Title: Method and apparatus for measuring object three-dimensionally by light section method
Inventor: HATTORI SHINICHI
IPC: G06T7/00
Filed: 1994-03-24
Abstract: PURPOSE:To decrease the number of cameras required in light section method while enhancing the accuracy in measurement by shifting a pair of slit light and a camera integrally in the longitudinal direction of an object in order to obtain the cross-sectional data at a predetermined pitch and then measuring the object three-dimensionally based on the cross-sectional data. CONSTITUTION:Three sets of image pickup unit comprising slit lights 8a,...,8c and cameras 9a,...,9c are fixed to a gate frame which is then shifted in the longitudinal direction of an object. The object 2 is irradiated with each slit light 8a,...,8c perpendicularly and the cameras 9a,...,9c for picking up the reflected lights are disposed while inclining the optical axes by 45 deg. against the slit. Since the slit lights 8 intersect the object 2 on one plane, the reflected lights enter straight into the camera 9 and thereby the cross-sectional data can be taken in sequentially as the gate frame moves. The cross-sectional data is processed by respective image processors and synthesized by a CPU 13 before being displayed.

IPC: B21D28/36
Filed: 1994-04-18
Abstract: PURPOSE: To facilitate automatic change of a punch by moving the punch horizontally up to an upper position of a mounting hole formed in an upper turret, then lowering the punch, and detecting whether a lower end part of the punch comes into contact with a wall face of the mounting hole during lowering or not to control the lowering operation. CONSTITUTION: When a punch of turret punch press is changed, a punch P for change is gripped by a punch change device, and this punch P is horizontally moved up to an upper position of a mounting hole 91 formed in an upper turret 15a. Next, the punch P is lowered to detect whether a lower end part of the punch comes into contact with a wall face of the mounting hole 91 during lowering process or not. When its contact with the wall face is detected, a height position of the lower end part is measured, and the measured height is compared with a reference height position. When the detected height position is lower than the reference height position, the punch P for change is lowered furthermore.  Moreover, if the lower end part of the punch comes into contact with an upper face of the upper turret 15a while the punch is lowered, a central position of the mounting hole 91 is searched by a fuzzy search method to move the punch P horizontally.

Abstract: PURPOSE:To perform the copy protection of recorded programs or data by judging whether a password is matching with a key code or not at a control means by reading the key code from a disk-shaped recording medium. CONSTITUTION:First of all, it is judged whether the key code is existent or not from a signal sent from an optical pickup through a servo control circuit, when the password is not coincident, a message showing the impossibility of processing is sent to a main CPU 14 and when it is coincident, a message showing the possibility of processing is sent to the main CPU 14. In such a case, the message can be ciphered and recorded by using a method such as NBSDaTa- Encryption-Standard, for example. Thus, it gets more difficult to recognize the key code from the outside. Otherwise, the key code can be previously recorded in the read only area of a partial ROM disk 804. Thus, the key code can be prevented from being revised by reloading.

Title: Satellite broadcast receiver tuning circuit
Inventor: OKUBO FUYUKI
IPC: H04B1/16
Filed: 1990-03-28
Abstract: PURPOSE:To prevent the occurrence of disturbance even when a 1st intermediate frequency signal of a satellite broadcast and that of satellite communication are transmitted in one cable by making a PIN diode conductive in the case of receiving a low frequency satellite broadcast and making the PIN diode nonconductive in the case of receiving a high frequency satellite communication. CONSTITUTION:A control means 63 is connected to a series resonance circuit via PIN diodes 62, 67 or high resistance resistors 60, 68 respectively and in the case of receiving a satellite broadcast signal of 1, 3 channels, the control means 63 applies a voltage to PIN diodes 62, 67 to make the PIN diodes 62, 67 conductive,thereby attenuating a local oscillating frequency band with a trap circuit 34. In the case of receiving a satellite broadcast signal at a high frequency, the control means 63 applies no voltage to the PIN diodes 62, 67 then the PIN diodes 62, 67 are nonconductive. Thus, the high frequency satellite broadcast signal is not attenuated. Consequently, disturbance is eliminated.
