Title: Method for detecting small-size foreign matter in container
Inventor: SHINODA TAKAKAZU
IPC: G01N21/85
Filed: 1987-03-18
Abstract: PURPOSE:To easily detect small-size foreign matter with high accuracy, by blowing up the small-size foreign matter by a jet fluid to irradiate the same from the side surface with fanwise laser beam. CONSTITUTION:Small-size foreign matters 2 are blown upwardly from a container 1 by the air flow 4 from an air pipe 3. The laser beam 9a from a He-Ne laser 5 is expanded in its beam diameter by an expander 6 consisting of a convex lens 7a and a collimator 7b to become laser beam 9b which in turn becomes fanwise slit beam 9c through a columnar lens 8 to irradiate the vicinity of the upper end of the container 1. The beam 9c impinges against the small-size foreign matters 22, and reflected and scattering beams are incident to a camera 10 to be displayed on a monitor apparatus 14 and inputted to an image processing part 13 as an image signal and the presence, number and the size of the small-size foreign matters 2 are detected. By this method, the small-size foreign matters in the container 1 can be simply and easily detected with high accuracy.

Filed: 1978-05-31
Abstract: PURPOSE: To perform transposition of musical pieces having been program-inputted through simple key operation by obtaining the coded information after the transposition based on the coded information indicating the height of sounds and the coded information for transposition.  
     CONSTITUTION: Through operation of a key switch, the assigned address of an input control circuit VM is upped by the signal S 1  from a sequence control circuit SN and likewise the note codes of said address are converted to the codes after transposition in the case of height codes and are directly in the case of length codes inputted to buffer registers B 1 , B 2  respectively by the signal S 2 . Next, the sound source signal corresponding to the height code is outputted from a sound source signal VS by the signal S 3  and at the same time the sound source signal is applied to a speaker driver D by turning ON the time gate G 3  corresponding to the length code, thereby producing the desired sound from a speaker SP. When production of the sound corresponding to one note is finished, the signal from a counter content detecting circuit operates the sequence control circuit to convert desired notes to sounds until the end code is outputted, hence musical pieces are readily transposed.

Filed: 1986-03-25
Abstract: PURPOSE:To obtain a small-sized detector performing highly accurate measurement, by providing a spherical container sealed with a fluidized material having conductivity in the main body of a model and measuring the electric resistance value in said container to detect the angle of the model. CONSTITUTION:The small-sized container 33 provided in the main body 31 of a model is sealed with a conductive fluidized material so as to set the liquid level thereof to the center of said container 33. When the main body 31 is inclined to an angle theta, because the liquid level in the small-sized container 33 always crosses a gravity direction at a right angle, the part contacted with mercury 34 of a resistance lead wire 35 also changes by the angle theta. As a result, because the resistance value of the lead wire 35 also changes, said resistance value is measured by a resistance measuring device 36 to make it possible to calculate the inclined angle theta of the main body 31. By this method, the angle of the posture of the model main body can be detected while measurement is performed on a small scale within a short time.
