Title: Automatic screw fastening device
Inventor: ONDA NOBUHIKO
IPC: B23P19/06
Filed: 1989-03-16
Abstract: PURPOSE:To improve the efficiency for automatic screw fastening by providing a spacer for forming a gap between a sleeve and screw feeding part at the screw setting time, in an automatic screw fastening device where the rotating tool of an air driver, etc., are used. CONSTITUTION:In the case of setting a screw 100 to a bit 7, a gap 32 is formed between a sleeve 11 and screw feeding part 16, when a spacer 31 is abutted on the screw feeding part 16. When the screw 100 setting is started in this state, the air blown out of a blowout port 20 blows up a screw head part 101 and the one part is flown to the external part from the gap 32. In this case, if the flowout area is taken larger than the gap of the screw head part 101 and sleeve 11, the air is flown more to the gap 31 of smaller resistance. So, the air amount flowed into a suction part 6 is reduced, the screw 100 stops vibrating and it can be set by being engaged with the bit 7 surely and quickly.

Title: Light emission electron tube
Inventor: UETSUKI TADAO
IPC: H01J63/08
Filed: 1985-03-25
Abstract: PURPOSE:To prevent droppage of light emission efficiency and accumulated ionization by integrating the cathode, the anode and the grid thereby facilitating to maintain constant the interval. CONSTITUTION:A doughnut type first insulator 10a is fixed to the opposite ends of a thermionic emission cathode rod 2 then a tubular meshed anode 3 for passing electrons is secured to the outercircumference. While a doughnut type insulator 10b is fixed to the opposite ends of anode and a tubular meshed grid 7 is secured to the outercircumference. The distance betweean the cathode 2 and anode 3 is formed shorter than the average free stroke of electron. With such arrangement, the interval between cathode/anode or anode/grid can be maintained constant easily resulting in a light emission electron tube where droppage of light emission efficiency or accumulated ionization can be prevented.

Title: Parallel synchronization circuit for atm cell
Inventor: YAMAMOTO KYOKO
IPC: H04L12/28
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To prevent a scale of a decode circuit from being increased even when a parallel expansion number is increased by devising a header assignment method in the case of transition from a hunting state to a preliminary synchronization state so as to impose a load on a 53-base counter thereby simplifying the circuit. SOLUTION: In the case that a protection circuit 4 discriminates a hunting state H and either of two full expansion CRC arithmetic circuits 2, 3 detects a header in this parallel synchronization circuit, a 53-base counter 5 is loaded. A load value selection circuit 6 loads '1' when the header indicates a 1st parallel value P1 or '27' when the header indicates a 2nd parallel value P2 respectively to the 53-base counter 5. The 53-base counter 5 runs freely. When the header normally takes a 53-byte period, each header is periodically repeated such that a succeeding header is detected as a 2nd parallel value P2 with a count '26' and a header next to the succeeding header is detected as a 1st parallel value P1 with a count '53'.

IPC: F16J15/34
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To prevent a pressure increase in a seal box, and reduce a loss in motive power by turning of fluid by arranging turning preventive plates in the almost radial direction of a rotary shaft in the seal box. SOLUTION: Four turing preventive plates 2 are installed in the radial direction on a side wall in a seal box 1. A required process is only to install the preventive plates 2 by one or more sheets.

Abstract: PURPOSE:To provide a compact and simple structure where the switch operation of a liquid crystal display clock is conducted through a winding crown operation by setting a cam means turning coaxially with an external operation member, and a terminal is allowed to touch a spring portion through the swing movement of a switch lever. CONSTITUTION:A cam la is turned coaxially with an external operation member, a switch lever 2, having two springs 2a, 2b, is engaged with the cam 1a intermittently as the cam 1a turns so as to swing in a plane. A first and a second switch terminals are set so as to touch the springs 2a, 2b through the swing of the lever 2. When the lever 2 is not engaged with the cam 1a, the lever 2 is positioned by springs 2a, 2b. When the lever 2 is turned by the operation member so that one side spring is connected to the switch terminal, the other side spring acts as a returning spring returning the switch lever 2 to the original position. Thereby, it is possible to provide a compact and simple structure where all switch operations can be conducted through winding crown operations using the external operation member by constructing the simple structure of just one component, the lever 2.

IPC: H03M5/04
Filed: 1988-03-18
Abstract: PURPOSE:To attain low speed input data, to prevent a CMI encoding error and to maintain a normal phase relation by providing a CMI code forming part, an n-any ring counter, a CMI signal speed converting part, a 2n-any ring counter and a CMI signal parallel/serial converting part. CONSTITUTION:The CMI code forming part A, at the time of encoding the input data, divides to the two strings of a pre-bit and a post-bit. The speed converting part B respectively punches the signals of the two strings by the 1/nXF0 clocks of (n) strings generated based on the (f0) clock of an input in the n-any ring counter E to have the low speed and output the CMI signals of 2n strings. The signal parallel/serial converting part C reads the CMI signal of the 2n strings by the clocks of the 2n strings generated by the 2n-any ring counter G based on a 2f0 clock F. By such a constitution, the CMI encoding error can be prevented by the low speed input data, and even when a phase collapses at the time of applying a power source or by a clock tooth coming-off input, it is automatically reset to maintain the normal phase relation.
