Title: Fingerprint image detector
Inventor: KAWASAKI KOJI
IPC: G06T1/00
Filed: 1987-03-17
Abstract: PURPOSE:To detect a fingerprint image even when a finger is wetted with water by setting the angle of a light incident on the incident surface of a prism to the angle larger than an angle which cannot be transmitted to a water layer by the total reflection on the reflecting surface of the prism. CONSTITUTION:Parallel rays 30 are incident on the incident surface (b) of the prism 2, reflected on the reflecting surface (a), received by a camera 3 and transferred to an image pickup processor 4. The water layer 10 is present between the recessed part 5 of the fingerprint and the reflecting surface (a) and the layer 9 of the sweat and the oil of the surface of a finger is present between the protruding part 6 of the fingerprint and the reflecting surface (a). When the angle of incidence theta4 of the parallel rays 30 is made larger than the angle at which the light is not transmitted to the water layer 10 with the total reflection of the light on the reflecting surface (a), the light is totally reflected on the recessed part 5 of the fingerprint, a part thereof is reflected on the protruding part 6 of the fingerprint, and a residual part is transmitted. Thereby, the fingerprint image can be clearly detected.

Title: Free cutting brass
Inventor: OSAKO TOSHIYUKI
IPC: C22C9/04
Filed: 1990-03-12
Abstract: PURPOSE:To reduce machining resistance and to improve machinability, particularly piercing property, by specifying iron content and limiting respective contents of Si and P in a free cutting brass having a composition in which Pb is added to a Cu-Zn alloy with a specific composition. CONSTITUTION:This free cutting brass has a composition which consists of, by weight, 56.0-63.0% Cu, 1.8-4.5% Pb, >=0.01% Fe, and the balance Zn with inevitable impurities and in which the contents of Si and P are regulated to <0.001%, respectively. In this brass, Fe is practically inevitably introduced into the material though Fe in itself is an impurity, and, if Fe content is <0.01%, the possibility of the formation of a particularly hard compound dispersed phase can be minimized even if Fe coexists with Si and P. However, if Fe content is >=0.01%, a hard compound dispersed phase is formed when Si or P content is >=0.001% and, as a result, the wear of tools used for material working is increased.

Abstract: PURPOSE:To surely return a card to a customer even at the time of card jam or a power failure by controlling a lock means so that the energizing operation is unlocked at the time of the occurrence of a power failure or a device abnormal operation. CONSTITUTION:In the case of normal transaction, a hook 6 is stopped at the rear end of a card tray 1. If a power failure occurs, a motor 9 is stopped, and power supply to a solenoid 11 is cut off. Consequently, a latch 10 is turned upward by the action of a spring and is disengaged from the hook 6. The hook 6 is energized backward to the tray 1 by the tensile strength of a tension spring 7 to inversely carry the tray 1 to an insertion part. Since power supply to a solenoid 7 is cut off also, a clamp 2 is separated from a card 4, and the card 4 can be pulled out any time by the customer. If abnormality occurs in the device, power supply to the motor 9 and solenoids 11 and 17 is cut off by the control of a control part. Consequently, the card tray 1 is moved to the customer side by the tensile strength of the tension spring 7 in the same manner as the occurrence of a power failure.

Title: Oxygen concentration detector
Inventor: ASAKURA MASAHIKO
IPC: G01N27/409
Filed: 1986-03-19
Abstract: PURPOSE:To prevent a possible blackening phenomenon, by a method wherein a current value command to a delay means is stopped when a voltage between electrodes of a battery element exceeds a first specified value and when it exceeds a second specified value, a pump current is reduced sharply. CONSTITUTION:A constant current is supplied to between electrodes of an oxygen pump element 1. A current command indicating a pump current value from an Ic output end of an air/fuel ratio control circuit 31 is supplied to a voltage division circuit 36. As a voltage Vs rises between electrode plates 7 and 8 of a battery element 2, an output voltage Vs' of a non-inversion amplifier 30 goes up and when it exceeds a first specified value, an output of an operational amplifier 41 inverts from a low to high level to turn a transistor 51 ON so that a connection line between the circuit 36 and an integrating circuit 39 will be almost equal to the earth potential. An electric charge of a capacitor 38 flows to the earth to reduce a pump current gradually with a gradual drop in a reference voltage. As the voltage Vs exceeds a second specified value until the pump current rises to attain a range of causing blackening phenomenon, a transistor 13 is turned OFF to reduce the pump current sharply.

Title: Direct teaching mode switching system for robot
Inventor: WATANABE KAZUNORI
IPC: G05D3/12
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To automatically perform mode switching without any awareness on a part of an operator by performing automatic switching between direct teaching and a usual mode according to a size relationship among an operating force detected by a force sensor, a first threshold value, a speed in a hand side and a second threshold value. SOLUTION: By paying attention to the force sensor of an operation device, a mode switching section 10 automatically switches the mode of a direct teaching mode based on force information F obtained by the force sensor and the hand tip speed of a robot calculated by a hand tip speed calculation section 11. In other words, when a current operating force F detected by the force sensor exceeds a first threshold value Fmin, switching is made to the direct teaching mode. Thus, the direct teaching mode is automatically set only by touching the operation device, and setting returns to a usual mode by releasing the hand, and thus an operator performs direct teaching without any awareness.
