Title: Production of magnetic disk
Inventor: MORITA TOMOJI
IPC: G11B5/64
Filed: 1985-01-11
Abstract: PURPOSE:To improve the reliability owing to an increase in the number of contact start stop CSS by using the decomposed polymn. product of ammonium silicate to form an SiO2 film on a magnetic metallic oxide recording medium. CONSTITUTION:After a sputtered gamma-Fe2O3 film is formed on a disk-shaped alumi num alloy substrate, about 10% ammonium silicate soln. is coated thereon by a spin coating method. Such circular disk is heat-treated at 300 deg.C in an electric furnace. The formation of the SiO2 film by the low-temp. heat treatment is made possible n the above-mentioned manner, by which the number of CSS is increased and the trouble by a head crash is decreased. The cost reduction is made possible by using an inexpensive raw material and the reliability is improved.

Title: Solenoid driving apparatus
Inventor: FUJIWARA MASARU
IPC: H01F7/18
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a driving apparatus, which can secure a stabilized driving force with a simple constitution. SOLUTION: A solenoid 14 is driven by a solenoid driver 13 by using a driving current immediately before the previous off held in a backup memory 15 at the time of initialization. The time required for driving is obtained from the change in single state of a position detecting sensor. The driving time and present specified time are compared. When a load becomes heavy and the time is too slow at this time, the driving current is sequentially made large by changing on-duty ratio. When the load is light and the time is too quick conversely, the driving current is sequentially made smaller by changing the on-duty ratio. Thus, the optimum driving current is obtained.

Title: Measuring apparatus for power data
Inventor: OZAWA SATOSHI
IPC: H04Q9/00
Filed: 1991-01-18
Abstract: PURPOSE:To avoid an overload state by holding a measuring data obtaining request and successively obtaining measuring data corresponding to the data holding capacity of a data transmission device. CONSTITUTION:A measuring data obtaining command is applied to arbitrary power apparatuses 5,6 from a measuring data obtaining command part 1 to be stored in a memory part 2. The measuring data obtaining request to a data transmission device 4 is performed by taking out a command from the memory part by a measuring data obtaining request part 3. The data transmission apparatus 4 takes out the measuring data of the power apparatuses 5,6 receiving the measuring data obtaining request to return said data to the request part 3 to display the same on a display part. The request part 3 compares the generation quantity of the measuring data obtaining command with the measuring data return quantity receiving the command and, when the overload of the device 4 is detected, the request part 3 waites for the measuring data obtaining request to the device 4. When the measuring data obtaining command of the B power apparatus 6 is received before the measuring data of the A power apparatus 5 is returned, the request part 3 holds the request and issues the request to the B power apparatus 6 at the point of time when the data from the A power apparatus 5 is returned.

IPC: F16K31/06
Filed: 1982-01-13
Abstract: PURPOSE:To contrive to stabilize the operation of the valve by a structure wherein the entry of bubbles into the sliding gap of a plunger from a valve chamber is prevented. CONSTITUTION:The rising part of the cylinder of a cup-like part 12 mounted to a valve body 5 is rendered to indent the annular convex groove 4 provided on the ceiling of a valve chamber 1 so that the passage led from a valve seat block 3 to a sliding gap A is directed downward from once and in addition at least a part of the opening of an outflowing port 15 is located above the upper edge of the cup-like part 12.

Title: Initial condition set circuit
Inventor: IMAI KIYOSHI
IPC: H04N5/00
Filed: 1982-01-13
Abstract: PURPOSE:To prevent the malfunction at switching of main power supply and at fluctuation, by comparing a comparison voltage with the 2nd reference voltage and releasing the operation inhibiting state of a control objective circuit after the release of the operation inhibition of a microcomputer. CONSTITUTION:A reference voltage VB generated at a reference voltage generating circuit 15 is made higher than a reference voltage VA to compare a conversion voltage Vc at a comparison circuit 19. That is, in the Vc converting a power supply voltage VM at an input terminal 11 at a conversion circuit 17, a reference voltage VB is increased than the voltage VA being the output change of a comparison circuit 16, and an input power supply voltage is reaches a V2 being higher than V1, then an output of a comparison circuit 19 has a change. The comparison output of the circuit 19 is converted into a voltage which inhibits the operation of a channel selection section 10 while the input power supply voltage VM does not reach the V2 and starts the operation in releasing the inhibition after reaching the V2, and this is taken as an output B and applied from an output terminal 13 to the section 10.

Title: Heat accumulator
Inventor: RIYOUDORI MICHIO
IPC: F28F23/02
Filed: 1980-01-21
Abstract: PURPOSE: To facilitate separation of the heat accumulating material crystal having attached to  the periphery of the heat exchanging fins of a heat accumulator by placing on the latent heat  accumulating material in the heat accumulating container a liquid which is insoluble in said  material and disposing heat exchangers for cooling on the boundary surface therebetween so that  a portion of each heat exchanger is dipped in said latent heat accumulating material.   
     CONSTITUTION: When a low-temperature heat medium is made to flow in each heat exchanger 6  for cooling in order to collect the heat in a heat accumulating material 3, the heat accumulating  material 3 around each fin 6b crsytallizes to attach thereto. In this case the liquid 5 around each  pipe 6a is also cooled, so that the boundary surface 7 between the liquid 5 and the heat accumulating material 7 also becomes a heat transmitting surface, also from which the heat accumulating  material 3 is cooled. Accordingly, the heat accumulating material crystals 4 each having attached  to the periphery of the fin 6b are unitarily connected together between adjacent fins 6b. When the  thickness of the crystal 4 increases and consequently its thermal resistance increases, a high- temperature heat medium is made to flow in the pipes 6a in order to liquefy the crystal 4 and  separate it from the fins 6b. Thus, the separation of the heat accumulating material crystal is  facilitated, and the fall in the heat transmission amount is prevented as well as the utilization  rate of the heat accumulating material is improved.
