Title: Method and device for separation of bundled and piled sheet paper
Inventor: FUIRITSUPU UISUMURAA
IPC: B65H3/62
Filed: 1993-03-05
Abstract: PURPOSE: To enable automatization of separating operation of sheets of paper stacked in a ream by specifying the pressure force applied on the ream against a curved surface for separating sheets of stacked paper, the method for moving the pressure application line, the rate of this move and the like and sending a ream with a fine movement. CONSTITUTION: A pressure is applied on a ream R of sheets of paper against a rising member 16. The ream R is positioned on its center about below the axis line 43 of a cylinder 41. Simultaneously members 13 and 14 are lowered and separated from each other below a board 1. A piston 2 supports the ream R against the cylinder 41. Then, rollers 61 and 62 lifts the ream R and applies a certain pressure onto the cylinder 41. The piston 2 is lowered. The roller 61 goes far from the roller 62 in the direction of the arrow F1 and the roller 62 moves in the direction of the arrow F2 symmetrically. When the rollers 61 and 62 moves over the edge of each sheet, the sheet is released from the ream in the direction of the board. Sheets are released successively because the rollers moves continuously.

Title: Immersion type device for measuring specific gravity of liquid
Inventor: MUTSUKAWA KAZUO
IPC: G01N9/24
Filed: 1991-03-11
Abstract: PURPOSE:To facilitate operation, washing and maintenance and to enable highly-precise measurement of the specific gravity by a method wherein a change in the reflectivity of a prism face due to a change in the refractive index of a measuring liquid is determined on the basis of measurement of the quantity of sensed light of a measuring light-sensing part. CONSTITUTION:A prism 10 has a prism face 8 slanting at an angle of 30 deg., for instance, to the optical axis X of a measuring light-emitting diode 14 intersecting a plane of incidence perpendicularly and a total reflection face 30 slanting at an angle of 60 deg., for instance, to the optical axis Y of a measuring photosensor 16. A bundle of rays emitted from the diode 14 is partly reflected on a critical plane on the prism face 8 and partly transmitted therethrough. The ratio between the quantity of the reflected light and the quantity of the transmitted light changes in relation to the refractive index of a liquid in which the prism face 8 is immersed, according to the rule of a critical angle. The reflected light by the prism face 8 is then totally reflected by the total reflection face 30 and reaches the sensor 16. A detected value of the sensor 16 is corrected by outputs of a reference photosensor 20 and a temperature sensor 24, the refractive index is computed by a prescribed arithmetic formula and the specific gravity is computed from the refractive index.

Filed: 1990-02-26
Abstract: PURPOSE:To enable control regarding a musical sound by a new operating method by controlling the generation of the musical sound or musical sound elements of the generated musical sound according to a physical quantity detected by a physical quantity detecting means. CONSTITUTION:A cord member 12 is drawn in a housing 10 by a drawing-in means with a specific force and an operating member 15 inhibits the cord member 12 from entering a musical instrument main body housing at an outer end. When a player grips the operation member 15 and draws it out of the musical instrument main body housing, the cord member 12 moves outward corresponding to the drawing force, but when the drawing force is weakened, the cord member 12 moves into the musical instrument main body housing through the operation of the drawing-in means. Then a physical quantity detecting means 19 detects a physical quantity regarding both the movements of the cord member 12. Consequently, the generation of the musical sound or musical sound elements of the generated musical sound of the electronic musical instrument are controlled according to the detected physical quantity.

Title: Charging circuit
Inventor: OSANAI KATSUTOYO
IPC: H02J7/10
Filed: 1990-02-26
Abstract: PURPOSE:To shorten recharging time of a battery by actuating a contact connected with a power supply based on a signal, to be produced upon turn ON of the power supply, having duration proportional to and shorter than the OFF interval of the power supply thereby charging the battery. CONSTITUTION:Upon turn OFF of a power supply, a gate 7 closes and the output from an oscillation circuit 4 is subjected to 1/100 frequency division through a frequency dividing circuit 5 and fed to the adding terminal of an up/down counter 3. Upon turn ON of the power supply, a gate 6 closes to feed the output from the oscillation circuit 4 to the down count terminal of the up/down counter 3 thus causing abrupt decrement of count. Since 0 appears at the output terminal OUT during decrement operation, a relay 9 functions to close a contact 10 thus charging an Ni-Cd battery 1 quickly through a resistor R1. When the count in the up/down counter 3 goes 0 subsequently, 1 appears at the output terminal OUT and the relay 9 is released to open the contact 10.
