Abstract: PURPOSE:To inhibit the adhesion of a liquid acid onto the back surface of a steel plate, by sticking the back surface of the steel plate fast to the surface of an acid-resistant flexible sheet with magnetic power, and then supplying the liquid acid to the surface of the steel plate to acid pickle said surface. CONSTITUTION:An acid-resistant magnet sheet 1,e.g. prepd. by embedding many small permanent magnets in a rubber substrate while arranging their polarities, having the flexibility such that its surface is stuck fast to the back surface of a steel plate A when the steel plate A is mounted thereon is provided on a supporting stand 2. By mounting the steel plate A on said magnet sheet 1, the steel plate A is stuck fast to the surface of the magnet sheet 1. Thereafter, a brush 3 is moved along the arrow while supplying a liquid acid through a supply pipe 4 to the surface of the steel plate A, to perform the work of acid pickling. Thus, the acid pickling can be performed without the adhesion of the liquid acid onto the back surface of the steel plate A.

Title: Control method for local oscillation circuit of receiver
Inventor: TAKASUGI TOSHIYASU
IPC: H03L7/081
Filed: 1989-07-25
Abstract: PURPOSE:To prevent the fluctuation of an oscillating frequency due to temperature change by providing a temperature sensor and a memory, comparing the temperature at preceding and this operation for each intermittent operation, and stopping the intermittent operation of a phase locked loop at reception when a prescribed temperature change or over is recognized. CONSTITUTION:When a PLL is locked in intermittently and a voltage controlled oscillator VCO is subject to free run at a point of time of the synchronization is obtained, if a rapid temperature change exists, the oscillating frequency of the VCO not PLL-locked is fluctuated due to temperature. Then intermittent temperature detection is applied in a temperature detection comparison block, the temperature of preceding PLL lock-in and the temperature at present are compared. When there is a prescribed difference or over in the both, the PLL loop is not interrupted but the lock-in state is kept over a period to be received continuously. Thus, the fluctuation in the oscillating frequency due to a temperature change is suppressed.
