Title: Damping circuit and transmission system
Inventor: NISHINO TATSUO
IPC: H03H7/25
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To suppress production of ringing without causing a remarkable delay in signal response in a transmission line between input output buffer circuits whose output resistance differs between a signal leading state and a signal trailing state. SOLUTION: A damping circuit 106 consisting of a damping resistor 104 and a diode 103 connected in parallel with the damping resistor 104 is inserted to a transmission line 107. A sum of resistive components of a buffer output circuit 102 and the damping circuit 106 is made equal between a leading state and a trailing state as shown in following expressions; Rin+RD×RR/(RD +RR)≈RP+RR (in the case of RP<RN) and RP+RD×RR/(RD+RR)≈RN+RR (in the case of RP>RN), where RD is a resistance of the diode 103, RR is a resistance of the damping resistor 104, and output resistance of the buffer output circuit 102 is RP, RN in the case of RP≠RN.

Title: Method and apparatus for driving pile
Inventor: OGATA KOUJIROU
IPC: E02D7/18
Filed: 1979-12-13
Abstract: PURPOSE: To relieve load on the bearing of a vibrator as well as prevent the occurrence of noise by a method in which a great vibration is generated in the top of a pile by using a small exciting force by giving a right-angle-directional vibration to the axis of the pile so as to make the frequency the resonance frequency of the pile.  
     CONSTITUTION: A pile 1 is driven while giving a right angle-directional vibration in relation to the axis of the pile to the pile 1 by means of an vibrator 1, where the frequency of the vibrator 2 is regulated by means of an oil-pressure flow regulating valve 8 so as to make it coincide with the resonance frequency of the pile 1. Also, a frequency detector 9 is attached to the vibrator 2 and a frequency monitoring device 10 is also provided. Thus, driving work can be advanced while always monitoring the frequency of the vibrator 2, and also a great vibration can be generated in the top of the pile by even smaller exciting force. In addition, load imposed on the bearing of the vibrator 2 can be lessened.

Abstract: PURPOSE:To make it possible to effectively print in an emphasized fashion even when the emphasizing frequency of a letter or the like is high, or the degree of the emphasis on a letter or the like is varied, by changing the form and the printing color of the letter in accordance with the emphasizing informations different in the level of the emphasis. CONSTITUTION:Upon receipt of an emphasizing data from a host computer for emphasizing a letter, a control unit 1 outputs a form selection signal S1 for selecting the printing form of the letter corresponding to the emphasizing data and also a color selection signal S2 for selecting the printing color of the letter. A converting table 11 converts the printing mode in such manner, e.g., that when the inputted emphasizing data has four levels, level 0 represents a normal black letter, letter 1 a Gothic black letter, level 2 a normal red letter and level 3 a Gothic red letter, respectively. A data selector 3 selects the pattern data either for normal letter or for Gothic letter in response to the selection signal S1, from a font memory 2. A data distributor 4 distributes the pattern data selected by the data selector 3 either into a black pattern data or into a red pattern data, on the basis of the color selection signal S2. For example, one page of paper which has been printed in black first is overprinted in red.

Title: Recording sheet
Inventor: MATSUNAGA TERUO
IPC: B41M5/52
Filed: 1985-07-23
Abstract: PURPOSE:To obtain a recording sheet capable of giving a clear image, by incorporating an alkylimidazoline-type amphoteric surface active agent into a film comprising a mixture of a polyvinyl alcohol having a saponification degree of not less than 75% and polyvinyl pyrrolidone, in an amount of 0.1-5wt% based on the total amount of the resin. CONSTITUTION:The saponification degree of the polyvinyl alcohol must be not less than 75%, because a saponification degree of less than 75% results in poor compatibility with polyvinyl pyrrolidone. Polyvinyl pyrrolidone preferably has a molecular weight of 10,000-1,200,000. The mixing ratio of polyvinyl alcohol to polyvinyl pyrrolidone is suitably 90:10-10:90, from the viewpoint of dryability of the ink. The alkylimidazoline-type amphoteric surface active agent is used in an amount of 0.1-5wt%. If the amount of the agent is less than 0.1wt%, the effect of the agent is not displayed, whereas if the amount of more than 5wt%, the recording sheet becomes tacky, making it difficult to put the recording sheet to practical use.
