Patent JP-H0268768-A (JP)
Title: Fm signal processing circuit
Inventor: SHIBUE SHIGENORI
IPC: G11B20/06
Filed: 1988-09-01
Abstract: PURPOSE:To improve an S/N by relatively emphasizing a lower side wave level to an upper side wave level as the lower side wave level is small in the lower side wave range of an input FM signal. CONSTITUTION:The lower side wave components of the input FM signal fetched by a low-pass filter 11 are supplied to a limiter 16, and only a low level signal is passed by the amplitude limitation at the limiter 16. For such a reason, by an adder 18, an output signal added to the delay-compensated input FM signal is made into a signal in which the level is emphasized as the lower side wave level is small, and a modulation degree is increased. Thus, in the low level signal in which the deterioration of the S/N is likely to be generated, without inducing a waveform distortion such as an inversion phenomenon, the S/N after a demodulation can be improved.

Inventor: ARII KUMIO
IPC: F26B3/30
Filed: 1990-08-23
Abstract: PURPOSE:To perform a sufficient drying of a pine tree material and facilitate a prevention of ejection of resin by a method wherein a far infra-red ray is radiated against the pine tree material and an inner temperature of the pine tree material is kept within a specified range of temperature for a specified period of time in response to a plate thickness of the wood material to be radiated. CONSTITUTION:As a pine tree material 1 is fed into a processing furnace 10, the material 1. is moved by a conveyor 12 at a specified speed. This material 1 is radiated with an infrared ray from upper heater devices 50a, 51a, 52a, 53a and lower heater devices 50b, 51b, 52b and 53b, respectively. At this time, after an inner temperature of the pine material is held at 100 to 150 deg.C for a specified period of time, then the radiation of a far infra-red ray is stopped and then the pine material processed with the far infrared ray is passed through hot air (for example, a hot air furnace utilizing discharged gas from the processing furnace) of about 60 deg.C for several minutes. In this way, various organic chemical substances including rosin of the pine tree material start to soften at about 50 to 55 deg.C together with moisture and flows along a pine material cell wall or a resin path. However, if this material is kept at a temperature of about 100 to 150 deg.C for a specified period of time, they are changed into a crystalline state and hardened.

This creep is the same as a conventional torque converter type automatic transmission, however the opening of the valve 6 is controlled by the pushing-down quantity of a brake, and the car speed is controlled by the pushing-down quantity of the brake pedal undependent on the load of a sloping road or cargo. And since a distance between cars sensor 9 is provided in the captioned device, an alarm is given with an alarm display device 10 when a vehicle closes within the distance between cars set according to the car speed.
