Title: Method for distilling ammonium chloride
Inventor: NAKAYA KEIICHI
IPC: C01C1/16
Filed: 1982-04-02
Abstract: PURPOSE:To increase the utilization rate of a Ca component, by feeding the Ca component to ammonium chloride in a preliminary mixing vessel and a finish mixing vessel in 2 steps. CONSTITUTION:NH4Cl and a Ca component such as milk of lime are fed to a preliminary mixing vessel 1 and mixed. The amount of the Ca component is less than the theoretical amount necessary for the reaction with NH4Cl. The mixture is sent to a cyclone 3 through a line 2 to remove sand, etc. contained in the Ca component from the system through a line 4, and the liq. is fed to a finish mixing vessel 6 through a line 5. Said Ca component is fed to the vessel 6 by an amount necessary for the reaction with the residual NH4Cl to prepare a liq. consisting of CaCl2 and an aqueous ammonia soln., and the liq. is sent to a cyclone 8 through a line 7. Solid matter separated from the cyclone 8 is returned to the vessel 1 through line 9, and the remaining liq. is sent to a distilling column 11, where NH3 and CaCl2 are separated from each other by distillation.

Title: Recording method for multichannel sound pcm signal
Inventor: TANAKA KUNIMARO
IPC: G11B27/029
Filed: 1980-04-22
Abstract: PURPOSE:To smooth punch-in operation by reproducing a sound by a reproducing multihead in front of a recording multihead and by performing switching to a new sound signal when a part given a punch-in command comes to the recording head. CONSTITUTION:When point P where punch-in operation is acutally performed reaches point P2, a sound is sent from terminal 13 of reproduction-side digital signal processing part 9. Then, the sound of point P is heard and then the recording button is pushed. Next, the input signal is delayed in digital circuit 10 until point P reaches P4 to set a recording state while digital circuit 15 is left connected to digital circuit 9, and a signal previously recorded on the tape is recorded to change-over switch 12 when point P reaches P4. This method forms section B wherein previously recorded information is rerecorded and similar section C before and after over-doubled section A and both the sections and section A are oross-faded, so that no abnormal sound will be generated. Thus, the punch-in operation is smoothed.

Title: Spring-utilizing water feeding apparatus for use with automatic hydraulic pumping machine
Inventor: NAKADA MITSUHATA
IPC: F04F7/02
Filed: 1981-04-11
Abstract: PURPOSE:To enable to lift water with no use of mechanical power such as an impeller or the like, by discharging water via a check valve through utilization of pressure rise produced by water dropped from a high place. CONSTITUTION:Water flowing vigorously into a water passage 2 from a high place impinges onto an inwardly opened water release valve 6 and forces it open, so that rapid pressure rise is caused in the water passage 2. This results in lifting of a check valve 3, so that water flows into a tank 4 while compressing air in the tank 4. Here, since the pressure in the water passage 2 becomes negative temporarily, a water release valve 6 is opened toward the inside of the passage 2 and water remaining therein is released to the outside. Subsequently, water is introduced again into the water passage 2 from the high place and the above-mentioned procedures are repeated. Thus, water introduced into the tank 4 is pumped up through a lifting pipe 4A and stored in a required station. In the above arrangement, a spring 9 is attached to the release valve 6, so that a desired valve opening timing can be selected by adjusting the tensile force of the spring 9 by a screw 7.

CONSTITUTION:When a disc body 12 consisting of a dielectric substance is placed between a high-frequency electrode 10 and a ground electrode 11, BCl3, gas is introduced at a flow rate of 50ml/min from a gas supply port 13, an output from a high-frequency power supply 15 is applied to the high-frequency electrode 10, and Al coated onto Si wafers 14 placed onto the electrode 10 is etched, an etching rate of Al does not depend upon the increase of the number of the samples and a loading effect can be suppressed in the same manner as a flow rate of BCl3 gas is increased and the velocity of flow is accelerated by narrowing a distance between the disc body 12 and the high-frequency electrode 10 up to 2cm or less. Accordingly, the ratio of the velocity of flow of the gas flowing on the surface of the sample to be etched to a diffusion rate in said plasma of molecules, atoms, ions, etc. existing in plasma must exceed 0.2 in general in order to prevent the reduction of the etching rate by the loading effect.
