Abstract: PURPOSE:To efficiently control the capacity of the air conditioner by a method wherein the set value of the blow-off temperature is set higher than the blow-off temperature, at which the direction of blown-off air is changed and said set value is compared with detected temperatures. CONSTITUTION:The room temperature is detected by a thermistor 1 in terms of resistances and sent to a central processing unit (CPU) 5 by being converted into digital data by an A/D converter 2. On the other hand, the blow-off temperature is detected by a thermistor 3 in terms of resistances and sent to CPU5 by being converted into digital data by an A/D converter 4. CPU5 rotates a stepping motor 11 so that the air blows-off horizontally when the blow-off temperature detected by the thermistor 3 is below the set value of the blow-off temperature and blows-off downward when said temperature is above said set value. When the blow-off temperature lies between 40 deg.C and 52 deg.C and yet the frequency, on which the compressor is driven, is different from the frequency, which is decided on the room temperature, the former frequency is set to be brought near to the latter frequency by 15Hz. On the other hand, when the blow-off temperature is higher than 52 deg.C, the frequency, on which the compressor is driven, is set to be lowered by 15Hz, while when lower than 40 deg.C, the frequency is set to be raised by 15Hz. In addition, the air blows-off horizontally when the blow-off temperature is 37 deg.C or lower, while downward when higher than 37 deg.C.

Title: Speaker
Inventor: SHIMOKOORIYAMA MAKOTO
IPC: H04R7/02
Filed: 1982-09-21
Abstract: PURPOSE:To form a small-sized, lightweight speaker excellent in regenerative frequency characteristic and high in followability and efficiency to input signals, by using a high magnetic permeable material on which a magnetizing pattern is recorded, as a diaphragm. CONSTITUTION:When a signal voltage is applied from an input terminal 44, force from above or below shown by the arrow 45 in the figure is applied to a projected part 32 by interaction of magnetic lines of force with a signal current, i.e. Fleming's left-hand rule, because magnetic lines of force 42 from the magnetizing pattern of the projected part 32 intersects the direction of disposition of a returning wire 33 at right angles. At this time, as the returning wire 33 returns of every magnetizing pattern and the direction of current changes, an upward or downward force is applied to the projected part 32 as a whole. Thus, sound waves corresponding the input signals can be generated by the diaphragm. By this way, a lightweight diaphragm having a large area high in rigidity can be formed by using a material high in magnetic permeability.

Title: Light scanner
Inventor: SHIRASAKI TAKAYUKI
IPC: H02K7/065
Filed: 1978-12-23
Abstract: PURPOSE: To achieve the improvement in the accuracy of the light scanner by constituting the torsion spring bar of a vibrator by a constant elasticity alloy of small change in resonance frequency occuring in temperature change thereby reducing the amplitude fluctuations of the vibrator occuring in temperature change.  
     CONSTITUTION: When sine wave current is flowed to the stator driving coil 10 of a moving-iron type reversible motor, a difference in magnetic power occurs between magnetic pole surfaces 9a and 4a and between 9b and 4b and an armature 4 causes a change in angle nearly proportional to current. Hence, the vibrator constituted by the armature 4, speed detector and mirror 3 starts self-resonating vibration at its natural frequency. The mirror 3 fixed to the torsion spring bar 2 rotates and vibrates laterally at a fixed amplitude from the static position, causing the beam incident from the incident window 22b of a junction barrel 22 to scan through a reflecting window 22c. Thereupon, if the torsion spring bar 2 is constituted by the constant elasticity alloy of a small change in resonance frequency owing to temperature change, the amplitude fluctuations of the vibrator become smaller to a negligible level, thus the accuracy of the light scanner may be increased.
