Title: Liquid density measuring instrument utilizing magnetic floatation of superconductor
Inventor: FUJII KENICHI
IPC: G01N9/10
Filed: 1987-09-09
Abstract: PURPOSE:To simplify a magnetic densimeter by providing a buoy where a superconductor to be put in sample liquid is enclosed and a magnetic flux generation body which floats said buoy by the Meisner effect of the superconductor. CONSTITUTION:When a proper DC current is supplied to a coil 3 while the buoy 8 is dipped in the sample liquid 7, a magnetic field is produced in the axial direction of the coil 3 and the buoy 8 in the sample liquid 7 floats stably and becomes stationary by the Meisner effect of the superconductor. When this buoy 8 floats, its reaction is applied to the coil 3, so weight on an electronic scale 1 increases by force corresponding to the reaction. In this case, the density rhoof the sample liquid 7 is expressed by rho={m-(M2-M1)}/V (M1 and M2: reads on the scale before and after the buoy floats). Therefore, the difference between said reads is measured to measure the density of the sample liquid 7.

Abstract: PURPOSE:To facilitate control among respective members and to reduce the number of parts and the production cost by irradiating a diffraction grating with the reproducing light to record interference fringes on the diffraction grating so that a specific reproducing condition is satisfied and obtaining a least circle of confusion. CONSTITUTION:Two spot light sources which emit light whose wavelengths are different from the wavelength of the light emitted from a light source for reproducing are provided, and a first spot light source is arranged in a prescribed position on the optical axis, and a second spot light source is arranged in a prescribed position on an axis which forms a prescribed angle with the optical axis, and the diffraction grating is irradiated by both spot light sources to record interference fringes. In this case, the reproducing condition satisfies an inequality I. Consequently, a part of the light transmitted through the diffraction grating element is diffracted to become astigmatic light, and a satisfactory least circle of confusion is formed in a position distance from the origin. Thus, the control among respective members is easily performed.

Title: Private branch electronic exchange having setting function of call signal
Inventor: URUSHIBATA YUMI
IPC: H04M3/42
Filed: 1991-09-05
Abstract: PURPOSE:To discriminate a call from a specific caller depending on a call tone. CONSTITUTION:For example, a telephone set 1 dials a special number and dials an extension number of a telephone set 2. In this case, a CPU 4 receives the extension number of the telephone set 2 and registers it to a storage circuit 5. After the registration above, when the telephone set 2 dials, e.g. the telephone number 1, the CPU 4 checks whether or not the extension number of the telephone set 2 is stored in the storage circuit 5. In this case, since the extension number of the telephone set 2 is stored in the storage circuit 5, the CPU 4 controls a switch 9 next to connect a subscriber circuit 7 and a special call signal generating circuit of a call signal generator 6. Thus, the special call signal is sent to the telephone set 1 through the switch 9 and the subscriber circuit 7 and a special call tone is sent from the telephone set 1. Thus, the user of the telephone set 1 listens to the call tone to recognize the call from the telephone set 2.

Filed: 1992-07-31
Abstract: PURPOSE:To accurately determine an optimum contact angle of a magnetic head by bringing the gap part of the magnetic head into contact with a mag netic tape to adjust the contact angle by the turning operation with the gap part as the center of turning. CONSTITUTION:A magnetic head 10 is moved in the vertical direction to retrieve the vertical position where the amplitude of a reproduced output waveform is maximum, and the optimum vertical position is determined. A THETALR axis goniostage 11 is operated in the optimum vertical position by a lever 17, and the head 10 is turned clockwise and counterclockwise with a gap part (g) as the center to change the contact angle little by little. Since the contact angle is adjusted with the gap part (g) on a magnetic tape 9 in this manner, the other axial operations are unnecessary. The contact angle which maximizes the amplitude of the reproduced output waveform is retrieved to determine the optimum contact angle. Further, the head 10 is projected and drawn back to retrieve the projecting position for a maximum reproduced output, thus determining the optimum projecting position.
