Title: Production of sodium dicyanamide
Inventor: ABE KOICHI
IPC: C01C3/16
Filed: 1987-04-14
Abstract: PURPOSE:To produce easily sodium dicyanamide having high purity in high yield by allowing cyanogen chloride to react with ammonia, extracting ammonium dicyanamide in the reaction product with acetone, and allowing the extracted ammonium dicyanamide to react with NaOH. CONSTITUTION:Cyanogen chloride is dissolved in a solvent such as benzene, and the reaction expressed by formula I is caused by blowing ammonia into the soln. Then, a mixture of crude crystals of obtd. ammonium dicyanamide and ammonium chloride are washed with acetone, thus ammonium dicyanamide alone in the mixture of the crude crystals is dissolved. Aq. NaOH is then added to the obtd. washing liquid, and the reaction expressed by formula II is caused by heating the liquid under reduced pressure, evaporating simultaneously the acetone, after, and ammonia. Thus, aimed sodium dicyanamide is obtd. as residue after evaporation. The obtd. sodium dicyanamide is used for a raw material for chlorohexidine which is one of the nontoxic disinfectants.

Title: Multi-frequency signal receiver
Inventor: ITOU AKIRA
IPC: H04L27/26
Filed: 1981-06-12
Abstract: PURPOSE:To exactly prevent a malfunction by a spurious signal, by utilizing the fact that a lot of frequency components except a PB signal are contained in the spurious signal. CONSTITUTION:By a band-elimination filter 13A of a spurious signal detecting circuit 13, a band of a multi-frequency signal component from a spurious signal is suppressed and removed, and it is detected by a level detector 13B. When a level of this spurious signal exceeds a threshold level, a pulse train output is obtained from the detecting circuit 13B. When the spurious signal is inputted continuously exceeding a prescribed time, an output of a rectifying circuit 13 is obtained, an input signal duration time monitoring timer of a time limiting circuit 12D is forcibly released, therefore, an output timer is not started and a gate signal is not applied to output gate circuits 12E, 12F. Accordingly, even if an original detecting circuit of a multi-frequency signal receiver has detected the spurious signal as a multi-frequency signal by mistake, the output concerned is not sent out from output terminals OUT1-8, and a malfunction is prevented.

Title: Game machine
Inventor: SATO FUMIAKI
IPC: A63F7/02
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To improve interest by informing that a special pattern will be stopped and displayed before this pattern is stopped in case when a stopping pattern is the special pattern. SOLUTION: It is judged whether a playing ball passes through a central gate 7. When it passes through, it is judged whether the stored value of a judging memory expressing that deviation of pattern of pattern displaying parts L1-L3 is possible is a specified value, e.g. 9. If it is not the specified value, the judge result of the judge memory is stored and it is returned to a main program. When it is the specified value and the value of a judge counter is not the specified value, it is judged whether it is low probability condition or high probability condition. Under high probability condition, as a special playing condition, a specified number, e.g. 3 is stored in the judge memory. In the case when the specified number 3 for generating this special playing condition is stored, a pattern for reach condition is displayed.  A player can recognize thereby a different condition from an ordinary condition and the interest is improved.

Abstract: PURPOSE:To drive a body securely and reciprocally while preventing a wire rod such as a wire from falling off a pulley by flanging a driving body of rotation in a specific shape in the device which drives the body reciprocally through the wire rod and body of rotation. CONSTITUTION:The wire 3 is wound around the wire pulley (dirving body of rotation) 11 of a reversible motor 7 and fixed to both end parts 4' and 4'' of the original platen 4 of a copying machine so as to drive the original platen 4.

Further, a flange 10 is fitted to one end of the pulley 11 so that the upward tilt angle beta of the flange 10 is 3- 5 deg.C and its bevel length l is >=2 times as large as the diameter (d) of the wire. Then, even when the wire moves up the bevel, tensile force F is generated toward the center axis of the pulley and a component F' parallel to the bevel operates, so that the wire 3 is returned to the pulley 11. Therefore, the wire never falls off the pulley and the original platen, etc., are driven securely and reciprocally.

Title: Detecting device for abnormal condition in temperature for air conditioner
Inventor: TSUTSUI KAZUO
IPC: F24F11/02
Filed: 1980-07-04
Abstract: PURPOSE: To advance the start of detection of abnormal conditions by the device for detecting abnormal conditions in room temperature for the air conditioner installed in a building by a method wherein a transient range from a starting to a target temperature reaching is determined by a change rate of detected values of temperature.  
     CONSTITUTION: The transient range is divided into a primary adjustment range in which the temperature is brought compulsively to a preset value 13 and a secondary adjustment range in which the temperature is brought as near the preset value 13 as possible by a proportional control function. The device for detecting abnormal conditions in temperature starts operating at t 01  at which the temperature is determined to have transferred to the secondary adjustment range. This determination is obtained by differentiating a change in the measured value of temperature in a secondary adjustment transfer point detecting circuit. With such a construction, the detector can be operated early enough within a stable range and the width 14 between the upper and lower limits of alarm point can be reduced.
