Title: Keyboard device
Inventor: TOMITA IWAO
IPC: G10C3/12
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a key touch feeling approximated to an acoustic piano. SOLUTION: A key 2 is attached onto a keyboard chassis 1 so as to be vertically turned, a rubber switch 20 having first-third switch parts 20b-20d is provided corresponding to this key 2, and a support 21 provided on the keyboard chassis 1 is equipped with a leaf spring 22, to which an abutting part 25 of a hammer arm 5 is abutted, and an electromagnet 23 for attracting the leaf spring 22.  Therefore, when the abutting part 25 of the hammer arm 5 bends the leaf spring 22 and goes over it at the time of keying, a click feeling can be applied, musical sounds are generated in response to an ON signal outputted by the second switch part 20c at such a time, sounding is enabled simultaneously with the application of the click feeling and since the electromagnet 23 maintains the leaf spring 22 in bending and deforming state, no click feeling is applied in the return process of the key 2 so that the key touch feeling much more approximated to that of the acoustic piano can be provided.

Abstract: PURPOSE:To enable the control of the optimal condition at any time and improve the snow removing efficiency by setting the optimal control characteristic for respective combinations of travelling speed stage, and speed stage of a snow removing device and snow removing cross-sectional area, and performing control on the basis of them. CONSTITUTION:The optimal control characteristic for respective conditions corresponding to the combination of speed stage of a travelling transmission 3, speed stage of a transmission 7 for a snow removing device and snow removing cross-sectional area are set on the basis of theory and result of experiment. When the load of the snow removing device 9 is light and the engine speed N is larger than the reference speed N0, the HST swash plate angle theta is maintained at a constant value theta0 so as to prevent the higher speed than required. When the engine speed N is between the reference speed N0 and the engine speed NL unsuitable for snow removing work, the HST swash plate angle theta is reduced in proportion to the lowering amount of the engine speed N. Further, when the engine speed N is fallen below the engine speed NL, the HST swash plate angle theta is made 0.

Title: Digital value converter for resistance value
Inventor: IKOMA MITSUGI
IPC: G01R27/02
Filed: 1983-04-22
Abstract: PURPOSE:To obtain a correct digital value of a resistance value by a method wherein a frequency of a non-stable multi-vibrator comprising resistances to be measured and capacitors or an oscillator is counted and divided by a value when a reference resistor is connected. CONSTITUTION:The pulse width T2 of a non-stable multivibrator 100 comprising transistors 14 and 15, resistances 9-11 and capacitors 12 and 13 is proportional to (resistance value of a resistance 5)X(capacity of the capacitor 12), for example when a switch 1 is closed and switches 2-4 opened. When the switch 2 is closed and the others opened, the pulse width T2 is obtained proportional to the resistance value of a resistor 6. Therefore, when the resistance 5 is used as reference, the other resistances are obtained by determining the ratio of a digital value obtained with a counter 300 with an arithmetic processor such as microcomputer. Thus, digital values can be found for resistance values of resistors.

Title: Detecting device for flow rate of granular object
Inventor: HIRAYAMA HIDETAKA
IPC: G01F1/00
Filed: 1989-03-24
Abstract: PURPOSE:To improve the detection accuracy by covering a piezoelectric element for converting a collision of a granular object to an electric signal, and a signal processing unit for outputting a flow rate detecting signal, based on the electric signal, with a metallic shielding body. CONSTITUTION:A piezoelectric element 1 for converting a collision of a granular object to an electric signal is attached to the reverse side of the upper part of a metallic case 2, and the granular object is detected by the surface side of the upper part of the case 2. Also, a signal processing unit 3 is inserted into the case in a state that the outside periphery of a printed board 4 is attached to the bottom part of a flange 5 of the case 2. The reverse side of its substrate 4 is covered with a metallic shielding plate 6 through an insulator. Accordingly, when the case 2 and the shielding plate 6 are grounded, the element 1 and the unit 3 are shielded magnetically and electrostatically, therefore, an external noise generated by a motor and a relay is not guided to a connecting line for grounding the element 1 and the unit 3, and the unit 3. As a result, a feeble electric signal from the element 1 is processed by the unit 3 and can be fetched without being influenced by the external noise.

