Inventor: ONO TAKASHI
IPC: B41J2/01
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a photodetector capable of being brought to a detectable stable state immediately after driving and always enabling stable detection without receiving the influence from the outside. SOLUTION: The analogue voltage corresponding to the digital data transmitted from an MPU 1701 is outputted from a D/A converter 5 to be converted to impedance by an operational amplifier 7 to be inputted to the base of a transistor 8 and a light emitting element 11 is allowed to light by the current corresponding to base potential. The photocurrent corresponding to the quantity of light incident from the light emitting element 11 flows to a light detecting element 9 and the photocurrent and the potential determined by a resistor 10 appear at an A-point. An A/D converter 4 converts the potential at the A-point to digital data to output this data to the MPU 1701.  When the digital data outputted from the A/D converter 4 is within a predetermined range, the MPU 1001 stores the digital value outputted to the D/A converter 5 in an RAM 1073 and, even at a time of detection, the digital value is outputted to the D/A converter 5.

Title: Individual certification system
Inventor: YAMASHITA KOTARO
IPC: G06Q40/00
Filed: 1986-01-31
Abstract: PURPOSE:To prevent the illegal use of a personal identification symbol even though the symbol is visually stolen by an outside when the symbol is supplied in an operation mode, by securing such a system where the identification symbol is invalidated after it is used and only other symbols are valid. CONSTITUTION:When a user supplies a personal identification number 2 for operation confirming the identify of himself/herself, the coincident registered identification number is obtained in identification number collating processing 32 with reference to recorded information 1. In this case, the coincidence of the identification number is never decided unless the valid indication information is valid (O: valid, X: invalid) even though a coincident registered identification number is detected. When coincidence is obtained between the input number and the registered one, a locked part for a transaction process 33 is released. Thus the transaction processing is possible. When the processing 33 is through, the control is shifted to a valid indication information change processing 34 through the total control 31. Then the valid indication information 21 is invalidat ed (X) for the input number in the processing 34. While the valid indication information 22 that is already invalidated is validated (O).

Title: Punch
Inventor: SADAGATA MASAHARU
IPC: B26F1/32
Filed: 1994-02-15
Abstract: PURPOSE:To heighten the cutting performance of a punch by inserting an inner mechanism frame body into a space between the upper surface and the bottom surface of an outer main body frame, insuring a slit of the main body frame, to be fixed there by means of a locking mechanism together with fitting a push plate in a recessed part through a notched part to be held there in its vertically movable manner. CONSTITUTION:Before punching operation, a push plate 1 is flush with the upper surface of an outer main body frame 3 because the plate 1 is energized upward at its both (right and left) ends by plate springs 10. Since the lower tips of punch blades 7 at this time stay within piercing holes 9a, 9b, they (tips) will not reach a slit (of the punch), and there will be no positional discrepancy between the tips on the right side and that on the left side. During punching operation, since two plate springs 10 placed beneath the push plate 1 are equally and elastcially deformed by pushing pressure, the tips of the punch blades 7 arranged at both ends of the push plate 10 go over the slit to go down until they reach the inside of piercing holes 8a, 8b on the bottom surface side, so that punch holes are made in a document inserted into the slit. With this contrivance, sharpness of the blade in the punching operation, which is determined by two factors: the piercing hole and the punch blade, can be improved.

Abstract: PURPOSE:To prevent deformation and breakage by installing a rolling-contact supporting mechanism which prevents the tilt over a certain angle of a rotor through the rolling-contact with each free edge part of a shaft and the rotor when a lateral swing of the shaft is generated close to a suction port side in comparison to the rotor in a turbo molecular pump. CONSTITUTION:As for a turbo molucular pump equipped with a static vane wheel 5 and a spacer 6 in the pump chamber 3 in a casing 2, a self-lubricating rolling-contact supporting mechanism 19 for preventing the tilt over a certain angle of a rotor 17 is installed in rolling contact at the free edge part of the rotor 17 only the time when a lateral swing is generated on the driving shaft 11 close to a suction port 7 side in comparison to the rotor 17. When the rotor 17 tilts by the angle corresponding to a slit A, the inner peripheral surface 17a of the rotor 17 contacts with a bearing 23, and the tilt in the more degree is prevented. Therefore, the deformation and breakage of a rotary vane wheel in the case when the driving shaft swings laterally can be prevented.

Title: Method for forming solder bump
Inventor: SAGA MISAO
IPC: B23K1/00
Filed: 1979-02-19
Abstract: PURPOSE: To form a solder bump which is characterized by the features that a photoresist is readily removed and damages are not remained in characteristic checking, by melting a solder-plated layer at a specified temperature and curing it, thereafter melting the solder layer at a higher temperature and curing it again.  
     CONSTITUTION: A surface-protecting film 4 is further deposited on an Al wiring 3 which contacts with Si and the window portion of a surface-protecting film 2 on a Si substrate 1, and an underlying metal layer 5 is formed at said window portion. Thereafter, a Pb layer 6 and an Sn layer 7 are stacked by electric plating with a photoresist being a mask. Then, the plated layers 6 and 7 are melted at a temperature less than 320°C, and the photoresist is removed after said layers have been cooled and cured. At this stage, the characteristic check of the element is performed. Thereafter, the temperature is increased again, and the soldering layers are melted again at a temperature higher than the previous melting temperature (e.g., 330W 350°C for the solder comprising 90% of Pb and 10% of Sn), thereby a semi-circular solder bump 8 is obtained. In this constitution, even though damages are given in the characteristic check, the remnants of the damages are not remained.

Filed: 1983-02-07
Abstract: PURPOSE:To perform proper processing when an error occurs by outputting data right before the error occurrence when receiving data has the error and updating output data when the receive data is ceased within a specific time. CONSTITUTION:When no error occurs in the receive signal, an error decision is error generation NO (GO) and a CPU5 performs output processing after fetch processing. If the error occurs to the receiving signal, the error decision is error generation YES (NO GO) and an error frequency decision is NO because of the 1st time, so the CPU5 output data right before the error occurrence after the fetch processing. When the occurrence of the error stops within the specific time after the error occurrence, the error decision is error generation NO and the CPU5 restarts normal output processing after the fetch processing to update the output data. Consequently, proper processing is performed when an error occurs.
