IPC: H05K7/20
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To improve the cooling ability by letting air flow in a space provided between a drive part and a package part. SOLUTION: A spacer 106 has a function for forming a space between a drive part 102 and a package part 103 of a hard disk device and enlarging the areas of both the parts in contact with air.

Title: Image forming device
Inventor: MIURA KUNIHIKO
IPC: G03G21/00
Filed: 1984-05-07
Abstract: PURPOSE:To evade the continuation of large power consumption of a fixing means and to save electric power by adjusting the power consumption of the fixing means with a signal from an external device which specifies a reference value. CONSTITUTION:A fixing device fixes toner on a transferred form, a heater heats a fixing roller, and a temperature detector 34 detects the surface temperature of the roller. Then, the output of the detector 334 is connected to a resistance R03 and input sides of comparators 136 and 137, so input voltages to those comparators vary according to variation in resistance value with the temperature detected by the detector 334. Namely, the input electric power increases as the temperature rises. Further, a voltage divided by resistances R06 and R07 is applied to the other input terminal of the comparator 136, whose output varies according to whether the input voltage is higher than the reference voltage or not. Therefore, when the reference voltage of the comparator 136 is lowered through a resistance R08, the temperature control of the fixing device is lowered and the power consumption is decreased to save electric power. On the other hand, the reference voltage of the comparator 137 is set lower than that of the comparator 136, so a temperature drop due to a fault is detected.

Title: Surface layer thickness measuring device for multilayer material
Inventor: UDAGAWA KENJI
IPC: G01B17/02
Filed: 1993-04-19
Abstract: PURPOSE:To efficiently and accurately detect the surface layer thickness of a multilayer material having a similar structure in a surface layer and an inner layer by providing a pulse generator for generating pulses at the leading edges of output signals from a low-gain amplifier and a high-gain amplifier, and measuring a time interval between pulse signals outputted from both low-gain and high-gain amplifiers. CONSTITUTION:An ultrasonic wave signal received with a vertical probe 2 is amplified through a low-gain amplifier 4, and an output signal 21 from the amplifier 4 is introduced to a leading edge pulse generator 10. When bottom echo height exceeds a preset threshold, a leading edge signal 22 for the echo is outputted and introduced to a measuring instrument 6. On the other hand, an output signal from the amplifier 4 is introduced to a high-gain amplifier 5, and amplified to such an extent where fine interface echo exceeds a prescribed threshold. When the signal is amplified so much, not only the interface echo but also diffused echo appear and a cause for an error is thereby formed. Thus, as the surface layer thickness of a multilayer material is normally approximately 10% of thickness, the thickness is preliminarily inputted to cause a prohibition gate generator 9 to operate. At the same time, the gain of the amplifier 5 is thereby restrained and the occurrence of an error is prevented.

Abstract: PURPOSE:To simplify wiring and avoid an accident due to wrong wiring and poor insulation by providing a branch device and switching a monitor circuit according to lock and unlock operation, so that the same circuit is switched to an operating current and a monitor current. CONSTITUTION:When an electric lock is locked, the first contact 6 of a lock- unlock switch 5 in a branch device 4 is closed, so that an electric current steadily flows through the first branch path 8 and a light emitting element 24 to light the light emitting element 24. When the electric lock is unlocked, the second contact 9 of the lock-unlock switch 5 is closed, so that a monitor current flows through the second branch path having the second diode 11. The second diode 11 is intermittently short-circuited by the operation of a current flicker circuit, so that a light emitting element provided in an interior side controller 12 is lighted up and out. Thus, the same circuit can be switched to be used for an operating current and a monitor current.

Title: Device simulator
IPC: G06F19/00
Filed: 1992-03-17
Abstract: PURPOSE:To obtain a solution stably and fast by performing device simulation wherein an external element is mounted by virtually adjusting the value of the external element until the solution sufficiently approximates the truth. CONSTITUTION:In the process of device simulation calculation, it is decided whether or not the calculation result is close to the true value and when the value approximates the true value, the value of the external element is virtually adjusted so as to quicken the convergence of the value, but put back to the original value when the value approximates the true value. Then the boundary condition of the electrode to which the external element is connected is calculated and then use to generate an equation to be solved. This equation is numerically solved and it is decided whether the solution is converged; when the solution is converged, the process is ended, but when not, the process is repeated. Namely, the value of the external resistance (current value I0, external resistance R, external capacity, or external inductance) is virtually adjusted in the beginning of the numerical calculation to accelerate the approximation to the real solution and then put back to the original value when the solution approximates the true solution to some extent.
