Abstract: PURPOSE:To reduce the size and the cost by providing a first measuring system for performing a highly accurate positional detection for a specified range and a second measuring system for performing rough positional detection over the entire stroke, and then performing feedback control through switching of signals to fed from these systems. CONSTITUTION:A ultrasonic motor 1 vacuum sucks a wafer 6 by means of a hand 5 which rotates while being fixed to the drive shaft of the ultrasonic motor 1, and carries the wafer 6 from point A to point B. An encoder 2 for measuring the rotary position of the motor 1 is also provided and a linear sensor 8 for securing a light shielding board 7 to the hand 5 and detecting the position of the edge of the light shielding board 7 is further provided. Resolution of the encoder 2 is very rough as compared with that of the linear sensor 8, and the encoder 2 is covered by the capturing range of the linear sensor 8. When the encoder 2 is covered by the capturing range of the linear sensor 8, a controller switches reception of signal from the encoder 2 to the linear sensor 8 and positions the hand 5 at point B with high accuracy.

Title: Formation of antireflection film
Inventor: MARUYAMA KENJI
IPC: G02B1/11
Filed: 1992-09-22
Abstract: PURPOSE:To improve durability and adhesion strength and to prevent cracks by vapor depositing magnesium fluoride MgF2 while irradiating the surface of substrate for optical parts with electron beams. CONSTITUTION:The antireflection film is formed by forming a vapor deposition film consisting of MgF2 on the surface of an optical material to desired thickness. In this process, the film is irrdiated with electron beams. For example, after evacuating a vacuum deposition chamber 1 to 2X10<-5>Torr, a glass substrate attached to a substrate holder 3 and not heated is irradiated with electron beams from an electron gun 4 while MgF2 vaporized from the vapor source 2 is deposited on the glass substrate to the optical thickness of nd=lambda0/4(lambda0=520nm) at about 8-11Angstrom /sec deposition rate. Thereby, durability can be improved due to hardening of a vapor deposition film obtd. by vapor deposition while heating the substrate, and inner stress is mitigated as same as by ion beam assist method, so that the generation of cracks can be prevented.

Title: Runaway preventing device
Inventor: EIANJI HIROSHI
IPC: B25J19/06
Filed: 1985-11-12
Abstract: PURPOSE:To stop a runaway due to the absence of a pulse instantaneously by powering off a motor immediately if a pulse fed back from a pulse generator is absent. CONSTITUTION:For example, if a pulse to be applied to a position detector 6 becomes absent owing to the cause of, for example, the breaking of wiring, the cause of the fault of the pulse generator, itself, etc., the current value which is the output of a current value register 7 is not updated permanently although the motor 4 rotates actually, and the deviation between a command value and the current value is permanently constant, so the motor 4 keeps on rotating in one direction permanently. Then if a pulse to be applied to the position detector 6 from the motor 5 becomes absent, the motor 4 is powered off immediately to prevent the motor 4 entering a runaway state. When this device is applied to a device which is already installed, an interface for matching the device which is an object of runaway prevention and the runaway preventing device is provided at need.

Filed: 1990-09-21
Abstract: PURPOSE:To make the fault trace of an information processor easy by counting up a read address counter by a write pulse when data are written in the whole storage area of a memory by an address comparing means. CONSTITUTION:The initial values of a read address indicating counter 2 and a write address indicating counter 3 are defined as 0, and the address range of a memory 1 is defined 0-n. When input data are changed from D0, D2 to Dn, and a write pulse 6 is inputted at n+1 times, an address comparing means 8 outputs a memory full signal 12. In this state, when the input data 9 are defined as Dn+1 and the write pulse 6 is inputted, the data D0 of the address 0 of the memory 1 are rewritten into the Dn+1, and the value of the counter 2 becomes '1' from '0'. At this time, when a read pulse 7 is inputted, output data 10 are D1, and the value of the counter 2 turns to '2'. Thus, the oldest data of the memory 1 are read out by the read pulse 7.

Title: Code input device
Inventor: SUDO HAJIME
IPC: G06F3/02
Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To realize a simple key input operation and high speed typing by installing a key input part where keys in the range operation by the right hand or left hand are arranged in the same key array as a keyboard. SOLUTION: The code input device has keys obtained by adding two keys to the keys within the range operated by the right hand of a regular keyboard. The range operated by the left hand is made to overlap the keys of the range operated by the right hand in terms of mirror symmetry so that they are overlapped as much as possible. When the keys overlap each other, codes are allocated to one key and individual keys are installed only when they are not overlapped. A right/left system switch key 2 selecting the code of the key to which two codes are allocated and a space input key 3 are also installed. Since the hand/finger function of a human is generally superior in a symmetric operation, key arrangement where the keys of the range operated by the left hand are made to be mirror symmetry can comparatively easily be operated even by the right hand.
