IPC: G03B17/00
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To record magnetic data with proper bit density in a preset magnetic recording area. SOLUTION: When the leading end of perforation is detected by a perforation sensor (#210), the pulse number of detection signals of a motor rotation sensor starts to be counted (#220), and subsequently, the film feed speed is calculated from the count pulse parts when the trailing end of the perforation is detected by the perforation sensor (#230). That is, the film feed speed is calculated (#250) from the size of the perforation and the pulse number of detection signals of the motor rotation sensor output in the meantime. Subsequently, the recording frequency of magnetic data is calculated using the calculated film feed speed (#260).

Title: Method of positioning and adjusting size and position of rectangular beam for charged particle beam lithography
Inventor: TAKEMURA HITOSHI
IPC: H01L21/027
Filed: 1994-02-10
Abstract: PURPOSE:To provide a method of facilitating accurate adjustment of the size and positioning deflector of a rectangular beam. CONSTITUTION:An opening 37 of a knife edge 32 is irradiated with a rectangular beam. An electron beam is made scan twice in the direction of an arrow X, and detection signals of a Faraday cup 33 obtained through each scanning are differentiated by a differentiating circuit 34, which are stored in a memory 36 through a computer 21. As the scanning starting points of a first and a second scanning carried out by an electron beam are made to deviate from each other by a size of a rectangular beam, a joint between two signals becomes flat when an actual rectangular beam is formed as large in size as prescribed. But, when a rectangular beam is not set in size as prescribed, a joint between two signals grows recessed or protrudent. A device is controlled so as to make a rectangular beam as large in size as prescribed based on a joint of two overlapped signals.

Title: Webbing for seat belt

IPC: B60R22/12
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To reduce a frictional resistance against a webbing guide through usage for a long period of time by installing a range of low-friction strings sewn along the longitudinal direction on the surface of a webbing so as to be dispersively projected. SOLUTION: Low-friction stings 31, which are sewn into a webbing 21 and dispersively projected onto the surface of a webbing body 22, directly come into contact with a sliding surface 24a of a through anchor 24, and thereby its frictional resistance with this through another 24 is reduced. At this time, since the extent of frequency that the webbing body 22 is directly contacted with the sliding surface 24a of the through another 24 is considerably abated, the low-rubbing strings 31 are able to bring its frictional resistance decrement effect into full play.  In brief, the webbing 21 is manufactured by a simple manufacturing process that plural lines of low-friction stings 31 are merely sewn along the longitudinal direction so as to be dispersively projected onto the surface of the webbing body, whereby the frictional resistance again the through anchor 24 is reduced through a long period use.

Abstract: PURPOSE:To improve the accuracy of the adjustment of registration, by detecting the difference between an output signal of a reference image pickup tube with that of other pickup tubes, and compensating and controlling the beam deflection while adjusting compensation data by a prescribed amount. CONSTITUTION:An output of the reference (green) G tube passes through a 1H delay line 5 and a T delay line 7 and is led as a main line signal G0. The output of the delay line 7 is delayed at a T delay line 8, the output is subtracted by the input of the delay line 7 and an edge signal EDG is obtained. The signal EDG is applied to a multiplier 12 and an edge detector 13 to form a sampling gate signal SG. Further, the other outputs of a red(R) tube 3 and a blue(B) tube 2 are calculated with the difference of the signal G0 at a subtractor 15 and a position shift signal REG is obtained. This signal is multiplied by the signal EDG, an error signal ER is obtained, and sampled for the section of the signal SG at a sampling hold circuit 16 to obtain a sample hold voltage SH. The bias of the deflection current is changed repetitively in response to this voltage for the automatic adjustment of registration.

Inventor: NAKAMOTO AKIRA
IPC: F16K15/02
Filed: 1985-01-30
Abstract: PURPOSE:To reduce the pulsation of the mobile phase flow rate with a simple construction, by making the pressure drop range on the inlet side of a resistance tube generated at the start of suction of a plunger pump less than the pressure drop range on the inlet and outlet sides due to the resistance tube during the discharge process of the pump. CONSTITUTION:Discharge is done at a specified speed while suction is done at a higher speed by operation of a plunger of a plunger pump 3 in a high-speed liquid chromatograph 1. A first damper 14, a resistance tube 15 and a second damper 16 are interposed in a mobile phase passage between a pressure sensor 6 and a sample injector section 7 sequentially from the sensor 6 side. Then, the rate of change in the volume of the damper 14 and the resistance rate of the resistance tube 3 are so arranged that the pressure drop range on the inlet side of the resistance tube 15 when the drop is caused depending on the amount of reverse mobile phase running up to the closure of a check valve is made less than the pressure difference between the inlet and outlet sides of the resistance tube 3 during the discharge process of the damper 14 immediately after the start of suction with the pump 3. Thus, the pulsation of the mobile phase flow rate is reduced with a simple construction to such an extent as not to affect the base line of a highly sensitive differential refractometer/detector or an electrochemical detector.
