Title: Tape positon detector
Inventor: KOMORI KATSUFUMI
IPC: G11B27/17
Filed: 1981-05-08
Abstract: PURPOSE:To increase the detecting accuracy of the tape position and to feed automatically the tape up to the set position, by using an object to be detected which turns synchronously with a tape feeding reel shaft and eliminating an error between the actual tape position and a counter output value. CONSTITUTION:A rotary disk 2 plus detectors 3a and 3b, i.e., the objects to be detected for detection of the tape position are attached to a tape feeding reel shaft 1. The disk 2 contains a part 2a of a high optical reflection factor and a part 2b of a low optical reflection factor. the detectors 3a and 3b comprise light emitting elements 3a1 and 3b1 plus photoelectric transducers 3a2 and 3b2 respectively. Furthermore the detectors 3a and 3b are distributed so as to range tape position detection signals 21 and 22 in the phase difference 0 deg.<tape position detection signal <180 deg. respectively. An FF5 and an FF7 are actuated by the signals 21 and 22 respectively, and the tape travelling direction is discriminated. Then the relative value of the tape position is counted by a counter 11. This counted value is compared 13 with the relative value at the desired position of the set 12 tape. Thus the feed of the tape is controlled 14.

Title: Magnetic disk device, and method of head control
Inventor: TAKIZAWA TOSHIMITSU
IPC: G11B21/08
Filed: 1995-03-28
Abstract: PURPOSE: To inhibit the fluctuation of a yaw angle at the time of seek operation, and to suppress the lowering of the dynamic floating quantity of a head and prevent the generation of trouble by controlling seek maximum speed or target speed in response to the seek direction of the head. CONSTITUTION: A control circuit 8 for the place of a head obtains the speed of travel of the head 1 from the current place of the head and the place of the head before the current place of the head by one acquired from a servo-data detector 7. The direction of movement of the head 1 is discriminated, and target speed to a target cylinder is determined by using a seak acceleration table corresponding to the direction of movement previously stored in a ROM. That is, seek target acceleration at the time of the seek of an outer circumference from an inner circumference is decreased, and that at the time of the seek of the inner circumference from the outer circumference is increased.  Accordingly, speed or acceleration is controlled in response to the seek direction when the head is sought, thus inhibiting the increase of a yaw angle and suppressing the lowering of the quantity of the head floated, then preventing the generation of trouble such as head crush and improving reliability while allowing high- density recording.

Title: Method and device for duplicating auxiliary storage medium
Inventor: HASHIZUME TATSUO
IPC: G06F3/06
Filed: 1989-03-22
Abstract: PURPOSE:To utilize information being not updated by starting duplication from the maximum address, immediately interrupting the duplication at the time of receiving an interruption command deciding result from an interruption deciding stage, subtracting duplicated addresses in address subtracting stage, and setting up the subtracted value as a new duplicated address. CONSTITUTION:At the time of receiving a duplication starting command from an operator, a start deciding part 1 reads out the maximum address and applies the read address to an address specification part 4. An interruption deciding part 2 interrupts and ends all the processing in the case of an operator's duplication interrupting command. When the command is not the interruption command, a reading part 5 reads up an address stored in an auxiliary medium which is specified by the reading address specifying part 4. A writing address specifying part 7 specifies the same address as the one specified by the specification part 4 as a writing address. A writing means 8 writes the information read out by the reading part 5 in the address specified by the specification part 7. An address subtracting part 6 subtracts the address read out by the reading means 5 from the address specified by the specification part 4 to find out the address for the succeeding reading and the address is supplied to the specification part 4.

CONSTITUTION:A coagulating agent is extruded from an extruding hole 9 which is a small gap formed on the lower end circumferential edge of an outer side wall 6 of a pressure controlling chamber 11 for forming a flowing-down liquid film, and forms a liquid film 16 flowing down in a hanged bell shape in a body 1 of an instrument. On the other hand, a stock solution supplied in a cup 12 of an atomizer is flown by means of a centrifugal force due to the rotation of the cup 12 and thereby made into liquid drops 17, which contact with the inner face of the liquid film 16 of the coagulating agent flowing down in the hanged bell shape and become coagulated solid granules 18. The coagulated solid granules 18 and the coagulating agent flowed down in a film shape are gathered in a bottom center along a hopper-shaped inclined bottom plate 3 of the instrument 1 and discharge out of the system from a discharging tube 15 connected with the inclined bottom plate 3. Discharged granules and coagulating liquid are separated by means of a known device and the granules are sent to such treatments as classification, heat treatment, drying and so on in accordance with the purpose.

Filed: 1995-03-06
Abstract: PURPOSE: To clarify a failure spot and to allow quick determining so as to improve maintenance and a quality for a user by recognizing that a safety circuit operates independently from a system control section via a notifying means provided in the safety circuit. CONSTITUTION: A system control section 12 drives a heating control fixing roller, detects a temperature, etc., and outputs a pattern signal SG4 and a power conductive pattern generation section 14 drives and stops a heater 6 based on this signal SG4 and controls heating. When a voltage VT from a thermistor 3 provided on the surface of the fixing roller drops below a fixed value (when a surface temperature becomes an abnormal value Tb higher then an abnormal value Ta for control), a safety circuit 15 excites the relay 16 of a stransistor 18 and stops supplying of AC power to the heater 6. Then, the circuit 15 outputs a signal SG5 to the system control section 12 and notifies driving of the relay 16. Thus, when there is no increase ocurring in the temperature even after power is conducted to the heater 6, its cause is made clear.

IPC: B41J2/05
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To eliminate deterioration of quality due to satellite by inclining the ink ejection plane against an ink channel. SOLUTION: Hitting positions of main drop and sub-drop are matched by inclining the ejection plane. Inclining direction of the ejection plane is determined by the relation of the magnitude of surface energy on the heater board surface 10 and the nozzle resin surface 11 and the ejection plane must be inclined such that the nozzle length is shorter for the smaller surface energy. An optimal inclination angle is determined by performing conditioning through try and error. Cutting on a plane determining the length of liquid channel from a common liquid chamber 8 to a delivery opening 6 is performed to incline the ejection opening plane by inclining a stage. In order to attain that inclination, cutting is performed from the heater board side and the inclination angle is set at about 50 deg. where satellite is eliminated.
