Title: Controller of tape recorder
Inventor: SATOU SUSUMU
IPC: G11B15/03
Filed: 1979-07-16
Abstract: PURPOSE:To exercise control over the operation of a tape recorder securely in a short time by a high-speed run by using as an auxiliary control is signal for tape run speed deceleration a coincidence output right before the counter value of the tape recorder reaches a fixed value. CONSTITUTION:With program searching of a tape positioned, counter CT is reset to zero and memory M2 is stored with a fixed value. After reproduction up to a random position, rewinding the tape at a high speed makes counter CT count down clocks and immediately before its count value reaches zero, comparator CP2 generates a coincidence output in terms of the memory value of memory M2. This output passes through AND gate AND1, left open with a rewind signal, to obtain an auxiliary signal for tape run deceleration. Therefore, the tape stops at a fixed position with accuracy after deceleration. Further, switching at a desired tape position in operation mode from high-speed run operation is similarly performed securely in a short time without wasting time.

Title: Oxygen density detecting apparatus for burner
Inventor: YAMAGUCHI HIROSHI
IPC: F23N5/00
Filed: 1980-07-01
Abstract: PURPOSE:To make it possible to derect the existence or nonexistence of a flame and the density of oxygen in the burner by a metod wherein the rate of increase of an ion current after the initiation of combustion of the burner is varied between a predetermined period of time and after a lapse of the predetermined time in the captioned apparatus using ion current detecting means. CONSTITUTION:When a heater or the like is ignited, a flame is formed on a burner head 2 and at the same time, a timer 5 released from a reset signal E is operated. Consequently, an ion current flows through the burner head 2 via a flame rod 1 due to the flame and then joins a high level DC signal from the timer 5 to be converted into a high level voltage signal A through a resistor 8. The voltage signal A is impressed upon a voltage comparator 13 after it is converted into a voltage signal B through a protective resistor 10. In this case, the signal A is made to become associated with the density of oxygen in the heater when the timer 5 generates a low level DC signal F after a lapse of a predetermined time, that is, after a lapse of time in which the ion current is stabilized, while when the voltage signal B decreases lower than a reference voltage, a signal D is interrupted to thereby alarm that the heater is short of oxygen.

Abstract: PURPOSE:To allow the quick course change, course parallel shift, and stop and improve steerability by protruding a pair of right and left rudders symmetrically across a hull center line on the bow bottom in a ship provided with a propeller and a rudder at the stern. CONSTITUTION:When a ship 1 is to be shifted to the left in parallel on its course, a stern rudder 03 is rotated counter-clockwise, and bow rudders 6p, 6s are also rotated counter-clockwise.

Next, when the ship 1 is to be quickly stopped, bow rudders 6p, 6s are rotated counter-clockwise and clockwise respectively by about 90 deg. so that rudder faces are made vertical to the bow stream 7, then the ship 1 is quickly stopped. Furthermore, bow rudders 6p, 6s can perform a turning action likewise as the stern rudder 03 to improve the turning capability. In addition, when bow rudders 6p, 6s are kept in parallel with the hull center line respectively, they serve as the turning resistance against disturbance, thus the course maintaining performance can be improved.
