Title: Positioning circuit for magnetic head
Inventor: TAKI YOICHIRO
IPC: G05D3/00
Filed: 1985-03-15
Abstract: PURPOSE:To reduce the cost by providing a sample-and-hold circuitinputting an output of a DA converter to eliminate the need for a DA converter for generating an AGC reference signal. CONSTITUTION:When a magnetic head is in track follow operation, a binary value corresponding to an AGC reference signal 6 is added as a DA converter input signal 1. In this case, a sample-and-hold control signal 5 is at a low level and an analog switch 13 is set, then the AGC reference signal 6 is generated in the output of an operational amplifier 14. When a magnetic head is in seek operation, the signal 5 goes to a high level and the switch 13 is reset, then a voltage before the switch 13 is turned off is kept by a hold capacitor 12 and the same AGC reference voltage is kept even during the seek operation. In this case, as the signal 1, a binary value is added corresponding to the signal 3 and the DA converter 2 outputs the signal 3. Thus, a DA converter for generat ing the AGC reference signal is not required.

Title: Aromatc unit
Inventor: SAKAMOTO SUSUMU
IPC: H02P7/288
Filed: 1985-03-19
Abstract: PURPOSE:To uniformly maintain odor effect by reducing the rotation of a blower immediately after an odor and battery are periodically replaced, and increasing the rotating speed as time is elapsed to cause a voltage to drop. CONSTITUTION:A current is not flowed to a transistor 3 in the state that the battery voltage Vb of initial elapsing time is high, and a current is not flowed to a drive transistor Q5 of a motor 4. Accordingly, a motor voltage VMO becomes OV. Then, when a time is elapsed so that a battery voltage Vb drops, a varying voltage VC decreases, and a difference from a fixed voltage VS reduces. Thus, the current of a transistor Q4 increases, the current of a motor drive transistor Q5 is increased to increase the speed of the motor 4. The rise of the motor speed is continued until the battery voltage Vb becomes substantially equal to the motor voltage VMO.

A block identification number and a check bit for error detection are added to this block by the control information adding circuit 2. Signals led from the adding circuit 2 are temporarily stored in a buffer 3, and a signal having the requested block identification number is outputted to a signal synthesizer 4 when a retransmission request signal is received by a confirmation signal discriminating circuit 7. These signals are erased in the buffer 3 when a certain time elapses after input of signals from the adding circuit 2, and only signals retransmitted within the certain time are handled as information signals. In a receiver 20, it is discriminated by an error detecting circuit 10 whether signals received by a terminal 9 include error or not, and a confirmation signal generator 13 transmits the retransmission request signal to the transmitter 20 through a terminal 14 in accordance with the discrimination result.

Title: Manufacture of fiber reinforced phenolic resin molded form
Inventor: MAKIYO TAKESHI
IPC: B29K61/04
Filed: 1986-03-13
Abstract: PURPOSE:To obtain prominent workability, mechanical strength and heat resistant property by a method wherein the condensate of naphthalenesulfonic acid formalin, provided with the predetermined rate of sulfonation coefficient, is employed as acidic curing agent. CONSTITUTION:The condensate of naphthalenesulfonic acid formalin, employed as an acidic curing agent for the precondensate of resol type liquid phenolic resin, is shown by a formula (1) and the rate of sulfonation is preferable to be 60-100%. When the rate of sulfonation is up to 60wt%, solubility in water and resin is not good and the cure rate thereof is slowed unless otherwise a big amount of the same is used. When the rate of sulfonation exceeds 100%, heat generation and the increase of viscosity are quick while the corrosion property of fiber reinforced molded form against a metal is high. When the curing agent of predetermined rate of sulfonation is employed, emulsification after blending is slow and initial increase of viscosity is small, therefore, workability is good and the resin may be cured quickly. At the same time, molded fiber reinforced form is provided with good resistance to heat.
