Title: Shadow mask for color picture tube
Inventor: ITOU SHIYUUJI
IPC: H01J9/14
Filed: 1984-02-15
Abstract: PURPOSE:To make it possible to fix a shaped mask to a frame without causing any stress on its curved surface by providing plural protrusions to give the shaped mask support reference points on the edge face of the frame on the shaped mask side and by forming inwardly protruding points on the skirt of the shaped mask so that they will touch the frame. CONSTITUTION:A skirt 11a of a shaped mask 11 has an inwardly protruding point 11b. On the edge face of a frame 12 on the shaped mask side, four protrusions 12a, each having a semicircular tip, are formed on the longer sides near the corners of the frame 12. In this way, when the shaped mask is only fitted in the frame, the protrusion 11b touches the outside wall of the frame 12, and thus the horizontal position is maintained; and a portion of the shaped mask 11 corresponding to the protrusion 12a of the frame 12 is softly pushed by a pusher 15 through a spring 14, and thus the shaped mask 11 is maintained in its vertical position with respect to the frame 12. When the protrusion 11b is spot-welded to the frame 12, the applied pressure from the spot-welding causes no stress on the shaped mask.

Title: Counter device
Inventor: OBARA NAGAYOSHI
IPC: G11B27/17
Filed: 1984-02-15
Abstract: PURPOSE:To enable a normal operation of a tape counter even when a tape control signal is not being recorded by counting a reel pulse signal and a capstan signal, etc. when the reproducing control signal can not be obtained. CONSTITUTION:When a reproducing control signal outputted proportional to a tape travel length from a control head 4 is supplied, a drive pulse is generated from a microcomputer 5 and a tape counter 6 up/down counts according to a travel direction of the tape 3. This computer 5 is supplied a capstan signal corresponding to the number of revolution of a capstan 7 through the capstan 7. This signal is converted into a reproducing control signal and even when this control signal can not be obtained, the counter 6 performs a normal counting operation, thereby enabling the tape counter to operate normally even at a part where the tape control signal is not being recorded. In stead of the capstan signal, the use of the reel pulse proportional to the number of revolution of the reel can obtain the same result.

IPC: G01S7/22
Filed: 1988-02-05
Abstract: PURPOSE:To accurately read a scale in an easy-to-read state by displaying a parallel line cursor electrically and allowing the rotation and interval of the cursor to be varied. CONSTITUTION:A cursor operation circuit 12 is a circuit including a switch and a variable resistance for the display/nondisplay switching of the parallel line cursor and for varying the intervals of the straight scale of the parallel line cursor and supplies the necessary indication of the parallel line cursor to a cursor signal generating circuit 5 through knob operation. The cursor signal generated by the signal generating circuit 5 according to the indication is converted by an interface into a signal, which is inputted to a control circuit 7. The control circuit 7 sends a video signal for cursor display to a display and storage circuit 8. The storage circuit 8 outputs the video signal of the parallel cursor to a display composing circuit 9. The display composing circuit 9 puts the video signal of a radar echo and the video signal of the parallel line cursor together and outputs the composite signal to a display driving circuit 10 to drive the electron beam scanning of a cathode-ray tube 11 by parallel raster scanning, thereby displaying the parallel line cursor together with the radar echo from the target.

Abstract: PURPOSE:To treat impurity-introduction into the side walls of a groove and the inner circumference face of the base at a high speed and further, make it possible to introduce impurities into a semiconductor substrate at a uniform impurity concentration, by installing the semiconductor substrate in parallel to a thin plate-shaped plasma region having a dense, uniform ion electric current distribution. CONSTITUTION:An extensive plate-shaped plasma region 18 of high density is formed between a plasma beam source 10 and an electrode facing the above beam source by the effect of a magnetic field which is formed by: a plurality of focusing coils 26; a permanent magnet for an electrode facing its magnet which is installed at the rear of the electrode 12; and the permanent magnet 44 which is installed at the outlet of the plasma beam source 10.

The impurity ions collide with a semiconductor substrate 16 on a sample electrode 14 where a prescribed negative voltage is impressed to the facing electrode 12 and then, impurities are introduces into the side walls of a groove as well as the base. In such a case, as the inside of the vacuum chamber 22 is kept at a high vacuum 10<-3>-10<-4>Torr, the average free path of the impurity ions becomes large and then, the impurities are introduced into both side walls of the groove and the base having a large aspect ratio.

IPC: G03B27/53
Filed: 1989-02-03
Abstract: PURPOSE:To simplify constitution and to compose a displacement-free synthetic photograph by providing a loop forming stage between exposing stages and adjusting the loop to a fixed length according to the size of a print frame and the type of synthetic pattern. CONSTITUTION:A photosensitive material such as a color paper 2 is set to the 1st exposing stage 6 to print and expose an illustration. When an appropriate number of frames are printed and exposed at the 1st exposing stage 6, they are stored in the loop forming stage 23 to turn into a loop. The loop is set in the prescribed length according to the size of the frame and the synthetic pattern. After they turn into a loop of this length they are carried by frame to the exposing stages 6 and 7, which print and expose them. By maintaining the loop length at a prescribed one, the frame position is matched at the exposing stages 6 and 7. Consequently, it is unnecessary that the either of the exposing stages 6 and 7 is moved to match the frame position; therefore the constitution is simplified.

A negative electrode is made by punching a rolled lithium plate into a given dimension. Electrolyte is prepared by dissolving lithium perchlorate in a mixture solvent composed of equal volumes of propylene carbonate and 1,2-dimethoxyethane. A separator consisting of a nonwoven polypropylene fabric is impregnated with the above electrolyte. As shown by graph (A), this battery has a discharge voltage of about 1.5V and its discharge characteristic does not present two steps, indicating that it is interchangeable with an existing silver or mercury battery.

Title: Method for probing semiconductor integrated circuit device
Inventor: YOSHIDA HIROTO
IPC: H01L21/66
Filed: 1988-02-05
Abstract: PURPOSE:To reduce cost loss due to a defect, by probing characteristics of ripple removing coefficient as AC characteristics. CONSTITUTION:When a first DC voltage Vcc1 and a second DC voltage Vcc2 are applied from a DC voltage source 11 to a power supply terminal 2, a power supply Icc1 and Icc2 corresponding to respective DC voltages are measured by an amperemeter 10. When the first and second DC voltages Vcc1 and Vcc2 are kept constant, an Early voltage comparatively relates to the difference current  Icc between Icc1 and Icc2. On the other hand, the ripple removing coefficient is the difference current  Icc and it comparatively relates to the Early voltage. Therefore, the ripple removing coefficient as AC characteristics is checked by measuring the difference current  Icc of a measured integrated circuit device 1 by probing it (check of DC characteristics).
