Inventor: FURUKAWA HIROSHI
IPC: H01M50/541
Filed: 1983-09-12
Abstract: PURPOSE:To reduce the weight and the cost of a storage battery by slanting or curving the lug of a side plate relative to a strap. CONSTITUTION:After a metallic mold 7 having a projection 11 for curving the lug of a side plate is placed on the opposite side to an electrode pole, a molten lead alloy 9 is poured into the metallic mold 7. After that, the ends of the plate lugs of a plate group are inserted into the metallic mold 7. As a result, the lug 5 of a side plate 3 which is located on the opposite side to the electrode pole and heated by the molten lead alloy is curved by the projection 11 and a strap is formed. By decreasing the length of the lug 6 of the side plate 3 from (l) to (L'), the dimension becomes smaller by (a) thereby enabling saving of lead and reduction of the weight to be achieved.

Title: Laser diode
Inventor: HANEDA MAKOTO
IPC: H01S5/02385
Filed: 1981-10-23
Abstract: PURPOSE:To allow to obtain an excellent transversal mode characteristic and a far view image, by slightly projecting one end surface which emits the laser light of a chip fixed on the upper surface of a submount with a solder from the side surface of the submount. CONSTITUTION:The laser diode chip 4 is fixed on a mount 2 with the solder 5 in the state that the emitting part which emits the laser light 6 is in access to the submount 2. The end surface of this chip 4 having one side emitting surface is projected from one side surface of the submount 2 by (b). The value b is several mum-several tenmum. Thus, even when the solder 5 overflows, it is concealed under the lower surface of the chip 4 resulting in the porjection thereof to the side of emiting surface by fixing the chip 4. Thereby, since the laser light does not reflect on the solder bump and the upper surface of the mount 2,  the transversal mode defective of a laser light does not generate. Further, since the laser light is not interfered by the bump, the turbulence of a far view image does not generate.

IPC: H01J29/07
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a color selecting mechanism for cathode-ray tube in which a grid element is never twisted, and stripe unevenness is hardly caused in an image by setting the tension of a color selecting electrode thin plate before blackening treatment to a specified value or lower, and blackening the thin plate so that the tension change of the tin plate before and after blackening treatment is within a specified range. SOLUTION: A color selecting mechanism 10 is thermally treated (called also blackening treatment) in order to remove a working distortion in a process before welding a spring 9 to a spring holder 8 after welding a color selecting electrode thin plate 4 to a frame 11. In this color selecting mechanism 10, when the thin plate 4 is laid on the frame 11 before blackening, the tension of the color selecting electrode thin plate 4 is set less than 700 N/mm<2> , and the tension difference before and after the blackening treatment, or [tension before blackening-tension after blackening] is set to form -100 to 200 N/mm<2> . The color selecting mechanism 10 having such a structure hardly causes a stripe unevenness in an image since the grid 7 of the color selecting electrode thin plate 4 is hardly twisted.

Title: Luminance signal processing circuit
Inventor: SHIRAI SANZO
IPC: H04N9/78
Filed: 1989-06-30
Abstract: PURPOSE:To simplify the luminance signal processing circuit by constituting a non-correlative component emphasizing circuit at the time of recording and constituting a line correlative noise reduction circuit at the time of reproducing while using the 1H delay circuit of a 3-line logical comb filter. CONSTITUTION:At the time of recording, a non-correlative minute component, which amplitude is limited, is conducted from a first limiter 6 and inputted to a first adder circuit 10 after attenuation in a K-fold circuit 7. Since a first delay circuit 5 inputs the luminance signal of a comb-shaped characteristic matching timing with the non-correlative fine attenuated component to the first adder circuit 10, the luminance signal of the emphasized non-correlative fine component is conducted to a third terminal T3. At the time of reproducing, a third delay circuit 17 delays the 1H delay signal and matches the timing with the output of the second limiter. Then, the output is inputted to a first subtracting circuit 27. Accordingly, the reproduced luminance signal, for which noise components such as a cross color component or a residual color component, etc., are removed, is conducted from this first subtracting circuit 27 to a fifth terminal T5.

Title: Data way reconstitution system
Inventor: KOUSAKA TAKASHI
IPC: H04L12/437
Filed: 1982-09-29
Abstract: PURPOSE:To reconstitute a data way at a high speed by sending the state signal of one station to its adjacent station in response to a circuit reconstitution start signal, and changing states of connections with a circuit on the basis of a state signal from the adjacent station in response to a circuit reconstitution end signal. CONSTITUTION:When a monitor station starts reconstituting operation in a dual loop data way ststem, a start command is outputted to the circuit 1. If a fault occurs in a station (k), the start command does not arrives to the station (k). Stations (i) and (j) receive the start command and output state answer signals to their upstream stations through the circuit 2 respectively. When the monitor station outputs an end command to the circuit 1, each station decides on whether the circuit connected to the station is placed in loop-back mode or forward mode on the basis of the state answer signal from the downstream station.
