Title: Method and apparatus testing pressure resistance of heat exchanger
Inventor: SATOU JIYUNICHI
IPC: G01N3/10
Filed: 1979-09-05
Abstract: PURPOSE: To perform pressure resistance test in a short time by making use of the impulse impact pressure of fluid packed in a core.  
     CONSTITUTION: A cup-shaped sealing body 10b is fixed to one side of a core support base 11 snd a cup-shaped sealing body 10a is movably disposed to the other. The supply pipe 14a and discharge pipe 14b of a fluid circuit 15 of heated fluid or ordinary temperature fluid are connected and the fluid circuit 15 is connected to an impulse generating section 19. After a core 2 is grasped by the cup-shaped sealing bodies 10a, 10b therebetween, the heated fluid or ordinary temperature fluid is filled in the core 2, particularly in the liquid pipe 7, after which impulse of 0W 1.6kg/cm 2  is applied multiple times to the fluid filled to apply multiple impact pressure instantaneously to the core 2. As a result, the core 2 repeats expansion and contraction and its material fatigues early, thus the pressure resistance test is carried out in a short time.

Title: Magnetic disk device
Inventor: NAKANO YASUMASA
IPC: G11B5/55
Filed: 1992-05-06
Abstract: PURPOSE:To correct the offset value and the gain automatically and only as necessary with no use of a special sensor in order to cancel the offset occurring in a head positioning control system. CONSTITUTION:In a seek control state of a head 1, a CPU 10 produces an offset correction signal based on the offset value stored in a memory 12 and inputs this signal to an amplifier 6 via a D/A converter 9. An amplifier 6 inputs the signal obtained by adding the offset correcting signal to the error signal outputted from a servo signal producing circuit 6. Based on these added signals, the current supplied to a VCM 7 is changed and the head 1 is set at the center position of a target cylinder with no offset caused. At the same time, the CPU 10 measures the settling time of the head 1 by a timer 11. When the difference between the measured settling time and the standard time exceeds a prescribed range, the CPU 10 corrects again the offset value stored in the memory 12 and also sets again the gain of an amplifier 51.

Title: Freezing show case
Inventor: SAEKI TATSUO
IPC: F25D23/02
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To protect the glass at the ceiling by using a transparent flexible resin sheet. SOLUTION: In a display case double glass 7 constituting a front panel is set from the front to the topside. A transparent flexible resin sheet 50 is laid on the ceiling face 7A of the double glass 7. Hereby, the sheet 50 protects the glass 7, and besides the glass 50 absorbs shock, being made of material of soft resin, so it can prevent the glass 7 from being damaged or broken. Moreover, since the resin is lower in heat conductivity and is more excellent in heat insulating property than glass, the dew condensation is hard to occur at the surface, and the cold heat within the exhibition room is hard to get away.

Filed: 1982-06-29
Abstract: PURPOSE:To simplify a DC/DC converter circuit by adding a coil to an oscillation transformer, opening or shortcircuiting the circuit of the coil to turn ON or OFF the oscillation of the converter, thereby effectively operating it without error. CONSTITUTION:When a switch SW is opened, the impedance of a transistor Q5 exhibits the value near infinity, an oscillation is started by the starting operation of a closed circuit of a coil N1, a capacitor C3 and a transistor Q4, and the oscillation is maintained by the feedback of a voltage by the coil N1 and the feedback of a current by the coil N4. Since the impedance of the transistor Q5 becomes very small value when a switch SW is closed, the coil N4 of an oscillation transformer T2 is shortcircuited via an extremely small impedance. In this manner, the drive of the oscillation transistors Q1, Q2 of the converter is stopped, and the voltage between the output terminals 3 and 4 of the converter becomes zero.
