Title: Production of nickel hydroxide
Inventor: HONDA MASAHARU
IPC: H01M4/52
Filed: 1990-02-27
Abstract: PURPOSE:To improve the controllability of particle size distribution by intermittently increasing the amount of an aqueous solution of an alkali metal hydroxide over a prescribed period to control the pH of the reaction system, thereby forming fine particles of Ni(OH)2 acting as nuclei. CONSTITUTION:An aqueous solution of an Ni salt having a concentration of 0.5-3.5mol/l or an aqueous solution produced by adding 0.01-5mol/l of a Co salt and 0.01-5mol/l of a Cd salt to the above solution is continuously supplied to a reactor 1 through a feed line 3. The reactor is further supplied with 1.21-10mol/l aqueous solution of an alkali metal hydroxide through a feed line 7 and 3-7.5mol/l of an ammonium ion source through a feed line 5. The mixed solution is made to react by maintaining the temperature to 20-80 deg.C and pH to 9-12. After the reaction, the pH of the system is quickly raised by intermittently increasing the feeding rate of the aqueous solution of alkali metal hydroxide and is maintained in the state for a prescribed period to form fine particles of Ni(OH)2. Thereafter the feeding amount of the aqueous solution of alkali metal hydroxide is returned to the normal level to proceed the reaction. The formed fine particles of Ni(OH)2 are delivered through a delivery line 15.

Abstract: PURPOSE: To constitute an intermediate frequency amplifier of low current consumption by connecting collector-emitter circuits of first and second amplification transistors Trs, constituting the intermediate frequency amplifier between two high and low power lines in series. CONSTITUTION: The output signal of an intermediate frequency amplifier is obtained in a signal output B from the collector of a Tr Q2. The secondary side of a transformer T2 has a first grounded terminal and a second terminal, where an output voltage Vs of the intermediate frequency amplifier is grounded. Consequently, the signal is sent to the output B from an input Ve through the base and the collector of a Tr Q1, a transformer T1, and the Tr Q2. The signal amplified by the Tr Q1 is connected to the Tr Q2 through the secondary side of the transformer T1. Since the emitter and the base of the Tr Q2 are grounded, the secondary voltage of the transformer T1 is given between the emitter and the base of the Tr Q2. This voltage is amplified by the Tr Q2.

IPC: G11B7/085
Filed: 1982-03-26
Abstract: PURPOSE:To retrieve a desired track stably at a high speed, by preventing a tracking element from vibration even when a linear motor is moved at a high speed during coarse retrieval. CONSTITUTION:The linear motor 69 moves a conveyance table 71 toward a desired track according to the signal of a signal generating circuit 75. The vibration of the tracking element 56 is caused by inertia when the conveyance table 71 varies in speed with time. For this purpose, said variation is detected by a speed variation detecting circuit 73, whose signal is applied to the tracking element 56 through a synthesizing circuit 66 and a driving circuit 67 to cancel the force applied to the tracking element 56. Thus, the vibration of the tracking element 56 is reduced.

Abstract: PURPOSE:To improve the channel selection to a reception signal by providing a 1st PLL circuit and a 2nd PLL circuit and setting the frequency division ratio of a 1st pre-stage frequency divider larger than the frequency division ratio of a 2nd pre-stage frequency divider. CONSTITUTION:Frequency division ratios N, M of 1st and 2nd pre-stage frequency dividers 12, 16 included respectively in 1st and 2nd PLL circuits 31, 32 are selected so as to be M>M. When the 2nd PLL circuit 32 is interrupted due to an external cause at the switching of a reception frequency and activated again, the circuit 32 is operated to lock the phase of an output signal of a variable frequency divider 17 with respect to a reference frequency signal from a reference frequency generating circuit 21. As a result, the oscillated frequency of the 2nd local oscillator 7 is set accurately to a value corresponding to the control signal from an input terminal TC 2 to prevent misoperation of channel selection. Moreover, the frequency division ratio of the frequency divider 12 provided on the circuit 31 is selected in a way of selecting harmonic wave disturbing the reception signal to a comparatively high order among the harmonic waves of the output signal and the effect on the reception signal is reduced.