Title: Reflecting mirror for fluorescent lamp of inside illuminating sign
Inventor: OTSUKA KATSUMI
IPC: G08B5/32
Filed: 1994-03-07
Abstract: PURPOSE:To radiate light at high radiation efficiency and lessen the unevenness of brightness on a screen by making main light beams coming out of a fluorescent lamp tube reach the screen, the reflected light beams cross in front of the fluorescent lamp tube, and the reflected light beams with different incidence angles impinge upon any points on the screen. CONSTITUTION:Cylindrical or ellipse barrel mirror faces having a radius or the major axis larger than the diameter of a fluorescent lamp tube are set symmetrically at proper gap to cross a part of reflected light beams in front of the fluorescent lamp tube. Light beams except those which go toward a screen directly from the fluorescent lamp are reflected in various directions by the cylindrical or ellipse barrel mirror faces composing a reflecting mirror. The directional distribution of the reflected light beams, that is luminous intensity of the reflected light on the screen, can be adjusted by properly setting the radius or the major axis of the cylindrical or ellipse barrel mirror faces and the distance from the symmetric plane. In the figure, 0 stands for the symmetric plane, 1, 1' for inner cylindrical mirror faces having larger radius 3 than the diameter of the fluorescent lamp tube 2, and 4, 4', 5 respectively for the centers of the mirror faces and the screen. The faces 1, 1' are connected with each other by a flat mirror face 6.

Abstract: PURPOSE:To enable the conveying direction of a sheet material to be stably reversed by providing an auxiliary rotor which has the diameter larger than that of conveying rotors, and is capable of waving the sheet material in a counterrotating section in a copying machine and the like. CONSTITUTION:A form, one side of which has been copied, is conveyed along the inner side of a change-over guide 71 while it is held by both flange rollers 65 and 67 and a press roller 73, and is waved by flanges 65L, 65R, 67L, and 67R allowing it to be nervous. Then, the tip end of the form strikes against a conveyor guide 53, the form is bent to an intermediate tray 155 side, and is forwarded into a switch-back path 21. Then, when the rear end of the form comes out of the press roller 73, the form is swung to the conveyor guide 53 side because of its nurve and gravity, rollers 77 and 81 are rotated by a signal from a sensor 61, and the form is reversed and conveyed to a discharge roller 87 side. Thus, this configuration allows the conveying direction of the sheet material to be stably reversed.

Abstract: PURPOSE:To effectively and surely eliminate an adhering substance irrespective of a shape and length of a pneumatic tube by bringing dry ice grains to pneumatic carrying into the pneumatic tube with regard to a method for eliminating nuclear fuel powder such as plutonium, etc., adhering to the inside of the tube. CONSTITUTION:At the time of pneumatic carrying of nuclear fuel substance powder 1, powder 1 in a glove box A is brought to pneumatic carrying to a cyclone 3 in a glove box B, in which a solid-gas separation is executed, and only the solid powder 1 is collected in a hopper 4. This pneumatic carrying is executed by setting the pneumatic tube 2, the cyclone 3 and the hopper 4 to negative pressure by a blower 5 in a glove box C. Also, in this process, the powder 1 adheres or it is stagnant onto the inside surface of the pneumatic tube 2, the inside surface of the cyclone 3, the inside surface of the hopper 4, and the surface of a filter 6. Therefore, instead of the powder 1, dry ice grains are brought to pneumatic carrying into the pneumatic tube 2 in the same way, and by its impact force, the powder is peeled off and eliminated effectively. Its specific gravity is 1.56 and its hardness is low and no damage is given to an apparatus, etc.
