Title: Shutter controller
Inventor: KONO TAKANORI
IPC: G03B15/05
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To realize accurate exposure control with few errors even when the moving speed of a shutter blade used in a program shutter is fluctuated. SOLUTION: Standard time information TPRN showing the time sequential positional change of the shutter blades 23 and 24 is recorded in a time table 11. A controlled variable setting part 5 previously sets control time TAE1 for the opening/closing action of the blades 23 and 24 necessary for appropriate exposure in accordance with the luminance information LV of a subject. A controlled variable conversion part 12 specifies the time information (TPRNAE) corresponding to the control time TAE1 by referring to the time table 11, and further sets a difference from the control time TAE1 to the net control time TAE2. A counter 15 counts pulse signals time-sequentially generated in accordance with the positional change of the blades 23 and 24 starting the opening/ closing action in accordance with an exposure instruction and outputs a pulse counted value PRN.  A timer 14 executes the counting of the net control time TAE2 when the pulse counted value PRN coincides with a specified counted value PRNAE, and outputs a control signal necessary for finishing the opening/ closing action of the blades 23 and 24.

Title: Stuff information amount control system
Inventor: YAMORI AKIHIRO
IPC: H04N19/172
Filed: 1995-08-15
Abstract: PROBLEM TO BE SOLVED: To eliminate overflow and underflow of a buffer by multiplexing stuff information packets as fixed-length packets so that the mean values of stuff information inserted in basic units of data are made nearly constant. SOLUTION: When data having a fixed bit rate arrives in basic units of variable length and are stored in a fixed-length packet, a stuff filling means M1 fills a final fixed-length packet with stuff information unless the fixed-length packet containing data in respective basic units is filled with data in a final basic unit. A stuff information packet multiplexing means M2 multiplexes stuff information packets as fixed-length packets containing only stuff information so that the mean value of the stuff information inserted in the basic units of the data becomes nearly constant. Therefore, the buffer is prevented from overflowing or underflowing when sent packets are buffered, and both variable-length encoded data and fixed-length encoded data can be synchronized.

Title: Cmos inverter circuit
Inventor: YOSHIDA TOSHIHISA
IPC: H03K19/0948
Filed: 1990-08-07
Abstract: PURPOSE:To prevent adverse influences on circuits connected on the downstream side by connecting a resistance between the input and earth terminals of each inverter of the final stage and preceding even numbered stages of the final stage among inverters of plural stages and a resistance between the input and power supply terminals of each inverter of preceding odd numbered stages of the final stage. CONSTITUTION:When power supply is applied and a power supply voltage VCC rises, N-type transistors QN1 and QN3 are always set to turned off states, since their gates are grounded through resistances R1 and R3, and a P-type transistor QP2 is always set to a turned off state, sine its gate is connected to a power supply terminals through a resistance R2. Therefore, it is possible to always maintain the output (node N2) of an inverter 1 at a high level and the output (node N3) of another inverter 2 at a low level and, in addition, the output (node T0) of an inverter 3, namely, an output signal OUT at a high level irrespective of the level of the threshold voltages of each transistor of the inverters 1, 2, and 3.

Abstract: PURPOSE:To make it feasible to wind a deflection yoke having a predetermined performance without possessing coil formers for every number of inch or every manufacture by constituting a winding-forming unit for winding and forming the horizontal coil of the deflection yoke in such a way that the winding-forming curved surface is made arbitrarily changeable. CONSTITUTION:As to the coil-forming curved surfaces of a male mold 12 and a female mold 11 and their combined cross-section, the curved surfaces of the cross-section and the length of the coil former can be arbitrarily set up. For the control, a computer is used so as to form the curved surface set up in advance in accordance with a cathode ray tube for every number of inch or every manufacturer by means of many curved surface controllers disposed inside the coil former. For the universal curved surfaces 11, 12 of the coil former, a thin and resilient titanic alloy or the like is used. An amount of change in length corresponding to the change of the curved surface can be compensated in such a way that the universal curved surface 11 gets into the position 16 belonging to the coil former, which does not form the coil, by a pulling spring 15 of the universal curved surface, so that the expansion and contraction involved in the movement of the curved surface may be absorbed.

Title: Movement detecting device with blinking
Inventor: HATANAKA TOSHIHIKO
IPC: G08B5/00
Filed: 1989-08-11
Abstract: PURPOSE:To obtain an inexpensive and easy-to-handle detecting device which is loaded to a mobile object and detects the movement of the object with blinking by providing a piezoelectric element, an FET switching element, an amplifier, a capacitor, an output transistor, and a switch. CONSTITUTION:A delicate movement is sensitively detected by a piezoelectric element 10, and an FET 18 is actuated for the first time by the piezovoltage generated at detection of the movement. The output of the FET 18 is amplified by an amplifier 26 and charged to a capacitor 36. Thus an output transistor 38 is turned on with the satisfactorily large charging voltage of the capacitor 36 and a switch 42 performs a large blinking action at detection of the movement. Then the charged electric charge of the capacitor 36 is discharged via a discharge path formed when the transistor 38 is turned on. Thus the blinking operation lasts for a fixed time set previously. As a result, the blinking operation is carried out only when the movement of a loaded mobile object is detected without using any ON/OFF switch, etc.

Abstract: PURPOSE:To prevent a roller from being damaged because a paper is butted against a paper peeling pawl and an excessive load is imposed on the peeling pawl in the case that jamming occurs in a fixing part by holding a paper feeding guide provided to be opposed to the paper peeling pawl provided in a heating roller or a pressure roller by an elastic body. CONSTITUTION:The paper feeding guide is constituted of a fixed part 4a and a movable part 4b, and the fixed part 4a and the movable part 4b are coupled with a leaf spring 4c. The movable part 4b is moved as shown by an alternate long and two short dashes line when force F is exerted from a direction shown by an arrow, and it is restored to a home position when the force F is lost. The leaf spring 4c is hardly moved by the force of several grams to several tens grams which is received when paper passes under normal conditions, and a spring constant is set so that the spring 4C may be moved by the force of several hundreds grams to several kilograms which is generated at the time of paper jamming. In such a case, since the movable part 4b of the paper feeding guide is moved in a direction shown by an arrow in the case that larger load than usual is brought about because the paper is butted against paper guide when paper jamming occurs in the fixing part, load is not imposed on the peeling pawl.
