Title: Pneumatic tire for agriculture
Inventor: SHIMIZU NAOAKI
IPC: B60B15/02
Filed: 1989-02-03
Abstract: PURPOSE:To enable the tractive force, mud-discharging performance, and buoyancy to be compatible with each other, in a plurality of blades formed on a plurality of lugs arranged on the tread part, by intersecting both radial directional inner and outer side parts at specific angles which are different to each other to the radial directional line. CONSTITUTION:On the outer circumference of the tread part 2 in a tire 1, a plurality of lugs 3 are extended in the radial direction at equal spaces in the circumferential direction. And, at least one every other lug of respective lugs 3, a pair of blades 5 are integrally formed. In this case, the radial directional outer side part 10 of each blade 5 is made to cross at an angle B of intersection of 15 deg. to 40 deg. to the radial directional line R. And the radial directional inside part 11 of each blade 5 is made to cross at an angle D of intersection greater than the above intersection angle B by 10 deg. to 30 deg.. Further, the radial directional outside part 10 and the radial directional inside part 11 are bent at the boundary E. Thus, the tractive force at the time of forward movement, and the mud-discharging performance and buoyancy at the time of reverse movement can be compatibly enhanced.

Title: Reduction of interference in discrete multi-tone (dmt)-based communication system
Inventor: DAGDEVIREN NURI R
IPC: H04J11/00
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To provide an asynchronous digital subscriber loop(ADSL), based on a discrete multi-tone system having an upper stream channel and a downstream channel which are separated but are adjacent to each other. SOLUTION: During a training stage for ADSL connection, an ADSL discrete multi-tone(DMT) transmitter first sends a position location signal to the ADSL end point of a remote opposite party so as to determine a round propagation delay. During the succeeding communication steps, the ADSL transmitter synchronizes the transmission of a DMT symbol with a reference clock. Furthermore, the patrol extension of each DMT symbol increases as a function of the round propagation delay.

Title: Image forming device
Inventor: HIRAHATA SHINICHI
IPC: G03G15/047
Filed: 1991-02-20
Abstract: PURPOSE:To provide image forming device capable of reducing the unevenness of image density caused by the dispersion of exposure on the surface of photosensitive paper generated by the roughness/fineness of an exposure pitch. CONSTITUTION:In a wet-type color image forming device, an auxiliary exposure device 1 is arranged in the rear of an exposure device 42 and in front of a prewetting device 43. Therefore, in sheet like photosensitive paper 20 electrostatic charge is imparted by a corona electrifier 41 firstly, electrostatic latent image is formed by an exposure device 42. Surface electrical potential after exposure at this time is higher than prescribed surface electrical potential before development, thereafter, is lowered to the prescribed surface electrical potential by irradiating light outputted from the auxiliary exposure device 1 to the sheet like photosensitive paper 20 and exposing it uniformly. Thus, the dispersion of the surface electrical potential of the photosensitive paper generated by the roughness/fineness of the exposure pitch is reduced.

Title: Amplitude extracting circuit of digital data reproduced signal
Inventor: SAKAGAMI HIROFUMI
IPC: G11B20/10
Filed: 1984-02-15
Abstract: PURPOSE:To discriminate the quality of a reproduced signal and abnormality of a disk, by introducing a reference signal based on the inverting interval of the reproduced signal. CONSTITUTION:Digital signals and clocks are detected from reproduced signals, whose inverting interval is 3T-11T, at a detecting circuit 2 and a counter 3 measures the inverting period of the signals and supplies a prescribed signal to decoders 4-7 when inversion occurs. Each decoder 4-7 output pulses at times when 1.5T, 5.5T, 3T, and 11T have passed after the signal is inverted, respectively. By means of a pulse from an OR circuit 8, an S/H circuit 9 outputs a signal H of the top value or bottom value of the reproduced signals at the inverting intervals of 3T and 11T. Moreover, a decision circuit 10 decides each period including the inverting intervals 3T and 11T, signal level, top value, and bottom value, and gives corresponding pulses to S/H circuits 11-14. As a result, each circuit 11-14 outputs each signal of the bottom value and top value at the inverting intervals of 3T and 11T as reference signals regarding the signal H.

The plural steel wires are stranded to form the stranded wire and the wire is coated with the synthetic resin 4 to >=4mum film thickness, by which the holding member 1 is made into out of roundness as a whole and is brought into uniform contact with the lens. The knot strength at the time of fixing the member to the frame body is improved and the loosening of the knot part is obviated. As a result, the holding power of the lens is exceedingly improved and the life is greatly prolonged.
