl within the reverse path G, and thus the sheet gets rid of curl and is exhausted to an exhaust tray 21. Uncurling of the cut sheet P is made only once by the No.2 correcting means H, in this manner, not only at the time of face-up exhausting but also at face-down exhausting, so that the cut sheet P is free from risk of getting wrinkle or breakage.

Abstract: PURPOSE:To prevent surely the occurrence of step out of a vehicle motor by lowering the drive pulse frequency in a driving circuit when a driven member, such as a throttle valve is driven to its fully closed position or its fully open position and so it touches a stopper member. CONSTITUTION:In an intake path there are disposed a first throttle valve 20 turned round with a stepping motor 24 and a secondthrottle valve 21 linked to an accelerator pedal 22. The first throttle valve 20 is regulated in its move position by means of a stopper (not shown in the figure), corresponding to the fully closed position or a rotary position. When the throttle valve 20 has reached to its stopper position and this state is detected by a throttle opening sensor 27, etc., the drive pulse frequency supplied to the stepping motor 24 is lowered with an engine control unit 23. The driving torque of the stepping motor 24 is thus increased, so that the reaction return of the throttle valve 20 at the time of touch to the stopper is prevented.
