Title: Timing generating circuit
Inventor: MATSUMOTO TETSUO
IPC: H03K5/13
Filed: 1982-04-19
Abstract: PURPOSE:To eliminate the dispersion in the leading of input pulses and the fluctuation, by detecting that a gate voltage of a power supply voltage MOSFET receiving the input pulse reaches a prescribed value and switching other MOSFEs from on to off. CONSTITUTION:When an input pulse phiIN rises to a high level, charge-up is done to a bootstrap capacitance CB through the MOSFETQ5. As a voltage of a node N1 rises, the MOSFETQ6 is turned on and the voltage of a node N2 rises. The gate voltage of the MOSFETQ5 rises with the self-bootstrap operation and the input pulse phiIN is given to the node N1 without causing any level loss. When the voltage of a node N2 exceeds a threshold voltage VTH of the MOSFETQ9, the MOSFETQ9 is switched on and the MOSFETQ7 is switched off. The node N2 is changed to a low level and the MOSFETsQ2, Q4 and Q5 are set off.

Filed: 1980-05-14
Abstract: PURPOSE:To easily manufacture a multifiber with superior transmitting characteristics at a low cost by melt-spinning a glass rod having a plurality of parallel holes regularly arranged in the axial direction. CONSTITUTION:Rodlike glass 21 having many holes 22 is immersed in a hot molten salt such as molten thallium nitrate to mutually diffuse Tl ion and Na or K ion in the glass through the hole surfaces. As a result, Tl<+> having larger ionic radius enters the position of Na<+> having smaller ionic radius in the glass to form a structure with higher filling degree, and the refractive index is increased. While evacuating the holes 22 of the glass rod 21, the rod 21 is melted by heating with heater 23, and it is spun optionally after closing the holes 22 by stretching the rod 21 downward in the axial direction. Thus, a multifiber with superior resolving power and transmittance is manufactured.

Filed: 1980-05-19
Abstract: PURPOSE: To shorten the period of kick-out work for a billet, and to make the titled kick-out  device possible to kick-out even a short billet and to increase the line speed, by constituting the  kick-out device so as to permit a kick-out lever to work one cycle against a reciprocal motion of a  cylinder which is a driving source for the kick-out motion.   
     CONSTITUTION: A kick-out device 10 is located on a side of a conveying table roller 11; each of  plural kick-out devices 10 is arranged between adjoining driving motors 15 of table rollers 11;  these kick-out devices 10 are synchronously operated. A work command is given to a driving  cylinder 28 in order to drive a working rod 29 so as to make a forward or a backward stroke;  hereby, a lever 23 makes a turn clockwise or counterclockwise so that a kick-out lever 17 makes a  reciprocal motion between a kick-out waiting position and a kick-out position during a one-way  turning motion of the lever 23; hereby, a billet 12 on a roller 11 is kicked out onto a skew roller  table 13. Accordingly, if the said working rod 29 mekes a recirporcal motion, the lever 17 makes  a reciprocal motion; hereupon the working distances of the cylinder 28 and the lever 17 are set to  a ratio 1:2. As a result, the frequency of command to be given to the cylinder 28 for kicking out a  billet 12 is only one command for making one forward or backward stroke, so that the frequency  of command is decreased to half of that of the conventional method and the frequency or kick-out  motion is doubled.

Title: Radio transmission method
Inventor: KAWABATA TAKASHI
IPC: H04B7/26
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To improve transmission efficiency and transmission equality by setting TDMA slot length to a length which corresponds to an information cell length, transmitting a system symbol with a slot that is immediately before a slot to be transmitted and making a mobile station use the slot and transmit information, except system information. SOLUTION: Information cells D1 to D5 and a system symbol S constitute a transmission burst. By the information cells, an information unit which includes sequence information that decomposes various data into fixed length or reassembles them is meant. The symbol S includes information for management, etc. Because TDMA slot length is set to a length corresponding to the information cell length, an arbitrary number of the information cells can continuously be transmitted without changing the slot structure. Transmission efficiency is k (the number of transmission information cells)/(1+k) and k≫1 and becomes high. Probability of not being able to receive is drastically reduced by resending the same information cell with a frame and the next frame, acquiring different receiving waves in different transmission environments, and synthesizing them.

Abstract: PURPOSE:To provide the device with the shallow base layer with high concentration to generate the high output with less noise by a method wherein the bipolar transistor is formed almost without the high temperature heat treatment. CONSTITUTION:The N<-> epitaxial layer 1b is laminated on the N<+> Si substrate 1a and  the P base thin layer 2 with the concentration of approximate 10<18> is formed by means  of the molecule beam epitaxial process at the low temperature of approximate 800 deg.C.  A base layer 2' is formed by etching a part of the layers 2 and 1 with hydrofluoric  acid and nitric acid. Then the base layer 2' is covered with the insulating layer 13  which is openend to form the poly Si layer 6 containing As of high concentration and  the insulating layer 14 by means of the CVD process at the low temperature of approximate 700 deg.C. Next, the insulating layer 13 on the base layer 2 is opened to be  implanted with ion forming the P<+> base connecting layer 8. The connecting layer 8 is  activated at the low temperature of 900 deg.C and As in the layer 6 is diffused to form the  N emitter layer 7. Then the insulating layer 14 is removed to mount the metallic electrode 9. In this constitution, the resistance may be remarkably reduced even if the base  width is narrower than that of the conventional device to decrease the concentration  around the base surface easily preventing the break down strength between the emitter  and the base from declining.

IPC: G11B5/127
Filed: 1984-04-02
Abstract: PURPOSE:To improve the recording/reproduction efficiency by using the 1st and 2nd cores of ferrormagnetic substance and a ferromagnetic thin film having higher saturated magnetic flux density than that of both cores and setting the thickness of said thin film at the value approximately equal to a gap formed between both cores. CONSTITUTION:A gap 23 is formed between cores 21 and 22 of ferromagnetic substance, and a thin film 25 made of a magnetic material such a Co-Zv ferrite, ''Sendust'', etc. having higher saturated magnetic flux than that of said cores 21 and 23 is formed between both cores. The thickness of the film 24 is set substantially equal to the physical size of the gap 23. As a result, a leakage magnetic field has no symmetrical form approximate to a semicircle like a normal ring head at a place near the gap 23. Then the leakage magnetic field is intensive in the direction vertical to a medium surface at the side of the film 25 having high permeability centering on the gap 23 and has an asymmetrical form. It is also possible to reduce the dipulse ratio of an isolated reproduction waveform as well as the peak shift amount.
