Title: Developing device
Inventor: TAKATANI TOSHIHIKO
IPC: G03G15/08
Filed: 1986-06-11
Abstract: PURPOSE:To improve toner feeding properties to a developing roller by impressing DC voltage with polarity reverse to the polarity of a developer on a developing roller, a developer feeding member and a layer-thinning regulation member and setting specific conditions among respective impressed voltages. CONSTITUTION:Respective DC voltages with polarity reverse to the polarity of the developer are impressed on the developing roller, the developer feeding member and the layer-thinning regulation member, and when the voltages impressed on respective members are defined as VR, VSP and VR/P, the relation of ¦VR¦<=¦VSP¦ (A) and ¦VR¦<=¦VR/P¦ (B) is formed among respective impressed voltages. When the relation of (A) is formed, the electrical potential of the developing roller 6 with the charge of toner forms the trough of potential with respect to the electric potential of a toner feeding member 5 at the time of feeding toner from the member 5 to the roller 6. Consequently, the toner feeding property from the member 5 to the roller 6 is improved and uneven feeding can be removed. When the relation of (B) is formed, the distribution of toner charge is suppressed and the developing state can be kept at an excellent state free from ground stain.

Title: Needle thread supplying device for zigzag stitching machine
Inventor: KOSAKU MINORU
IPC: D05B3/02
Filed: 1989-05-30
Abstract: PURPOSE:To keep the balance of a stitch by preventing the variation of needle-thread tension due to a difference between thread pathway lengths by a method wherein the title device is so formed that needle-swing direction is detected and thread supply is increased or decreased according to the detected needle-swing direction. CONSTITUTION:A needle-swing cam 9 is turned from an arm shaft 7 for a sewing machine through a reduction gear 8, and a needle-swing oscillation stand 11 is oscillated through a needle-swing rod 10. A semicircular plate 19 is fixed on a rotary shaft 18 of the needle-swing cam 9 and its rotation is detected by a sensor 20 for needle-swing direction. The sensor 20 is so formed that a pulsative output signal is generated every time the semicircular plate 19 is made a half turn, i.e., by a right swing and left swing, and a setting value from each of setting devices 21, 22 for the quantity of needle thread-drawing at the right swing and left swing is inputted to a selector 23. In this time, the setting value at the right swing is a value adding a compensated value 24 due to a difference between thread pathway lengths. The selector 23 is controlled by the output signal from the sensor 20 for the needle-swing direction, and either of the setting values of the quantity of the needle thread-drawing at the right swing and left swing is inputted into the operation device 5 together with others of sewing information. In this way, needle thread supply is operated so that the thread-drawing at the right swing is more compensated, compared to the thread-drawing at the left swing.

Title: Bit modifying circuit
Inventor: KOMAMURA TAKAYUKI
IPC: G06F9/30
Filed: 1987-06-01
Abstract: PURPOSE:To modify the bits by using a bidirectional register to store temporarily the byte reading information with one side of this register connected to a memory and the other side connected to a bit rewriting circuit respectively and rewriting only the corresponding bit selected by a decoder out of the byte information stored temporarily. CONSTITUTION:When the 1-byte information is read out of a memory 1 and then written again into the memory 1 after the bit qualification, the read information charges or discharges all of capacities 2 via a bus 5. In this case, the write control signal is invalid and the tristate buffers 4 are all set at high impedances. The memory 1 is also set at a high impedance after its reading is through and therefore the byte read information is stored temporarily in the capacity 2. Then the write information is transmitted so that the selected one of capacities 2 is charged or discharged when the high impedance of buffers 4 corresponding to the bit addresses are released. In this case, the bit-qualified information is obtained on the bus 5 and written into the memory 1. In such a constitution, the bits can be qualified with the minimum necessary number of component elements.

Title: Direct-current restorating device
Inventor: ANZAI SHOZO
IPC: H04L25/06
Filed: 1985-06-20
Abstract: PURPOSE:To prevent a threshold voltage from rising above a necessary value, and to shorten a resetting time and to reduce error data by inputting a spurious digital signal to a low-pass filter when a digital input signal has a dropout. CONSTITUTION:If the input signal has a dropout, the output of a dropout detector 9 goes up to H and a selector 10 selects a phase-synchronizing signal from a phase synchronizing signal generator 11 and outputs it to the low-pass filter 5 while inverting its H or L phase state. The filter 5 detects a feedback signal and feeds it back to a comparator 8, so that a regenerated digital signal appears at an output terminal 4. Therefore, the threshold voltage is prevented from rising above a necessary value.
