Title: Improvements in pipe couplings
Inventor: PITT ANGUS RAYFIELD
IPC: F16L19/075
Filed: 1956-01-05
Abstract: 801,631. Pipe joints. DOWTY EQUIPMENT, Ltd. Jan. 4, 1957 [Jan. 5, 1956], No. 463/56. Class 99(1). A collar 3 secured to a pipe 1 projects beyond the pipe end, a collar 7 is secured on a pipe 2 so as to leave a short portion of the pipe end projecting back, a sleeve 11 fits around the collars, and a rubber &c. sealing ring 13 is compressed in an annular gap between the collars, the sleeve and the projecting pipe end. The collars 3, 7 and the pipe ends 1, 2 are made of stainless steel and are brazed to each other by the insertion of pellets of brazing material in recesses 6, 8 in the collars respectively which melt and flow around the inner face of collars and pipes when heated, e.g., by electrical induction. The collar 3 has a central external screw thread 4 and a hexagonal part 5. The parts are clamped together by a nut 9 integral with the sleeve 11 and engaging the screw thread 4. The collars are secured to the pipe ends so that when the end of the pipe 2 is inserted into collar 3 and contacts the end of pipe 1 a small gap is left at 12 and the sealing ring 13 is compressed in an axial direction when the joint is assembled. If low pressure fluids are conveyed, the fastenings may be made less mechanically strong and the sleeve may be a separate part or alternatively secured to either collar. For this modification the projection of pipe 2 from collar 7 may be reduced so that the collars abut on assembly without the presence of a sealing ring, and in this case the ring could be of square cross-section, the radial depth being approximately that of each of the collars.

Title: Improvements in or relating to typographical composing machines
IPC: B41B11/18
Filed: 1950-01-12
Abstract: 685,132. Type-bar-making machines. LINOTYPE & MACHINERY, Ltd., SCOTT, R. H., and HAYWARD, A. S. Jan. 10, 1951 [Jan. 12, 1950], No. 828/50. Class 100 (iii). Escapements.-In a typographical composing machine such as known under the Registered Trade Mark " Linotype," mechanism for controlling the delivery, one at a time from the storage magazine, of spacebands each having a slide formed with a recessed side surface and a slot at the extreme lower end, and an upper wedge-shaped section provided with projecting ears by which the spaceband is guided into a delivery shoot, comprises a fixed stop for engaging the recessed side surface of the foremost spaceband to maintain it in an inclined position, and means for lifting the lower end of the slide to disengage its recessed side surface from the fixed stop and allow the spaceband to swing into vertical position when it is free to fall into the shoot. The upper end of the foremost spaceband Y, Figs. 1 and 2, rests against a cover plate HI of the shoot H. A finger 3 behind a fixed stop 2 engages the recess Y4 in the spaceband slide Y3. On operation of a spaceband key, the finger 3 is lowered by means of an escapement lever 5, so that the spaceband swings forward until the stop 2 engages the recess, while the finger 3 is within the slot Y5 in the slide. The finger 3 is then raised, thereby raising the slide Y3 until the slot Y5 is aligned with the stop 2, so that the spaceband swings into vertical position and falls into the shoot, the ears Y2 now being aligned with grooves H2 in the shoot, and the slide Y3 also returning to its lower, unexpanded position. In another form, the stop is integral with or connected to the lower guiding rail 1, and has in its lower face a recess to accommodate a horizontal finger movable vertically similarly to the finger 3, to similarly release the spaceband, said finger engaging first the recessed face and then the lower end of the slide. If the spaceband is incorrectly located in the magazine, with the non-recessed surface against the horizontal finger, it will not advance sufficiently when the latter is lowered to be raised by it, and will not be released.

Title: Semiconductor memory device
Inventor: HIDA YOICHI
IPC: G11C11/407
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To assure reliability of gate insulation film of an access transistor of a DRAM(Dynamic Random Access Memory) of the word line non-voltage boosting/word line negative voltage system and a word line driver section transistor. SOLUTION: An intermediate voltage for precharging is generated using an array voltage which is lower than the power supply voltage and an array voltage is transmitted as a sense amplifier drive signal to a sense amplifier(SA). A high level potential of bit lines (BL, /BL) for reading high level data is an array voltage level which is lower than the power supply voltage and a voltage difference between the non-selected word line after a negative voltage (-VS) is applied to the non-selected word line and the bit line from which the high level data is read is equal to the power supply voltage level which prevents application of excessive voltage to the gate insulation film of the access transistor.  Moreover, a high level data of the gate of word driver transistors (4ac, 4bc) is equal to an array voltage level to prevent application of the voltage higher than the power supply voltage to the gate insulation film.

Title: New conductive bipolar element pattern which reflects electromagnetic wave of frequency in specific range, and frequency selective electromagnetic wave shielding material comprising it
Inventor: TAKASO TOSHIKI
IPC: H05K9/00
Filed: 1998-01-05
Abstract: PROBLEM TO BE SOLVED: To provide a conductive pattern wherein communication wave is selectively reflected, sufficient electromagnetic wave shielding is provided, and excellent perspective characteristic is provided, by insulating each conductive bipolar element and allowing adjoining conductive bipolar elements to keep each other as close as possible. SOLUTION: The dimension of a conductive bipolar element is decided depending on a frequency which is to be shielded. Adjoining conductive bipolar elements are preferred to close each other. This enhances shielding power against electromagnetic wave. Further, adjoining conductive bipolar elements are preferred to keep each other as close as possible. However, the conductive bipolar elements should not contact each other. In short, the conductive bipolar elements should be electrically insulated from each other. If the conductive bipolar elements are electrically conducted each other, the resonance characteristics of conductive bipolar element pattern changes, thereby the frequency region of electromagnetic wave which can be reflected changes.
