Title: Method and apparatus for ensuring bit synchronization of data block
Inventor: MANFUREETO TASUTO
IPC: H04L7/033
Filed: 1987-08-06
Abstract: For synchronizing a data block in a receiver, there are transmitted consecutively and prior to the data block: a first bit sequence of alternating "0" and "1" levels for determining the bit clock and a second bit sequence for determining the block synchronization by correlation. In known methods of determining the bit clock, the phase range of the individual bits of the received digital signal is divided into sub-intervals and the phase position of the bit clock is determined on account of the number of edges in these sub-intervals. In order to avoid fading and phase jitter having a detrimental effect on the bit synchronism, more specifically when transmitting through radio transmission links, N-phase-shifted clocks having the same clock frequency are generated in the receiver by means of which the first bit sequence is sampled. The clock for which the number of sample-value changes of the first bit sequence is established as having a predeterminable minimum value during a predeterminable time-interval is utilized as the phase synchronous bit clock.

Title: Driving circuit of laser diode
Inventor: KIMURA SHIYUUJI
IPC: H01S5/068
Filed: 1982-11-08
Abstract: PURPOSE:To make the output from a laser diode constant regardless of a change of junction temperature by a method wherein a reverse bias current supply circuit is provided. CONSTITUTION:A reverse bias current supply circuit G to control a laser diode driving current IF as a sum of a signal current IP and a bias current IB is provided. In the circuit G supplying a reverse bias current IR, a series circuit of a resistor R1 and a transistor Q is connected to a laser diode LD in parallel. A Zener diode D and a resistor R maintain the base potential of the transistor Q as well as the reverse bias current IR to be constant. The stability of base potential of the transistor Q is excellent and the temperature fluctuation of the reverse bias current IR is almost none since the temperature fluctuation of the reverse directional voltage of the Zener diode is very little within broad specific region. Therefore a constant reverse bias current IR may be supplied from an emitter of the transistor Q. Resultantly, even if the same signal current as the cases of the intermediate temperature T2 and the high temperature T3 is supplied, an output value PO may be made constant by means of setting up a bias current to be IB1 since the reverse bias current IR may be supplied even at a low temperature such as T1 of the junction temperature.

Title: Shrinkable film for label
Inventor: EZAWA HIROSHI
IPC: B29K23/00
Filed: 1985-09-06
Abstract: PURPOSE:To obtain a shrinkable film, prominent in a resistance to heat, transparency and mechanical property upon bonding the film by employing specified copolymer of ethylene-propylene. CONSTITUTION:A sheet is formed by a composition consisting of 100 weight parts of the copolymer of polyprophlene, containing 2-10wt% of ethylene, and 0-50 weight parts of the monomer of polypropylene. The sheet is oriented into one direction after preheating the sheet to a temperature lower than the melting point of the copolymer of polypropylene. The shrinkage factor in the direction of the orientation of the film after dipping into an oil bath having the temperature of 150 deg.C for one minute is 40-85% while in the shrinkage factor in a direction, orthogonal to the direction of orientation, is 15% or less. In case the content of ethylene is up to 2wt%, the temper ature width of the shrinkage of the oriented film is narrow and it is hard to make the whole periphery of a coated bottle beautiful when hot air is blown against the film. In case it exceeds 10wt%, the rigidity of the film is deteriorated and loss is generated frequently when the film is bonded onto a glass bottle or the resistance to heat of the film is deteriorated. n case the content of polypropylene exceeds 50 weight parts, the temperature width of the shrinkage of the oriented film becomes narrow and product loss due to poor appearance upon bonding it onto the glass bottle is generated frequently.

Title: Manufacture of circuit board covered with thin copper foil
Inventor: KAJIWARA SHOICHIRO
IPC: H05K3/06
Filed: 1989-07-28
Abstract: PURPOSE:To obtain a circuit board which is covered with thin copper foil, extremely high in thickness accuracy, excellent in rust preventive effect, and high in gloss and commercial value by performing finish etching or chemical polishing after performing etching with a cupric chloride/hydrochloric acid solution at an extremely low speed. CONSTITUTION:The entire surface of copper foil is first etched with a cupric chloride/ hydrochloric acid solution to remove the 25-90% of the original thickness of the copper foil and the fluctuation of the thickness of the remaining foil is suppressed to <=+ or -1.0mum against a desired thickness. The etching speed is sharply reduced to a range of 0.01-0.3mum/sec and, at the same time, the dependency of the etching on the concentration of the etching chemical and etching temperature is lowered. When the etching speed is faster than 0.3/m/sec, the difference in etching quantity becomes larger due to differences in etching time, concentration, temperature, etc., which are smaller than an etching condition controllable range. After the remaining copper foil is etched so that the thickness of the remaining foil can become thicker than the desired thickness by 1-4mum, finish etching or chemical polishing is performed by using a hydrogen peroxide/sulfuric acid solution.
