Title: Pickup of electric musical instrument
Inventor: BIZEN NAOTO
IPC: G10H3/18
Filed: 1992-10-20
Abstract: PURPOSE:To boost an output voltage without being affected by a guide electromagnetic wave and to obtain signals with satisfactory attensuation characteristics and frequency characteristics by providing magnetic resistors at the respective counter positions of plural strings so as to convert the change of magnetic flux caused by the vibrations of strings to an electric signal. CONSTITUTION:In the pickup of an electric musical instrument which changes an interval between the upper edge part of a yoke 3 and a string 5 by vibrating the string 5 to change the magnetic flux flowing through the magnetic circuit of a permanent magnet 1, and concerts this change of magnetic flux into the electric signal to fetch the change, a magnetic resistor 6 is arranged at a place where the magnetic flux is changed. By arranging the magnetic resistor 6, the resistance change can be obtained in accordance with the magnetic flux change and as a result, the electric signal based on the voltage change can be fetched from an output terminal as the output signal of the electric musical instrument. Further, since the magnetic resistors are arranged one by one for each string at the counter position where the change of magnetic flux is largest, the large output voltage can be obtained.

Title: Display device for elevator
Inventor: YOKOYAMA YASUHIRO
IPC: B66B3/02
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To make securable the luminance of a display character at the time of starting operation even after a long-time operation so as to make the display character easily viewable, by automatically correcting the degradation with year in the luminance of the display character on the basis of an individual lighting time of each dot LED. SOLUTION: When floor display data are inputted into a communication circuit 17, an MPU 11 displays characters on a floor-indicator/direction light 14, while a timer 15 counts reference time at any time. The MPU 11 calculates the difference between a counted value of the timer 15 at the time of switching of display contents in the floor-indicator/direction light 14 and one at the time of switching of next display contents, adds the calculated difference to data in a storage area of a memory 30 corresponding to each dot LED, and repeats these operations hereafter. By referring to a lighting time of each the dot LED stored in the memory 30, the MPU 11 can calculate a present luminance of each the dot LED on the basis of a luminance change caused by secular degradation of the dot LED. On the basis of the calculated present luminance, the MPU 11 lengthens a pulse width of each segment signal by a width corresponding to the degradation in the luminance of the display character so as to make the luminance of the display character brighter.

Title: Audio signal switching circuit
Inventor: OKUMURA NAOJI
IPC: H04N7/015
Filed: 1989-11-27
Abstract: PURPOSE:To switch an audio signal automatically without need of an external switching signal by switching an inputted audio signal and a clock sequentially and stopping the switching when the audio synchronization is detected. CONSTITUTION:When a counter 4 starts counting from 0, a selector 3 selects an audio signal 1 and a clock 1 and they are outputted. When no synchronizing signal is detected by an audio synchronizing detection circuit 2, a high level is outputted as a control signal. Then an AND circuit 5 takes AND with a clock A, but since the control signal is left at a high level, the clock A is outputted as it is. Then the counter 4 counts up the clock (B) and the output goes to 1 and the selector 3 selects the audio signal 2 and the clock 2 and the result is outputted. Similarly, when no audio synchronizing signal is detected, the counter output goes to 2, and the audio signal 3 and the clock 3 are selected. When the audio synchronizing signal is detected, the control signal goes to a low level, the circuit 5 stops the clock A and the output goes to a low level. Then the selector 3 selects the signal 3 and the clock 3 continuously.

Abstract: PURPOSE:To perform smooth humidification of a storage chamber by a method wherein a zeolite porous material is disposed on wall surfaces, by which an inner box is composed, in a manner to front on the storage chamber, and drain from a cooler is fed to the porous material. CONSTITUTION:A plateform porous material 20 is disposed to side walls 3D-3F by which a part of an inner box 3 is composed. A substance prepared by processing zeolite green tuff in a plateform state is used as the porous material 20. Further, a film 30 formed of a polyethylene film is mounted on the surface on the cold air circulating space 11 side of the porous material 20. The film 30 has fine air holes and permeates metabolism gas but limits the passage of a moisture content. Drain from a cooler 12 is fed to the porous material 20 in a topmost layer and penetrates through capillary phenomenon and is held with high efficiency. The drain also drops and penetrates the lower porous material 20. When humidity in a storage chamber 10 is reduced, a moisture content is diverged in the storage chamber 10 and besides diffusion of the moisture content to a space 11 is limited by the film 30 and indirect cooling is effected. Thereby, the interior of the storage chamber 10 is maintained at a constant temperature constant humidity state (humidity of 90-95%) and deterioration of quality of a stored article is suppressed.
