Filed: 1992-09-29
Abstract: PURPOSE:To increase the speed of a tape at the time of searching by changing the rotating speed of a reel driven only by switching operation to a rotating speed preset in advance. CONSTITUTION:When the search in the FF direction begins by a command from a CPU, the circuit constant of a servo amplifier 17 is set and the output of a driver 16 is controlled. A take-up reel 11 is rotated by a reel motor 12 and a generated FG is detected by a detector 13. The rectangular wave output is converted to a voltage output by means of an F/V converter 14 and fedback to an amplifier 17. At this time, a supplying reel 22 rotates while keeping the tape tension constant and generates an FG. The FG is detected by an FG detector 23 and a voltage according to the FG frequency is outputted through an F/V converter 24. The output is fed back to the amplifier 17. On the other hand, the outputs of converters 14, 24 are compared by a comparator 15, a changeover circuit 18 for rotating speed is switched according to the L or H of the difference of the outputs, the constant of the amplifier 17 is changed and the motor 12 is rotated at a first or a second rotating speed.

Title: Transfer part control system
Inventor: IGAWA HARUO
IPC: B41J2/44
Filed: 1986-11-26
Abstract: PURPOSE:To suppress the occurrence of noise by inverting output states of a control signal and a target value signal when a transfer member is placed in a prescribed position before the open position. CONSTITUTION:A position sensor 9 detects the position of a DC motor 7 to send a position signal 101 to a position control circuit 8 and a control part 2. The position control circuit 8 amplifies the inputted position signal 101 to send a position control signal 102 to a switch circuit 5. An adder 4 sends an addition signal, which is obtained by synthesizing a target value signal 105 inputted from a target value generating circuit 3 in the control part 2 and the signal obtained by inverting the polarity of a switch signal 104 inputted from the switch circuit 5, to a power amplifier 6, and the power amplifier 6 amplifies this signal 106 to obtain a driving signal 107 and sends this signal 107 to drive the DC motor 7. Thus, noise does not occur because a transfer plate is not allowed to mechanically strike against a stopper for the purpose of stopping the transfer plate.

Filed: 1993-11-12
Abstract: PURPOSE:To reduce the unnaturality of a decoded image by stopping the read of a code stored in a buffer memory and reading the code repetitively from an image memory based on the result of comparison of the code quantity stored in the buffer memory with 1st and 2nd thresholds. CONSTITUTION:A code buffer memory control section 101 always monitors the relation between a coded data quantity notice signal if and each of thresholds L1-L4 based on each output of comparators 1041-1044 while conducting usual decoding. When the coding data quantity notice signal 1f is less than the threshold L1, the supply of coded data is stopped by a control signal 1a of a coded buffer memory 102 and an image stored in an image memory 105 is outputted instead. When the signal 1f is less than the threshold L2 and the decoded frame is an I-picture or a P-picture, a similar operation is conducted. When not, the succeeding frame is decoded and the coded data quantity is compared again. When the signal 1f is more than the threshold L3, overflow processing is conducted.

IPC: G11B5/09
Filed: 1986-11-28
Abstract: PURPOSE:To erase a data block detected for an error by erasing a block having a write error after a preceding block to the block having the write error. CONSTITUTION:A write/read control circuit 20 activates an error detection circuit 6 and a block number detection circuit 7 through a read gate control circuit 5 to read the (N-1)th data block (N-1). The error detection circuit 6 reports the absence of the error in the (N-1)th data block (N-1) to the write/read control circuit 20. The write/read control circuit 20 receives the report to activate a write amplifier 23 through the write control circuit 22 and uses a write head 24 to erase the N-th data block N having an error. Thus, the block having write error is surely erased.

Filed: 1990-10-22
Abstract: PURPOSE:To send a signal even when an active frame between the active frame employing a standby system and the standby system is removed by connecting newly a transmission medium between the active frame and the standby frame and changing a selection destination of a high speed side standby system switch. CONSTITUTION:In order to distribute a standby system high speed side input signal P to active frames 2,3, transmission media 16,19,20 are connected and selectors 7,9,11 select their contact destination. In this method, when the standby system high speed side input signal P is used as an active system high speed side input signal W2, the standby system high speed side input signal P passing through the active frame 2 is sent from a low speed side signal processing section 6 as a low speed output signal S2. Moreover, a transmission medium 21 is connected between terminals 22 and 23. When the selector 11 in the active frame 3 selects the transmission medium 21, the signal P is directly inputted to the active frame 3 through the transmission medium 21 not through the active frame 2.

Title: Assembly of bound ring-like products and method of binding
Inventor: SAITO MASAYUKI
IPC: B65B27/06
Filed: 1987-11-10
Abstract: PURPOSE:To effect an easy and efficient packing operation, by fitting a number of ring-like products alternately into the two core portions of a core metal which is formed into a U-shape consisting of a parallel pair of the core portions joined at the bottom and by providing spacer rings or use with the aforesaid portions. CONSTITUTION:When packing washers 6, they are fitted alternately into the core portions 2 and 3 of a metal core 1 with a space ring 5 set between each washer. After setting the uppermost washer 6 and spacer ring 5, the upper parts of the core portions 2 and 3 are bent outward at a right angle over the uppermost spacer ring 5 and these two bent portions 2a and 3a prevent the disengagement of the washers 6 and the spacer rings 5. Thus, a number of the washers 6 are arranged in two rows along these core portions 2 and 3 and overlapping one another in multiple tiers, whereby the washers are fixedly packed between the bottom portion 3 of the metal core 1 and the bent portions 2a and 3a. This method permits an easy and efficient packing of the washers in a compact form, leading to the increased treatment ability per operation such as in tempering.
