Title: Printer
Inventor: YAMADA HIROSHI
IPC: B41J9/50
Filed: 1985-05-02
Abstract: PURPOSE:To prevent a defective hammer printing pressure from being generated due to variations in ambient temperature and enable clear printing, by varying a hammer current in a steady state in accordance with leading end characteristics of the hammer current. CONSTITUTION:A hammer-driving means 101 performs such control that a hammer current for driving a hammer 100 becomes constant, by a constant current controlling means 102. The leading end characteristic of the hammer current is detected by a detecting means 103, and a detection output is supplied to a hammer current varying means 104. The means 104 varies the hammer current in the steady state in accordance with the leading end characteristic thus detected so that the energy supplied to the hammer 100 is maintained to be constantly fixed irrespective of variations in the ambient temperature. Accordingly, a defective hammer printing pressure is prevented from being generated due to temperature variations, and clear printing is performed.

Filed: 1989-04-14
Abstract: PURPOSE:To obtain a filter without deterioration in a signal by obtaining the maximum value of minimum values or the minimum value of maximum values between two adjacent signals among three adjacent video signals, operating and outputting them. CONSTITUTION:A signal which changes in the dimension of time is converted into pattern space, and filtering is executed by the deformation of the pattern. At first, a maximum value operator MAX is generated in OR and a minimum operator MIN in AND. A positive logical operation circuit A and a negative logical operation circuit B are generated by using OR, AND and a delay circuit DL. Next, a filter is constituted by the combination of the circuits A and B. Namely, the signals of an input terminal 1 pass through the positive logical operation circuit of the circuits 2-6, pass through the negative logical operation circuit of circuits 7-11 and is supplied to an addition circuit 20. On the other hand, they pass through the negative logical operation circuit of the circuits 2, 3, 12-14, pass the positive logical operation circuit of circuits 15-19 and they are inputted to the addition circuit 20. Thus, the negative and positive pulse patterns are controlled and the change of outputs due to the order of conversion is averaged.

Abstract: PURPOSE:To brake a falling specimen in the lower end space of a falling tower so as to securely stop it with out any strong shock by arranging elastic plate members, the through hole diameters of which in the center of the falling tower are gradually reduced at intervals of plural stages. CONSTITUTION:Many rubber made elastic disc plate members 3, 3', 3'' having circular through holes 4, 4', 4'' in their centers are arranged at intervals in the lower end space of a falling tower 1 formed underground and the diameter of any plate member is reduced as its position is lower. Elastic plate members 5, 5', 5'' having no holes are arranged in the same way below them and a fixed damper 6 such as a spring, etc., is provided on a bottom for emergency. Accordingly, the falling specimen (payload) 2 gradually receives a gradually growing frictional resistance successively from the elastic plate members 3, 3', and its falling energy is effectively absorbed to be stopped. In an emergency, it stops by the aid of the elastic plate members 5, 5'... and the fixed damper 6 and safety may be secured. Therefore, the falling energy of the experimental specimen is not drastically absorbed to be surely stopped.

Title: Light scatter type liquid crystal display element and driving method
Inventor: HIROSHIMA KOHKI
IPC: G09G3/36
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To obtain a display element which has high light transmissivity and a wide field angle by forming a light scatter system in the planar structure of a nematic liquid crystal cell by applying a proper voltage waveform and holding this state for a long time. SOLUTION: Chiral nematic liquid crystal is held between a couple of substrates which have electrodes an orientation films formed in order on the surfaces and also have the orientation films arranged opposite each other at an interval, and the chiral nematic liquid crystal has a structure which generates a twist angle in an initial state. In this case, the liquid crystal is transparent when applied with no voltage, and holds a light scatter state when applied with an intermittent pulse voltage and then varies in transmissivity thereafter corresponding to the applied voltage. Further, a light scatter state is generated by applying intermittent pulses of a high voltage in several cells in the transparent state where no voltage is applied and then intermittent pulses of a semi-high voltage are applied in several cycles to put the state back to the original transparent state.  Consequently, the liquid crystal element is obtained which need not use a polarizing plate.
