Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To provide a camera equipped with an accurate range-finding device which can be miniaturized and is free from erroneous range-finding due to heat generation by a stroboscopic device by providing heat insulating material to prevent heat generated from the stroboscopic device from being transmitted to the range-finding device between the stroboscopic device and the range-finding device. SOLUTION: As for a front cover 1, the front of a camera is covered with a front cover 1c, and the housing part of the stroboscopic device is formed by the front covers 1a and 1b, then the front of the stroboscopic device is opened. An AF module 8 functioning as the range-finding device is juxtaposed to a side where the front cover 1a of the stroboscopic device is provided. The heat insulating material 9 functioning as a heat insulating means is made to intervene between the module 8 and the front cover 1a. Since the material 9 intervenes, the heat generated from the stroboscopic device is prevented from being transmitted to the module 8 side. Thus, the range-finding device and the stroboscopic device are arranged proximately to each other.

Abstract: PURPOSE:To provide a printer simple in construction and capable of making illegible nagative patterns left on an ink ribbon used for recording to observe secrecy of the printed contents, wherein an ink carrier used for transferring is brought into frictional contact with a grindstone form roller. CONSTITUTION:The grindstone form roller 5 having a roughness sufficient for scraping off a solid ink on an ink ribbon is placed in contact with the surface of the solid ink on the ink ribbon. Whne the roller 5 is rotated at a circumferential velocity different from the feeding velocity of the ink ribbon, the surface of the ink is scratched due to a rubbing or scraping action or the like, whereby the negative patterns left on the ink ribbon after transfer recording can be converted into illegible patterns. The roughness of the grindstone is preferably set to be approximately equal to the thickness of the solid ink on the ink carrier. A roller 6 is preferably faced to the roller 5, and particularly by setting the hardness of the roller 6 to be low, adhesion between the roller 5 and the ink ribbon 3 is enhanced, and the solid ink can be completely released from the ink ribbon 3.

Title: High-voltage digital signal output circuit
Inventor: TANAKA AKIO
IPC: H03K19/0185
Filed: 1985-08-07
Abstract: PURPOSE:To obtain a high-voltage output circuit which has high dielectric strength and excellent and stable characteristics by connecting a Zener diode between a high-voltage side power source and the gate of a P channel field- effect transistor (FET). CONSTITUTION:When a signal input terminal VIN3 rises from L to H, VIN1 also rises from L to H to turn on Q1 and a drain connection point P2 falls below VDD by the Zener voltage VZ of the Zener diode D2 to turn on Q5. At this time, Q2 turns off, so the potential at P1 is VDD and both Q4 and Q6 turn off. At this time, Q3 is also turned off by VIN3, so a load capacitor CL is discharged and an output VOUT1 is VSS. When the VIN3 falls from H to L, VIN2 rises from L to H and the Q2 turns on; and the potential at the drain connection point P1 drops below the VDD by the Zener voltage VZ of a Zener diode D1, and the Q4 and Q6 turn on to charge the load capacity CL through the Q6, so that the potential VOUT1 is equal to the VDD.

Title: Charged-particle energy analyzer
Inventor: YAMAUCHI HIROSHI
IPC: H01J49/44
Filed: 1981-10-31
Abstract: PURPOSE:To correct the difference in the selecting energy level which is caused according to  the value of theta by preparing a conductor surface, which constitutes a low-pass filter, from a  resistance layer, giving an electric-potential gradient along the surface of the resistance layer,  and decreasing the electric-potential difference between a part of the resistance layer and a  facing grid as said part comes apart from the center of the resistance layer. CONSTITUTION:Since the incidence angle upon a low-pass filter is 1/2 of the emission angle of  electrons (or ions) discharged from a sample (S), the incidence angle becomes large as it comes  apart from the center of the surface of a resistance film 2. Therefore, in the figure, the angle  (theta) is larger than the angle (theta'). A lead wire 3 is made to penetrate the center of an insulating  body 1, and connected to the center point of the resistance film 2. An electric-potential difference is given between the lead wire 3, and conductor rings 4 connected to the outermost  periphery of the film 2. The film 2 is provided with an electric potential gradient sloping up  from the periphery to the center of the film 2. When the angle of the outermost periphery of  the film 2 seen from the position of the sample (S) is supposed to be (2thetao), the incidence angle  at the outermost periphery of the film 2 is (thetao). When the electric potentials of the center and  the outermost periphery of the film 2, respectively, are supposed to be (Vo) and (V) with  reference to that of a grid (G1), the influence of the slant incidence is compensated when the  relationship of V=Vocos thetao is satisfied.

Title: Pulse width modulating type d-a converter
Inventor: SATOU IKUO
IPC: H03K9/08
Filed: 1980-12-12
Abstract: PURPOSE:To make the accuracy of output at nonoverflow high, by applying a part of an overflow bias to a full scale output via a diode, at the overflow signal input. CONSTITUTION:Since a switch S3 turns off at nonoverflow, a pulse width modulation circuit 1 is grounded via a resistor R2 and a diode 13 back-biased. Thus, even if a switch S1 turns on with a pulse width modulation signal, the output can be picked up via a buffer amplifier 11 without voltage division at the resistor R2. At overflow, since the switch S3 turns on, an overflow bias VB appears at the output terminal of the diode 13 and is divided at the resistors R1, R2 and applied to a full scale bias VREF, allowing an output increasing the VREF by 10% to be picked up from the buffer amplifier 11.

Filed: 1991-07-16
Abstract: PURPOSE:To enable a report number which indicates a type of analysis and a series of numbers for the analysis to be printed on each page by updating a report number every time the analysis type changes and accumulating a series of numbers for each analysis every time the page changes CONSTITUTION:After initializing a variable REPORT and a variable PAGE to 1, analysis processing is initiated by a CPU. When the analysis processing is completed, printing processing is started for the completed analysis, which continues until printing for one page is completed. When the printing processing ends, values of variables REPORT and PAGE which store the report number and the page number are printed on a last line. When printing processing for one page is completed, a cutter 15 cuts a printing paper and then stores it in a stacker 17 by a paper-delivery roller 16. Then, the CPU counts up the variable PAGE and judges whether all printing processing are completed for one analysis. If all printing processing are not completed for one analysis, printing continues. On the other hand, if they are completed fully, the variable REPORT is counted up and the variable PAGE is initialized.
