Title: Tape cassette
Inventor: KANEDA HIROSHI
IPC: G11B23/087
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To prevent the assembling of brake members by mistaking the right and left ones by providing a lower case with erroneous insertion preventive ribs near its brake shafts so that the ribs do not come into contact with the brake members when the members are correctly assembled and that the ribs come into contact with the brake members to prevent the assembly thereof in case of erroneous assembly. SOLUTION: The brake member 7b on a take-up side reel has a projection in the position evading the rib 12 existing at the base part of a brake insertion shaft 10 and, therefore, the interference does not arise and the insertion of the take-up side member 7b to the correct position is possible at the time of assembly. The brake member 7a on the supply side reel is similarly constituted. If the supply side member 7a and the take-up side member 7b are mistaken, the insertion of both into the correct position is not possible and springs 8 are no more mountable at the projecting parts of the respective insertion shafts 10 and, therefore, the mistake may be noticed. In a separate embodiment, the diameters of the brake member insertion shafts disposed at the case and the holes of the brake members are varied.

Title: Bar code reader
Inventor: NAKAMURA KENICHI
IPC: G06K7/10
Filed: 1987-10-07
Abstract: PURPOSE:To eliminate the need of a light emitting element used conventionally and to prevent the disconnection fault of a flexible cable by using a laser beam projected from a laser pipe for both detection of goods and reading of a bar code. CONSTITUTION:A laser beam is guided from a reading window 2 in the upper direction of a reading surface by a first light guiding means 32 and by a second light guiding means 7, the laser beam is guided to a light emitting part 51. When the goods passes through the prescribed position of the upper direction space of the reading surface, the laser beam projected from the light emitting part 51 is interrupted, detected by a light receiving element and the bar code of the goods to pass through the upper direction space of the reading surface is read by the laser beam. Thus, since the laser beam projected from a laser tube 31 can be used for both detection of the goods and reading of the bar code, the light emitting element used conventionally is made unnecessary, and the disconnection trouble of a flexible cable can be prevented.

Abstract: PURPOSE:To achieve a higher separation accuracy by arranging an effluent discharge tube, a liquid level detector and a plurality of interface detectors each having a flow rate adjustor at the bottom and top of a filling column and on the side thereof to keep a thickness of a liquid holding layer constant. CONSTITUTION:A plurality of interface detectors 18 are disposed on the side of a filling column 1 at a fixed interval and as the boundary between a filling layer 2 and a liquid holding layer 3 varies, a digital signal is outputted from the element 18 adjoining on the layer 2 to be converted into an electrical signal I1 with a controller 8. In a current generator 10, a value of a thickness to be held by the layer 3 is set to be outputted to an addition operator 11 as electrical signal II, which is added to the signal I1 inputted to be outputted to an adjustor 12 as electrical signal I3. By a liquid level detector 5, an electrical signal corresponding to a liquid level-to-level distance between a liquid level detector 27 preset and the layer 3 is outputted according to a change in a liquid level to be outputted to the adjustor 12 as signal I4. Thus, the adjustor 12 sends a difference I between the signals I3 and I4 to a flow rate controller 6 and a flow rate adjustor 7 to regulate a pump adjusting valve, thereby keeping a thickness of the liquid holding layer 3 constant.

IPC: H03F3/343
Filed: 1986-10-24
Abstract: PURPOSE:To obtain a current output with high accuracy over a wide output voltage range with a high output resistance by making drain-source voltages of transistors (TRs) deciding a ratio of an input current to an output current equal to each other so as to eliminate the error due to the channel length modulation. CONSTITUTION:N-channel MOS TRs are all used and the relation between an input current Iin and an output current Iout is designed to be made identical. The ratio W/L of the channel width to the channel length of a MOSFETM 6 only is 1/4 in comparison with that of the other TRs. The same input current is fed to all the TRs in this current mirror circuit. Since the drain-source voltage of the MOSFETs M1, M3 deciding the ratio of the input current in to the output current Iout is both DELTAV, the effect of the channel length modulation onto the MOSFETs M1 and M3 is identical thereby enabling the input output current ratio to be decided with high accuracy.
