Title: Disk controller
Inventor: MAEHARA KAZUO
IPC: G11B21/08
Filed: 1991-04-09
Abstract: PURPOSE:To continuously perform the patrol seeking and verifying at the time of restarting a system, from the value of a track address before the system is stopped. CONSTITUTION:A track address for patrol seeking and verifying is written in the prescribed area on the recording medium of a hard disk drive 12 at the constant interval, at the time of inputting the power, the track address written in the prescribed area is read and set to a patrol cylinder address register 113 as an initial value. Thus, at the time of restarting the system, the patrol seeking and verifying function can be restarted from the value of the track address at the time of stopping the system, and even in the system where the system stoppage is comparatively frequently performed, the patrol seeking and verifying function can be performed over the whole surface of the recording media.

Title: Surface construction having air holding function and formation thereof
Inventor: NOBUNAGA HISASHI
IPC: B63B1/38
Filed: 1995-03-31
Abstract: PURPOSE: To apply an air holding function to base material surface for forming an air layer between the base material surface and liquid, and ensure the prevention of liquid adherence thereto by forming the base material surface out of fine irregular parts covered with a material of low surface tension, and storing the air in the irregular part, upon contact with liquid. CONSTITUTION: A coating layer 4 made of powder grains having low surface tension and a binder 2 is formed on the surface of a base material 1. Also, the grains 3 having low surface tension are formed to project from the layer 4, and a fine irregular part 7 of projections 6 and recesses 5 is formed out of an aggregate of the grains 3. As a result, a contact area between the surface of the grains 3 and the liquid 8 is lessened and the air is contained in the section 7 as well as in an extremely fine irregular part 3a on powder surface itself. In addition, a contact area between the part 7 and the liquid 8 is reduced, and much of the air is held in the section 7. According to this construction, the liquid 8 can be properly prevented from adhering to the surface of the base material 1.

Title: Control method for soldering by laser beam
Inventor: SAITO KUNIHIRO
IPC: B23K1/00
Filed: 1985-04-12
Abstract: PURPOSE:To enable a good soldering by measuring the gradient in the temp. rise of the part to be heated at the initial period of the heating stage by laser beam and by deciding the optimal soldering conditions from said temp. rise gradient. CONSTITUTION:The laser oscillator 3 generates a laser beam 12 and irradiates the soldering part. The temp. of the soldering part 20 is detected by the temp. sensor 7 and fed to the main control device 2 as the information including the temp. thereof.

Filed: 1981-05-20
Abstract: PURPOSE:To measure the temperature error of a thermocouple to be measured accurately by heating a standard thermocouple and the thermocouple to be measured in a heating atmosphere while their tip parts are inserted into a single cap made of a good thermal conductor. CONSTITUTION:The tip part of a standard thermocouple 1 is inserted into a hole 5 of a cap 4 and the tip part of a thermocouple 2 to be measured is also inserted into a hole 6 of the cap 4 before the both are charged in a heating furnace 3. Then, the electromotive forces that those couples 1 and 2 generate are made to operate on each other, and their difference is amplified and recorded to obtain a temperature difference. The cap 4 is made of metal, or a good thermal conductor, so those thermocouples 1 and 2 are heated approximately to the same temperature, eliminating a difference in heating temperature due to a position difference between the both. In addition, the temperature variation width of the cap surface due to variation in the quantity of radiation heat from the furnace wall by an electric heater 8 is less than that in the cap.

Title: Controlling method for speed of mandrel
Inventor: UEDA MASAMI
IPC: B21B37/46
Filed: 1979-06-19
Abstract: PURPOSE: To prevent the quick increase of mandrel's winding speed for the strip, by decreasing the set point of the mandrel's speed limiter correspondingly to the speed command at the point of time that the strip's tail end runs out of the finishing final mill.  
     CONSTITUTION: At the point of time, SD point that the strip's tail end runs out of the finishing final mill, the switch 9 is closed, and the integrator 10 starts the integration for the output of the holding circuit 4. The output waveform of this integrator 10 becomes like as the figure (b) whose value is subtracted from the output value of the circuit 4 to be impressed on the adder 11. After that, at the point of time, DO point, the switch 3 is opened and the switch 12 is closed, in order to decrease the output of the circuit 4. As a result, the output of the integrator 10 becomes the side crawling condition. This condition is maintained until the point of time, LR point, at which the taper limiter is restored; at this LR point, the integrator 10 starts the electric discharge with a time constant, and the output of the adder 11 stops the tail end at ST point where the output of the circuit 4 becomes zero. Hereupon, the figure (c) shows the output of the adder 11, and this output is amplified 7 and is taken as the mandrel's speed command MSC.

Title: Pressure sensor using crystal vibrator
Inventor: FURUSAWA KAORU
IPC: G01L9/00
Filed: 1978-06-27
Abstract: PURPOSE:To measure pressure, particularly gas pressure with high accuracy by the beat signals of the oscillation frequencies of the 1st and 2nd crystal vibrators by bonding these two crystal vibrators on a supporting member having mutually independent recesses with said recesses being held hermetically closed. CONSTITUTION:A crystal vibrator holder 3, formed of the same stock as that of crystal vibrators 1, 2, are constituted to a shape having mutually independent circular recesses in its upper and lower portions. The crystal vibrators 1, 2 are bonded in such a manner as to hermetically close these recesses, thereby forming spaces 4 and 5. When the measuring gas pressure P1 is admitted into the space 4 through vent pipe 6 and a reference gas pressure, e.g., atmospheric pressure P2 is admitted into the space 8 through vent pipe 9, then the crystal vibrator 1 produces a frequency change owing to the differential pressure between the space 4 and space 8. On the other hand, no frequency change is produced in the crystal vibrator 2 because the spaces 5 and 8 are communicated by a vent hole 7, thus from the differential signals of the oscillation frequencies of both vibrators 1 and 2, the measuring gas pressure P1 may be measured.
