Title: Howling preventing equipment
Inventor: YAOITA AKIRA
IPC: H04R3/02
Filed: 1986-11-27
Abstract: PURPOSE:To block the generation of howling by inserting a phase fluctuation circuit and a variable gain amplifier circuit controlled by an output of a control signal generating circuit in a system forming an acoustic loop. CONSTITUTION:A microphone 1 collecting mainly the voice of the sound source aud a microphone 7 collecting mainly speaker sound are used in an acoustic equipment having sound collection and reproducing system and the quantity of the signal level inputted to both is compared to control the variable gain amplifier circuit. Thus, the stable variable gain control is attained independently of the quantity of sound volume level in the sound field. Moreover, the phase fluctuation circuit 5 is provided to give a slow fluctuation to the phase of the sound wave radiated from the speaker thereby preventing the resonance of the sound wave only having a specific wavelength in the sound field, then no howling is caused and the output of the maximum sound volume level outputted by the accoustic equipment is obtained in the range where the feedback loop gain does not exceed the unity.

Title: Method for correcting variation in focus position of plastic lens system with temperature
Inventor: ONO NOBUAKI
IPC: G02B7/02
Filed: 1988-11-07
Abstract: PURPOSE:To easily correct variation in focal length with temperature by simple constitution by composing a lens system of four elements in two groups and setting properly the coefficients of linear expansion of positioning members for the front and rear groups. CONSTITUTION:The front group of a positive lens L1, a negative lens L2, and a positive lens L3 is positioned by a front-group positioning member and the rear group of a negative meniscus single lens L4 is positioned by a rear-group positioning member 2. Then the coefficient of linear expansion of the rear-group positioning member is set small and that of the front-group positioning member is set large. Therefore, the positioning members 1 and 2 deform thermally with temperature, but the front group and rear group differ in displacement quantity owing to the difference in coefficient of linear expansion and the gap between the front and rear groups varies with the temperature. This is utilized to set the coefficients of linear expansion properly to correct the variation in the focal length of the plastic lens with the temperature.

Title: Float type laser level gage
Inventor: FUJIWARA AKIKAZU
IPC: G01F23/64
Filed: 1987-11-07
Abstract: PURPOSE:To prevent irregular reflection due to the disturbance of a liquid level and to make it possible to measure the liquid level highly accurately, by providing a float in a guide sleeve, whose one part is immersed in liquid metal, reflecting laser light from the float, and receiving the light. CONSTITUTION:A float 1 is provided in a guide sleeve 2. The reflecting surface of the top of the float has a spherical shape. Even if the float is inclined, the shape of the exposed part from a liquid level 4 is not changed. Therefore, the reflected light of projected laser light 13 is always reflected toward a laser light emitting and receiving device 7. Since the inner diameter of the sleeve 2 is almost equal to the outer diameter of the float 1, evaporation of high temperature liquid metal can be reduced. Gas is sent from a pipe 11 with pressure and exhausted through a gas exhausting hole 5 out of the sleeve 2. Thus ascending of vapor is prevented, and clouding of the emitting and receiving device 7 can be prevented. In this way, the light 13 is projected on the float 1 from the emitting and receiving device 7, and the reflected light having sufficient amount can be received 7. The received signal is inputted into a converter 9. The level of the liquid 4 can be indicated on a display 10 in consideration of the height of the float 1 from the liquid level 4.
