Title: Speaker and speaker device
Inventor: FUJIHIRA MASAO
IPC: H04R9/02
Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To enhance the sound radiation of a small speaker through the use of a single speaker, to expand low band sound pressure and the radiation of the low band and also to prevent a light weight speaker box from being vibrated by constituting a speaker device so that the reaction force of the sound radiation force of a diaphragm is supported by means of air which passes through a duct. SOLUTION: An acoustic signal is supplied to an input terminal 29. Then a diaphragm 7 is driven in a direction indicated by an arrow F1, and the reaction force -F1 is applied to the diaphragm 7 by the sound radiation force of F1. In the meantime, a high sound diffusing body 24 is fixed on a center pole 3a so that a duct radiation force F2 in the opposite direction of the force F1 of the diaphragm 7 is applied by inertia to stop the board 7. The opposite direction action force F2 is regarded as the action force which is excited by the reaction force -F1 of the action force F1 of the diaphragm 7. Therefore, the reaction force -F1 with respect to the sound reflection force F1 of the diaphragm 7 and the reaction force -F2 with respect to the action force F2 acting on the duct of the high sound diffusing body 24 are mutually cancelled or attenuated.

Title: Laser device
Inventor: KARUBE NORIO
IPC: H01S3/05
Filed: 1983-09-13
Abstract: PURPOSE:To extend the life of a laser by internally containing a laser active substance which gradually reduces in a small signal gain during operation in a laser resonator, and decreasing the output coupling rate of the resonator as compared with the optimum output coupling rate corresponding to the initial small signal gain, thereby performing the increase in the minimum guaranteed output. CONSTITUTION:A laser active substance with gradually decreases in the small signal gain is internally contained in a laser resonator which is composed of a laser tube 1, an output coupling mirror 3 and a fully reflecting mirror 3 during operation, and the output coupling rate of the resonator is decreased as compared with the optimum output coupling rate corresponding to the initial small signal gain. For example, in case of the external mirror type of a sealed tube CO2 laser unit, a partial reflecting mirror 4 and a high reflecting film 4' are formed on the surfaces of the mirrors 3, 3'. The output coupling rate is adjusted by controlling the reflectivity of the film 4.

Title: Image reader
Inventor: FUTATSUKA MASAHIKO
IPC: H04N1/04
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To eliminate a shadow generated by a level difference provided in an original at the time of reading images by combining a light source and a reflector and irradiating a read point. SOLUTION: A light source lamp 3 irradiates the read point 6 of a white reference 5 from the rear part of the carrying direction of the original 1 as light source light and light reflected by the reflector 2 irradiates the read point 6 from the front part of the carrying direction of the original as virtual light source light. The original 1 is irradiated with the light source light by the light source lamp 3 and the virtual light source light reflected by the reflector 2 at the time of passing through the read point 6. Even though time front end of the original 1 generates a shadow by the light source light at the time of advancing to the read point 6, the shadow is eliminated by the virtual light source light by the reflector 2 simultaneously. Further, when the rear end of the original 1 is passed through the read point 6, since the rear end of the original 1 is irradiated with the light source light, the shadow is not generated. Thus, the shadow of the original 1 is not contained in the image data.
