Title: Mass analyser and electrode heating method
Inventor: TAKADA YASUAKI
IPC: H01J49/34
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To improve analysis precision of an ion trap mass analyzer by providing an inductance coil in the vicinity of a ring electrode and high-frequency heating the ring electrode by Joule's heat after generating eddy current on the ring electrode. SOLUTION: When a magnetic field is induced by an inductance coil 11, a ring electrode 5 generates an eddy current having an action for eliminating variation of that magnetic field. When an eddy current flows this electrode 5, Joule's heat is generated because of electric resistance of an electrode, and the ring electrode 5 is heated. The ring electrode can be heated efficiently by feeding an a.c. current to this coil 11 using an AC power source 12. In analysis of samples, after the samples are separated by a GC1, it is fed to an ion trap mass analyzer 3 by a pipe 2 together with carrier gas. The samples are ionized by an electron beam 9 to be discharged from an electron gun 8, stored in the mass analyzer for a constant time, and then mass-analyzed. The mass- analyzed ion is detected 10, and its output is processed by a data processor.

Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To smoothly stop an alarm tone and other notification tones by stopping the notification tone generated in response to the signal sent from an originating device via the operation of a call button. SOLUTION: When an originating signal is received from a button device 20 serving as an originating device or a sensor 21, a notification tone is outputted from a speaker 7 and also a notification pilot lamp 4 or 4a blinks. When a call button 5 is pushed under such conditions, the notification tone outputted from the speaker 7 is stopped while the lamp 4 or 4a is blinking. Thus, the button which is usually used as a hand-free interphone function is also used as a button that stops the notification processing. As a result, the notification tone can be smoothly stopped even while the notification tone is ringing just by operating the familiar button 5. Furthermore, a plate push-button of a large size that can be operated by an elbow when busy is also available.

Title: Motor driving device for camera
Inventor: KAWAMURA MASAHARU
IPC: G03B17/00
Filed: 1985-09-27
Abstract: PURPOSE:To improve the stop position precision of an object to be driven by providing a control means which performs speed reduction control over a motor before the stop position of the object and stop control at the stop position when a speed variation ratio is high and performs the stop control before the stop position of the object without performing the speed reduction control over the motor when the speed variation rate is low. CONSTITUTION:When a detecting means 8 detects winding operation being almost completed, the control means 2 decides between the high and low deceleration ratios. In fast single-shot mode, the control means 2 varies the driving signal to a driving circuit 3 with duty and lowers the level of the driving voltage to performs the speed reduction control over the winding motor M2. When the detecting means 8 detects the completion of the winding operation, the control means 2 outputs the stop signal of the motor M2 and performs the stop control. Thus, the winding motor M2 is reduced in speed from before the winding completion point when the speed variation ratio is high, so the moving speed of a film is considerably low at the winding completion detection point and the film 7 is stopped with a short overrun beyond the winding completion detection position.

Abstract: PURPOSE:To obtain sufficient accuracy and performance by using metal of single crystal structure. CONSTITUTION:The polygon mirror 1 whose sectional shape perpendicular to its rotary shaft is regularly polygonal is made of the metal of the single- crystal structure. Therefore, there is no crystal grain boundary present, so there is no fine step formed on a reflecting surface and neither the flatness nor reflection factor decreases. Further, the crystal azimuth is coincident at any part in the same reflecting surfaces 1a-1b, so a cutting direction to the crystal azimuth is made coincident over the entire area and variance in reflection factor in the same reflecting surfaces and among the reflecting surfaces is reduced. Consequently, the polygon mirror which has enough accuracy and performance for application to a high-performance laser printer, etc., is easily obtained.
