Title: Growth method of crystal
Inventor: ROBAATO JIYOSEFU MAKURERANDO
IPC: H01L21/20
Filed: 1990-09-10
Abstract: PURPOSE:To control an atomic step structure on the surface of a grown crystal thin film and to control a step flow during a crystal growth operation by a method wherein electrodes are installed at ends of a crystal substrate and a pulse current whose positive-negative polarity, pulse intensity, pulse width and repetition frequency have been controlled independently of each other is made to flow to the electrodes. CONSTITUTION:After a substrate cleaning process 11, electrodes to which an electric current is made to flow are installed at both ends of a cleaned crystal substrate; after that, a contamination layer and an oxide film on the surface of the crystal substrate are removed by a heating operation in a vacuum or in an inert gas atmosphere or by an etching operation by using a reactive gas; a clean surface is obtained. The heating operation in this case can be executed by means of a heating operation by applying a DC or AC electric current through the electrodes, by means of a heating operation by using a heater installed separately, an electron beam or infrared rays or by using a heating means used in conventional cases. Then, a current pulse is made to flow to the crystal substrate through the electrodes, the pulse is applied, and a crystal growth operation is executed by an epitaxial growth method. At the pulse current, three of the peak intensity, the width and the repetition frequency for the pulse are combined. Thereby, the movement of surface atoms and the degree of setting freedom of a temperature at the crystal substrate can be made very large.

Title: Image pickup element, manufacture of the same and aligner
Inventor: SUZUKI JUNJI
IPC: H01L21/027
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To enhance sensitivity of an image pickup element. SOLUTION: A microlens 20 is formed respectively to have a space SP on the array of a plurality of light receiving portions PD formed on a substrate S of a CCD.

Filed: 1988-09-21
Abstract: PURPOSE:To drive a solenoid in the minimum required excitation time by providing a switching means stopping the excitation of the solenoid based on the output signal of a detecting means detecting the current flowing in the solenoid. CONSTITUTION:When a switch 3 is closed to drive a solenoid valve if a load is large, the movement of a plunger is slow, the voltage value VR reaches the preset voltage V0 in the time t1, a switch driving circuit 6 opens the switch 3 via a comparator 5, and the excitation is stopped. On the other hand, if the load is small, the movement of the plunger is quick, the voltage value VR reaches the preset voltage V0 in the time t2 (t2<t1), and the excitation is stopped. The solenoid can be invariably driven in the minimum required excita tion time, thus a solenoid valve driving circuit with excellent power consumption can be provided.

Title: Wire bonder
Inventor: YOSHIDA HARUO
IPC: H01L21/60
Filed: 1986-10-06
Abstract: PURPOSE:To improve position accuracy and to implement high speed movement of a head, by arranging a camera and a recognizing device on the head, thereby preventing deviation in vibrations of the head and the recognizing device. CONSTITUTION:A camera 4 is horizontally mounted on a bonder head 1. A lighting device 6 is mounted on the tip side of the camera 4, which is lighted since light from a bonding position is refracted at a right angle. Since the bonding position is projected onto the camera on the bonder head in this way, the position of the center of gravity of a recognizing device can be arranged on the head. The vibration of the recognizing device at the time of movement of the head can be tuned to the vibration of the head. Thus the deviation in detection of the bonding position due to the vibration of the recongnizing device is prevented.

Title: Building and passing method for solving traffic jam caused by concentrated vehicles in crossing
Inventor: CHIN KENGEN
IPC: E01C1/04
Filed: 1998-08-11
Abstract: PROBLEM TO BE SOLVED: To provide a building and a passing method to solve a traffic jam caused by cencentrated vehicles in a crossing, which can be installed regardless of topography and the magnitude of space, and perfectly avoids a traffic jam in a crossing to smoothly let vehicles going straight pass. SOLUTION: In a building and a passing method to solve traffic jam caused by concentrated vehicles in a crossing, the building is chiefly installed in main roads J, K and branch roads M, L to avoid the traffic jam. The building is used in a road in which vehicles concentrate on an elevated bridge A, B, C or in an underground tunnel. Accordingly, vehicles which go straight can run straight in a crossing without making a detour, and further, vehicles turning right or left make a detour or U-turn by using the building installed in the opposite lane and hence traffic jam or accidents which arise in the crossing can be prevented. Since the building is erected on the roads, there is no influence of the building even in a narrow space and the method is adaptable for any topographic location or space.

Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To attain miniaturization by decreasing a length of a radiation section projected from an opening of a waveguide in the case of supporting a dielectric feeder to the opening of the waveguide. SOLUTION: A trumpet shape is adopted for a shape of a radiation section 5b projected externally from an opening of a waveguide 1 in the primary radiator where a dielectric feeder 5 is supported to the opening of the waveguide 1 and a plurality of annular groove 7 with a depth of about 1/4 of a wavelength λ0 of a radio wave propagated through air is formed to an end face of the radiation section 5b.

IPC: B41F21/04
Filed: 1987-09-25
Abstract: A sheet gripper for a rotary press is provided having a hooked gripper finger pivotably connected at its lower end to a clamping element, and a roller disposed upon the gripper finger is biased against the guiding surfaces of a finger support element to ensure smooth changes from open and closed gripper finger positions, substantially without any vibrational motion or displacement resulting in the plane of sheet motion. Preferably, a compression spring is mounted in the clamping element to bias the roller against the gripper support element, the element having a rectilinear guide surface disposed substantially perpendicularly to a retaining surface, and a cam surface which extends upwardly and inclined outwardly from the rectilinear guide surface. Upon oscillation of the gripper shaft, the roller is guided along the rectilinear guide surface and cam surface, thereby defining accurate gripper finger motion.
