Title: Frequency discriminator circuit
Inventor: OOHARA NAOYUKI
IPC: G01R23/15
Filed: 1978-09-30
Abstract: PURPOSE: To accurately discriminate a frequency with a simple construction of a frequency discriminator circuit by triggering a retriggerable monostable multivibrator by the output pulse of a zero level detector circuit for detecting the zero level of an AC signal.  
     CONSTITUTION: The output voltage of a dtansformer 2 for lowering the voltage of an AC power supply 1 is rectified in full wave by a full-wave rectifier 3, and the rectified voltage is applied to a zero level detector circuit 4. The detector circuit 4 detects the zero level of the output of the rectifier 3 to thereby trigger a retriggerable monostable multivibrator 5. The multivibrator 5 is triggered by the output pulse of the circuit 4 to thereby generate a pulse having a duration corresponding to the zero level detection pulse of the standard frequency voltage in its pulse duration. This output pulse is applied to a flip-flop 6 to thus discriminate the frequency.

Title: Cement composition
Inventor: YOSHIDA HIDEJI
IPC: C04B7/32
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To shorten the curing time and, accordingly, the production time of a cement chip board or cemented excelsior board by using a powdery cement composition having high fineness and containing SO3 , 3CaO.Al2 O3 and 3CaO.SiO2 at specified ratios. SOLUTION: This cement composition contains 3.5-15 pts.wt. of SO3 , 8-20 pts.wt. of 3CaO.Al2 O3 (abbreviated to C3 A) and 40-70 pts.wt. of 3CaO.SiO2 (abbreviated to C3 S) and has a fineness of 4,300-8,000 cm<2> /g. Since the cement composition has high finesse, the hydration reaction proceeds at a high rate to quickly increase the strength of cement. The sulfate ion in a liquid phase is increased by the high SO3 content to promote the generation of etringite and increase the initial strength of cement. High C3 A content of the composition results in the formation of a large amount of hydrated calcium aluminate at the initial stage of the hydration of cement to prevent the inhibition of hydration caused by an organic retarding substance.

Filed: 1992-04-17
Abstract: PURPOSE:To improve convenience for users and to prevent malfunction by changing an initially set item from a main menu picture to a sub menu picture when any initial item not set yet is set. CONSTITUTION:When the menu key of an operation part 9 or a remote commander RC is inputted, a control part 6 judges a numerical value set at a flag M and when '1' is set, a main menu containing the initially set item in various set items is displayed. Then, the initially set item is selected in the main menu and when it is executed, '0' is set to the flag M. when the next menu key is inputted, the picture is displayed after moving to the sub menu which does not contain the initially set item. Since the initially set item not to be almost used after being temporarily set is moved to the other picture not to be normally used after setting, convenience for users is improved and malfunction can be prevented.
