Title: Digital recording and reproducing device for image signal
Inventor: ISOMURA MASAICHI
IPC: H04N5/92
Filed: 1986-03-06
Abstract: PURPOSE:To obtain the sampling value of a continuous image signal from the sampling value of an effective picture period read from a recording means and the sampling value of the blanking period made into zero by converting the sampling value of the effective picture period to a relative deviation to the optional sampling value of the blanking period and writing it to a digital memory. CONSTITUTION:A latch circuit 17 latches the sampling value (the second sampling value) of a suitable timing during the blanking period of the sampled image signal, holds the sampling value during one horizontal scanning period until the sampling value (the first sampling value) of the next blanking period is latched, obtains the deviation of respective sampling values (the first sampling value) of the effective picture period during one horizontal scanning period with a subtracter 18, and converts the sampling value of the effective picture period so that the sampling value of the blanking period can be zero. At the time of reproduction, for the sampling value (the first sampling value) read from a digital memory 5, the blanking period is omitted, and when the sampling value of the blanking period is made into zero, the sampling value of the continuous image signal can be obtained.

Title: Polymer and its production
Inventor: NAGATOMO AKINORI
IPC: C08L101/16
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To obtain a polymer which exhibits an excellent toughness in its use and does not generate a toxic substnance in its decomposition process after disposed of by selecting a polymer having specific carbonate monomer units in the molecule. SOLUTION: A polymer is selected which has carbonate monomer units represented by formula I in the molecule. The polymer is produced by reacting 3,6-bis[(4-hydroxyphenyl)methyl]-2,5-diketopiperazine represented by formula II with phosgene. Since 3,6-bis[(4-hydroxyphenyl)methyl]-2,5-diketopiperazine is a cyclic dimer of tyrosine (i.e., an amino acid), a carbonate polymer produced therefrom generates tyrosine only at the decomposition product derived from raw materials in the decomposition process of the polymer. Thus a high safety can be expected.

Filed: 1981-04-02
Abstract: PURPOSE:To display in unit a numeric data including decimal point, by enabling to input through a key in combination of keys ''thousand'', ''10 thousand'' or ''100 million'' and a decimal point key. CONSTITUTION:In inputting ''30,000.4'', for example, when ''3'' key is operated from a key input section 11, an operation signal is given to an ROM address section 12. An ROM13 outputs a code signal to the entry ''3'' to the 0-digit of an X register via a bus line c. When the ''10 thousand'' key 11d of the section 11 is operated, the operation signal is given to an ROM address section 12. Thus, an ROM13 outputs a code signal ''4'' to the ''ten thousand'' key 11d is outputted to a shift register 20. The result is discriminated at a decoder in a state discriminating section 21 and the microprogram for the process when ''10 thousand'' key is operated after the entry key operation is executed. When a decimal point key is operated, a microprogram processing the operation of the decimal point key is operated after the ''10 thousand'' key operation.

Title: Feedforward controller
Inventor: KOJIMA FUMIO
IPC: G05B11/32
Filed: 1985-03-13
Abstract: PURPOSE:To stabilize and adjust quickly a control system by detecting the generation and the direction of the disturbance and preventing a case where a feedforward compensating element works in the direction opposite to the disturbance based on the disturbance direction discriminating signal. CONSTITUTION:A disturbance detecting part 42 is connected to the output side of a feedforward compensating element 41 serving as a delay/advance element which compensates the disturbance produced by the variation of the material feed amount, etc. The part 42 decides the generation of the disturbance when the output of the compensating element changes more than a prescribed level within a prescribed period of time. At the same time, the part 42 discriminates the increase and decrease directions and delivers a disturbance detecting signal S1 and a disturbance direction detecting signal S2. This signal S1 is held by an action signal generating part 43 for a prescribed period of time. Meanwhile an ON action signal is supplied to a limiter 44 on the following stage to inhibit a case where the feedforward signal works in the direction opposite to the signal S2 against the output of the element 41. Thus it is possible to prevent the disturbance of a feedback control system and to stabilize it.
