Title: Production of diamine
Inventor: TOKUDA YOSHIHIRO
IPC: C07C209/82
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound industrially useful as a raw material for various polyamides and polyurethanes by subjecting a dialdehyde compound to a reductive amination reaction in the presence of a hydrogenation catalyst, hydrogen and ammonia and/or an amine, adding a specific sulfur-containing compound to the obtained crude reaction solution, and subsequently distilling the reaction solution to purify the reaction product. SOLUTION: This method for producing a diamine comprises subjecting a 8-12C dialdehyde (e.g. butanedialdehyde) as a raw material to a reductive amination reaction in the presence of a hydrogenation catalyst (e.g. Raney nickel catalyst), hydrogen, and ammonia and/or an amine, adding a compound containing a sulfur atom having a lone electron pair (e.g. di-n-dodecylsulfide) to the obtained crude reaction solution, before heated at a temperature above 120-150 deg.C, stirring the mixture at a lower temperature than the highly boiling point of the mixture for several min to several hr, and subsequently distilling and purifying the reaction product. The compound containing the sulfur atom having the long electron pair is used in an amount of 10-1000 ppm based on the weight of the objective compound contained in the crude reaction solution.

Title: Rope tensioner
Inventor: TAKAMORI SHIGERU
IPC: F16G11/12
Filed: 1987-06-24
Abstract: PURPOSE:To judge on whether impact face of more than the specified value is added to a rope tensioner and a rope or not in an easy manner by making a dent of the rope due to the impact force so as to be left behind on the peripheral surface of a check member of the tensioner of a parent rope engaging a lifeline at high ground work. CONSTITUTION:When impact force is added to a rope R as a parent rope by an operator's fall or the like during operation at an elevated spot, it is crossly stretched between a pulley 2 and a check member 5 being externally fitted in a rope guide member 4, so that the said impact force is transmitted to the pulley 2 and the check member 5 as almost radial impact force. Consequently, the rope R comes to be impactly pressed to the outer circumference of the check member 5, and since the check member 5 is made of soft synthetic resin, a dent of the rope R is formed on the outer circumference of the check member 5 by dint of the impact force. That is to say, if a fact that whether the dent is put on the outer circumference of the check member 5 or not is checked, whether the impact force is added to a rope tensioner and the rope R itself or not is judged and, what is more, whether reuse is possible or not can be easily known.

CONSTITUTION:A sample 104 is irradiated with X-rays radiated from an X-ray source 101 through a zone plate 102 and a pin hole 103. The X-rays transmitted through the sample 104 are image-picked on the image pickup plate 106 consisting of the photocondcutor film and the electrode of the high transmission factor through a zone plate 105. The probe is brought into contact with the image pickup plate 106 by the energizing force of a laser beam from a laser light source 112, which is made incident on a cantilever 108. AC voltage from a voltage impressing device 131 is impressed on the space between the electrode of the image pickup plate 106 and the probe 107 through the cantilever 108, and flowing AC current is measured in a current measuring device 132. The intensity of the X-rays which are made incident on the image pickup plate 106 is obtained.

Abstract: PURPOSE:To prevent frequency characteristics, linearity, etc., from deteriorating and to eliminate beat interference and an inversion phenomenon with regard to a dubbing system for color video signals, by mixing a low-frequency converted chrominance signal and luminance signal to be frequency-modulated and by recording the mixture direct on a recording medium. CONSTITUTION:A color video signal from input terminal 1 is processed in the normal method to obtain a frequency-division multiplex signal, which is recorded on recording medium A. From this recording medium A (A'), the above-mentioned frequency-division multiplex signal is reproduced by reproducing head 12 and passed through low-pass filter 23 to obtain a low-frequency converted chrominance signal, which is level-adjusted and then applied to one input terminal of mixer 25. Further, a luminance signal to be frequency-modulated is obtained from the above- mentioned reproduced signal and the compensation of frequency deterioration, averaging of upper and lower side-band waves, compensation of the frequency decreased of a carrier component, and removal of fluctuations of amplitude are carried out to record on recording medium B the output of mixer 25 applied to the other three inputs mixer 25. By such a dubbing system, the occurrence of an inversion phenomenon can be prevented, frequency characteristics, pulse characteristics and linearity is improved and beat interference is also reduced.

IPC: G06F12/08
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To effectively hold data of top priority which are hit at long intervals in the cache memory. SOLUTION: The cache memory 10 holds a specific amount of sequentially accessed data in its 1st area 12, a specific amount of the sequentially accessed data in its 2nd area, and a specific amount of data on data numbers hit in the 2nd area in its 3rd area respectively. In the respective areas 12, 13, and 14, the oldest used data are automatically deleted, When a system generates a request to access a data block, retrieval is carried out to find whether or not its data or data number is stored in the area 12, 13, or 14. Data which are hit at short intervals are held in the 1st area 12 and data which are hit at long intervals are held in the 2nd area 14 respectively. In the 2nd area 13, only the data numbers are held, so many data numbers can be held with small storage capacity.  This cache memory allows data of high priority which are hit at long intervals have resistance to data of low priority which form a long sequence.

IPC: G11B17/028
Filed: 1980-11-14
Abstract: PURPOSE: To load and unload a disk securely and easily by installing a spring which presses the disk under a hub and by enabling a yoke, which is attracted by the magnet of a spindle, to move up and down with a handle rotating around a fixed shaft.  
     CONSTITUTION: An annular ring 6 under a hub 8 constituting a hub assembly 4 is pressed down by a spring 7 to be locked with an annular ring 11. When the hub 4 is mounted on the center pole 12 of a spindle 1 having a magnet 3 in the center, the magnet 3 attracts the yoke 5 of the hub 4 to press a disk 2 with the spring 7. For unloading the disk 2, on the other hand, both the ends of a handle 9 rotating around the shaft 10 of a hub 8 are only drawn up to move yokes 5 suspended on the pawl parts of the handle 9, thereby separating the hub 4 from the magnet 3 easily. Consequently, pressing force to the disk is uniformed to secure loading, and unloading is achieved easily with small force.

Filed: 1977-12-27
Abstract: PURPOSE:To realize application to the control of a distribution line by varying a phase or frequency at a constant period, by preventing the lowering of a level due to crosstalk occurring during transmission from continuing for a long time, and by making it possible to transmit a control signal which enables invariably-definite control. CONSTITUTION:When signal (c) exists which is generated due to crosstalk from any other line, received signal (d) has the waveform equivalent to composite one between signals (b) and (c). The phase of signal (b) is switched at period (t1), and that of signal (c) is at period (t2), so that the time when the reception level is detection level Ls will not become longer  than either (t1) or (t2). Therefore, the time when discrimination signal (e) of receiver circuit 21 is OFF becomes longer than either (t1) or (t2) a few times and control state signal (f), the output of holding circuit 22 with holding time T longer than either (t1) or (t2) is outputted, without discontinuity, for the period when control is required, so that definite control will be carried out  invariably.
