Patent JP-2000278126-A (JP)
Title: Pll circuit
Inventor: NAKAJIMA TAKESHI
IPC: H03L7/113
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain high phase accuracy and a fast response over a wide input fre quency range with a simple configuration. SOLUTION: The PLL circuit is provided with two kinds of phase comparators 1, 2 and a phase comparator with high precision is selected depending on the quantity of a phase difference between an input signal and an output of an oscillator 6 and an output of the selected phase comparator is given to a loop filter 5 so as to obtain high frequency accuacy and phase accuracy. Furthermore, the input signal or a signal frequency-dividing the input signal is used for a signal source of a sampling frequency of the loop filter 5 so as to allow a characteristic frequency of the loop filter to track the increase/decrease in the frequency of the input signal so as to obtain a fast response over a wide frequency band.  Moreover, a numerically controlled oscillator 6 is used to attain a continuous and fast frequency change over a wide input frequency range so as to obtain an excellent transient response. In the case that a phase difference between the input signal and the oscillator output is considerably large, that is the PLL circuit is unlocked, the tracking speed when the frequency of the input signal is largely changed can be enhanced by setting a detected input signal frequency to an output frequency of the oscillator 6.

Title: Accessing system of indexing order forming file using disk cash
Inventor: ISHIMARU KOUJI
IPC: G11B27/10
Filed: 1984-04-23
Abstract: PURPOSE:To increase the accessing efficiency of an indexing order forming file, by storing index sections in different locations at every external recording media when the indexing order forming file is created. CONSTITUTION:When a indexing order forming file is newly created to an external recording medium 2, index sections Ia'-In' of the medium 2 are respectively stored in different blocks, such as B0, B1,-Bk, Bk+1. When a host device accesses the index section Ia' to fetch the content of Da', for example, a block Da'1, the index section Ia' is stored in the sets S0 and S1 of the level L0 of a disk cash 3 by means of an external storage controller. When the external storage controller is accessed thereafter to fetch the Da'1, necessary data are read from a recording medium 2a and sent to the host device. When the index section Ib' is accessed, the index section Ib' is stored in the sets S2 and S3 of the level L0 of the disk cash 3 correspondingly to the blocks B2 and B3. Since no overlay storage of the index section to the disk case 3 is made, the accessing efficiency is improved.

Abstract: PURPOSE:To omit the use of the special hardware and to prevent the deterioration of throughput of a file access owing to the transfer of data carried out via another bus between hosts by adding a shared file to which the accesses are possible from both hosts onto an SCSI bus and attaining the access control. CONSTITUTION:It is checked whether a file control table had a change or not every time both hosts 12a and 12b carry out the processes in accordance with the request contents received from a user application. If the file control table had a change, this table is written into another file control table stored in a shared file storing device 15. then the change of the control table is given to another host by means of a command of a small computer system interface. Receiving this information, the host reads a file control table out of the device 15 and updates its own file control table. As a result, the file access control is attained between the hosts without using any special hardware.

Title: New crosslinking agent
Inventor: UENO AKIRA
IPC: C08K5/3415
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To obtain a vulcanizing agent having a crosslinking efficiency higher than that of N,N'-m-phenylenebismaleimide and excellent reversion resistance and a reversion inhibitor by using norbornane-bismethylmaleimide. SOLUTION: A norbornane-bismethylmaleimide represented by the formula is used. General-purpose diene rubbers which are required to have reversion resistance include particularly natural rubber and polyisoprene rubber. Its amount of use is 0.5-3phr when it is used in a sulfur/vulcanization accelerator vulcanization system. On the other hand, when it is used as a non-sulfur crosslinking agent (or vulcanizer) and a peroxide crosslinking co-crosslinking agent or a vulcanization retarder, it is used in an amount of about 0.5-5phr. The norbornane-bismethylmaleimide can be produced by subjecting norbornane diamine and maleic anhydride to a dehydrative reaction in the presence of a solvent. The improved crosslinking efficiency leads to the improvement in tensile strength, heat resistance and compression set resistance.

Abstract: PURPOSE:To prevent the abnormal signal output of the image in the end of the lifetime of a lamp for illuminating by impressing a load voltage higher than a lighting voltage at the time of selecting each processing mode to the lamp for illuminating before an image reading. CONSTITUTION:A lamp power source circuit 10 is composed so that the output voltage can be controlled by a data signal and a control signal from a main control circuit 5. The load voltage higher than the lighting voltage in each processing mode is impressed to the lamp for illuminating before the image reading at the time of selecting an image reading mode. Consequently, the lamp for illuminating in the end of the lifetime is destroyed by the load voltage, and the lifetime of the lamp for illuminating can be detected. Thus, the abnormal signal outputted of the image due to the unstable condition of the light quantity of the lamp for illuminating can be prevented.
