Title: Level shift circuit
Inventor: MATSUMOTO TOSHIYUKI
IPC: H03K19/0185
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To drastically and also easily set a level shift amount and also to reduce power consumption. SOLUTION: When an input signal Vi is supplied to a gate of a P channel transistor 2 of a 1st bias voltage supply circuit B1 , voltage that is Vi -(2Vtp +α1 +α2 ) is supplied from a source of a P channel transistor 5 of a 2nd bias voltage supply circuit B2 to a gate of an N channel transistor 7 of a driver circuit d, and an output voltage Vo =Vi -(2Vtp +α1 +α2 )-(Vtn +r) is outputted. The Vtp and Vtn are thresholds of the P and N channel transistors, the α1 , α2 and r are shift voltages to slightly turn on the transistors 2, 5 and 7, and a level shift amount can be adjusted by appropriately setting them. Also, because the transistors 2, 5 and 7 are set to be turned on slightly, current that flows from a power source to a ground is small and therefore, power consumption is small.

Title: Direct-digital-synthesizer
Inventor: TSUAFURIIRU SHIEFUA
IPC: G10H7/00
Filed: 1991-09-07
Abstract: PURPOSE: To obtain a direct digital synthesizer(DDS) which is satisfactory in the deviation decomposition of frequency modulation(FM) without necessitating a complicated, expensive or slow hardware. CONSTITUTION: An initial modulation multiplied value is selected to obtain the approximate value of desired deviation. Then a clock frequency is selected to refine an FM deviation frequency to make it a desired value in substance. A carrying phase value is calculated by properly using a DDS center frequency and frequency resolution and finally the carrying phase value can be modulated by a frequency modulated value through the use of the asymmetric characteristic of a DDS demodulation source. Consequently, both strong points, the control performance of fine resolution of a standard multiplier and the speed of a binary shifter 28, are provided by modulating a clock frequency.

Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To improve a coil space factor of a motor and, at the same time, to tightly adhere a coil to rising steps, by forming a bobbin to have a core section and flange sections which are tilted outward as a whole at both end sections of the bobbin. SOLUTION: A coil bobbin 1 is provided with flange sections 6a and 6b at both ends of a rectangular core section 4 and one flange section 6a is formed of a plate-like member which is formed nearly perpendicularly to the core section 4. The other flange section 6b is formed of a plate-like member provided with a step section 11 having concentrically formed steps, so that the step sections 11 may be inclined outward from the flange section 6a. Therefore, the flange section 6b has steps on both inside and outside and the planes connecting the bottom sections of the steps are tilted by 60±5 deg. against the teeth surface 3 of a magnetic pole. Then, a wire 7 is tightly wound in layers around the area of the coil bobbin 1 controlled by the flange sections 6a and 6b and core section 4. Therefore, the occupying space of the wire 7 can be expanded, because the flange sections 6a and 6b can be utilized widely due to the outward inclined parts though the number of tuns of the winding 7 varies depending upon the steps of the step section 11.

Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To convey a web in a contactless state with relatively simple constitution by tilting a reverser to control the cross direction on the basis of the detected result of a sensor. SOLUTION: A device for conveying a long-sized web such as a film in a contactless state is provided with at least one sensor 3 in a specified place of a process, and at least one reverser 2 formed to be tiltable. On the basis of the detected result of the sensor 3, a reverser tilting device 4 of the reverser 2 is tilted to control a cross direction. All the reversers 2 are thus tilted to improve control accuracy. In addition, the sensors 3 are fitted to all the reversers 2, and all the reversers 2 are tilted, so that the web can be positively conveyed without lowering control accuracy. The web can therefore be stably conveyed being restrained from meandering caused by the cross direction discrepancy of tension balance and air quantity balance.

Title: Synchronization processing unit and its processing method
Inventor: NOIDE YASUSHI
IPC: H04N7/00
Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To realize a synchronization processing unit and its processing method where the position of a horizontal synchronizing signal is accurately detected even when the amplitude of a video signal or the like with bad linearity is fluctuated. SOLUTION: A video signal is delayed by a prescribed period L1 by loading a counter in response to a start pulse whose start point is a trailing of a Hsync to detect a 0IRE (0%) level of the input video signal for a detection period range W1. Similarly, the signal is delayed by a prescribed period L2 to detect a 40IRE (100%) level of the input video signal for a detection period range W2. A 50% level is calculated from them by an arithmetic operation. Furthermore, the video signal is delayed by a prescribed period L3 to detect a 50% point of a trailing edge of tail end of a signal B1 for a detection period range W3 and a calculated 50% level is used for a cross point of the 50% point of the tail end trailing edge of the signal B1 to obtain a horizontal synchronizing position pulse (A). Thus, the horizontal synchronizing position is stably detected.
