Title: Impact-detecting mechanism for magnetic disk device
Inventor: IWABUCHI MASANORI
IPC: G11B19/04
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To detect impact which may cause off-track and destruction of data, at the time of R/W in a magnetic disk device. SOLUTION: The spindle motor system of the magnetic disk device 1 is provided with a rotational speed measuring device 6 which directly detects the speed variation of the rotational section of the spindle motor 3 in the tangential direction. The measurement of speed variation in the angular speed can be substituted for the rotational speed measuring device 6. Thus, the measuring device 6 detects the impact applied to the disk device 1 by the rotational speed variation of the spindle motor 3, and when the device 1 undergoes an impact, the measuring device 6 issues a R/W inhibiting command to the R/W controlling IC 8 on the PKG 7, to inhibit the R/W action of the magnetic disk device 1, thereby preventing the destruction of the data.

Title: Telephone set
Inventor: OGUSHI HIROSHI
IPC: H04M11/00
Filed: 1988-06-01
Abstract: PURPOSE:To receive the service which is not given if a tone signal is not sent even in a telephone set sending a pulse dial signal by devising the telephone set such that the pulse dial signal is sent before the line is connected and the tone signal is sent after the connection. CONSTITUTION:A dialer 7 is brought into the pulse mode through a control line 9 in case of the pulse line to be set. Then a control circuit 1 sends a number inputted from a ten-key 2 by the user from the dialer 7 to a telephone line 6 in a form of a pulse signal. When the polarity inversion takes place in the connected exchange with an opposite party replying the exchange, the control circuit 1 uses an incoming detection circuit 8 to detect the inversion and the control circuit 1 switches the pulse mode into the tone mode. Thus, the service unable to be used by the tone signal is utilized even via the exchange using a pulse signal.

Title: Low vacuum scanning electron microscope
Inventor: NAKAGAWA SEIICHI
IPC: H01J37/244
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To provide a low vacuum scanning electron microscope that is excellent in the efficiency of detecting reflected electrons. SOLUTION: A reflected electron detector 18 is placed in the peak position of an objective lens magnetic field, and an orifice 19 having a microopening is placed inside the detector 18. As a result, a differential exhaust ratio proportional to the cube of a diameter can be maximized, and a desired pressure difference can be produced between the inside of a liner tube 12 and the inside of a sample chamber. Also, reflected electrons produced from a sample 4 collide against residual gas and rise as they are diffused, but since the magnetic field intensity of the objective lens increases as they rise, the diffusion area is bound in the direction of the optical axis of an electron beam, and the efficiency of detecting the reflected electrons is maximized since the diffusion area (diameter) is at its minimum on the principal plane (peak position of the magnetic field) of the objective lens.

Title: Suction pressure control device for pump
Inventor: TAKADA SHUHO
IPC: F04B49/06
Filed: 1988-06-02
Abstract: PURPOSE:To deal with pseudo-phenomena of load shutdown and improve the reliability of a plant by turning a suction pressure control means for pumps OFF when the deviation of an average load indication value from a load indication value before the generation of load shutdown is larger than a preset value. CONSTITUTION:When a load indication value P is abruptly decreased, output of a flip flop 24 turns ON after the elapse of a specified time, and the suction pressure of a feed water booster pump and a feed water pump not shown in the illustration is insured. After the elapse of an another specified time, an ON-delay timer circuit 31 is turned ON, and output of a hold circuit 27 is held for a fixed time. Further, when the load indication value P reaches a specified value, output of a subtractor 29 becomes larger than a preset value in a monitor circuit 30. Because output of an AND-circuit 32 becomes larger by ON-signals from each circuit 30, 31, the flip flop 24 is reset to OFF. Insurance of the suction pressure in each pump is thus automatically stopped.

Abstract: PURPOSE:To accurately measure a stroke by a method wherein the horizontal direction projection distribution of a variable density image processor is divided by a threshold value changing in succession and center-of-gravity addresses becoming max. in dispersion between classes due to a center-of-gravity address are set to upper and lower end points. CONSTITUTION:With respect to the horizontal projection distribution (histogram) obtained by a camera 3 and a variable density image processor 4, a control means 2 sets an arbitrary threshold value address k1 temporarily to separate the same into classes C1, C2. Whereupon, respective center-of-gravity addresses become U1a, U2a. Then, by changing the address k1 successively, the classes C1, C2 become a shape equally divided into two ridges and the center-of-gravity addresses U1n, U2n at this time respectively correspond to the upper and lower end point addresses of a pin 1 and the stroke of the pin 1 is calculated therefrom. By this method, a stroke can be accurately measured even with respect to horizontal projection distribution when there is a crack or chipping at the leading end part of the pin.
