Abstract: PURPOSE: To make multistage shift possible and store a shift position independently of power source turning-on and off to cancel troublesome operations, by providing one key to utilize combination of this key and provided keys.  
     CONSTITUTION: This apparatus is constituted by providing one shift position selection key SFT on the keyboard of key input part KBR. Shift code flags F 3  and F 4  are a latch to determine the system consisting of D-type FFs and read out respective outputs of external memories F 1  and F 2  with clock pulses. Outputs C 11  and C 12  of flags F 3  and F 4  become the whole of the input of control part CRT, and the system determined by states of outputs C 11  and C 12  is selected. If the shift instruction is SFT.X, C 11  and C 12  become 10 to select the German system; and if the shift instruction is SFT.C, the French system is selected. Since the shift code is stored by external memories F 1  and F 2  even when the main power source is turned off, shift position selection signals CX1 and CX2 and signal LD are outputted according to the shift code to set a code by set signal LD from a CRT when a key for system designation is operated.

Title: Muting controller of magnetic reproducing device
Inventor: TAKAHASHI MASANORI
IPC: G11B15/10
Filed: 1982-02-26
Abstract: PURPOSE:To release a muting circuit only when a head base moves to a play position PLAY, by detecting the position PLAY of a head through a sensor, and allowing a control part to perform control by its detection signal, and thus executing muting release in a short time. CONSTITUTION:While a magnetic reproducing device is in a stop state, the head base is at a stop position STOP, so the output of the sensor 25 is ''L'', and a microcomputer, therefore, outputs no muting resetting signal. With a play switch 2, the microcomputer 21 controls a head base driving device 23 to move the head to the position PLAY, so a signal at a level ''H'' is inputted from the sensor 21 to the microcomputer 21. Therefore, the muting resetting signal is outputted from the microcomputer 21 to a muting circuit 24 to release the circuit 24.

Title: High intensity burner
Inventor: KOMAI YUKIROU
IPC: F23D14/02
Filed: 1984-02-21
Abstract: PURPOSE:To perform high intensity combustion and at the same time contrive to decrease NOx by a structure wherein a porous body and a combustion gas controlling ports are provided at a combustion chamber. CONSTITUTION:A part of combustion air enters a mixing chamber 2 and jets together with fuel out of a flame port 1. The remaining part of the air passes through the interior of air outer chamber 4 as secondary air and jets out of air holes provided on an air plate 7 in order to perform high intensity combustion together with mixture. A part of combustion gas reaches a heat exchanger 6 through passages provided on a porous body 12. The remaining part of the gas flows backwards along the wall of the combustion chamber 5 and reaches the heat exchanger 6 through gas controlling ports 14. In addition, if the flame length becomes longer, the combustion is accelerated by means of the porous body 12. Due to the structure as mentioned above, the downstream part in flame zone is contaminated with the combustion gas passing through the combustion gas controlling ports 14, the flame temperature is lowered, resulting in decreasing NOx value by half.
