When the print PR is inverted at the termination of printing, the counter 2 indicates up-counting, and adds the set value and the up-counting value of the generated pulses of the generator 11 connesponding to the distance l 2  of the paper 8 to travel from the transfer position to fixing position. Then, according to the reverse direction paper feed instruction PRV, the counter 12 counts down until the addition content becomes zero, so that the paper is moved reversely by the distance of l 1 +l 2 . Therefore, at the time of next printing, the printing may be made next to the last line in the previous printing without leaving blank.

Title: Simultaneous command information transmitting system
Inventor: NISHIHARA KENICHI
IPC: H04B7/24
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To improve the transmission performance of information at the time of issuing a simultaneous command by automatically and individually transmitting the simultaneous command to stations which do not send an acknowledgement. SOLUTION: At the time of issuing a simultaneous command, a simultaneous command starting signal is transmitted from a master station 1, while a terminal station 2 gives a simultaneous command to a terminal unit 3, and sends a connection confirmation signal to the master station 1 followed by an acknowledgement. The master station 1 sends a simultaneous command start signal to the terminal station 2 and sends simultaneous command information. The master station 1 sends an acknowledgement instruction signal to the terminal station 2. The terminal station 2 requests the terminal unit 3 to make an acknowledgement. The master station 1, after identifying non-reception of the command, generates the individual communication call number of the terminal station 2 and calls the terminal station 2 by individual communication.  The terminal station 2 starts call incoming call by the terminal unit 3. The terminal station 2, after receiving a response from the terminal unit 3 sends a terminal unit response to the master station 1. The master station 1 sends simultaneous command information to the terminal station 2. The terminal unit 2 which normally receives simultaneous command information sends a termination signal to the master station 1.

Title: High-response injection speed sensor
Inventor: OSONE MASANORI
IPC: G01P3/42
Filed: 1986-03-04
Abstract: PURPOSE:To increase a response speed and to remove a ripple effectively by letting a subtracter calculate the difference between the counted value of pulses generated at every time the screw of an injection molding machine moves by fine distance and the output of an integration circuit. CONSTITUTION:Pulses generated by a pulse encoder 1 at every time the screw of the injection molding machine moves by the fine distance are counted by a counter 2. The difference between the counted value and the output of th integration circuit 4 is calculated by the subtracter 3 and inputted to a low-pass filter 6 through a high gain amplifier 4. The low-pass filter 6 varies in cutoff frequency with the output and a speed output is obtained. The response is determined by only the gain of the high gain amplifier 4 and the cutoff frequency of the low-pass filter 6 varies with an input, but the frequency band of the ripple while held in an attenuation range varies so that a passing band is obtained up to as high frequency as possible.

Abstract: PURPOSE:To prepare a dressing resistant to browning over a long period and stably keeping the taste and flavor, by compounding sorbitol to a dressing containing a proteinous fermented seasoning. CONSTITUTION:An emulsion-type or separation-type dressing containing about 1-40% of a proteinous fermented seasoning as a part of the raw materials, e.g. MISO (fermented bean paste) or soy sauce, is compounded with about 1-30% of a sorbitol such as D-sorbitol or L-sorbitol and the objective dressing is prepared from the obtained mixture according to the conventional method for the preparation of a dressing containing a proteinous fermented seasoning. Since sorbitol is soluble in water, it is preferably added to the aqueous phase. The browning phenomenon of the dressing occurring in the long-term storage and caused by a proteinous fermented seasoning can be effectively prevented by this process.
