Title: Glass forming device
Inventor: SUGURO MASAHIKO
IPC: C03B11/06
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To freely oscillatably support a bottom die with respect to a table by disposing an oscillating means between this table and the bottom die. SOLUTION: Even if the table inclines at the time of pressing, this inclination is not transmitted to the bottom die 12 and is absorbed by a gimbal mechanism 16 and, therefore, the posture of the bottom die 12 does not change. Then, pressing may be executed in the aligned state of the axial centers of a plunger and the bottom die 12 and, therefore, the fissure and crack which occur in glass formed goods are prevented.

Title: Self-traveling vehicle
Inventor: WATANABE TOSHIHIKO
IPC: B65G1/04
Filed: 1987-01-13
Abstract: PURPOSE:To stop a self-traveling vehicle at a right position, by mounting a bar code reader on the self-traveling vehicle, and attaching a bar code label at a stop position. CONSTITUTION:The bar code label BL is attached on the projecting part of a position detecting plate 5, and a value is increased one by one in a traveling direction. A position detector 2 detects the projecting part of the plate 5, and the self-traveling vehicle 1 stops when the number of times of detection coincides with the number of the projecting parts of the plate 5 between a position where the vehicle has been stopped and the position desired to move. After stop, the BL is read by the bar code reader 3, and a difference between the value of the BL of the position desired to move and a read value of the BL is calculated. When the difference is positive, the vehicle is moved in the traveling direction, and when it is negative, it is moved to the position where projecting part of the plate 5 is detected by the number of times of the difference in a direction opposite to the traveling direction, and the BL is read again, and the above operation is repeated until the difference goes to zero. In such a way, it is possible to stop the vehicle at the right position.

Title: X-ray apparatus
Inventor: TSUCHIYA AKIRA
IPC: H05G1/32
Filed: 1984-01-18
Abstract: PURPOSE:To vary an X-ray tube voltage without increase of ripple contained in an X-ray tube voltage not only by controlling the timing of applying a DC voltage to a resonant circuit but also varying a DC voltage applied to the resonant circuit. CONSTITUTION:An X-ray tube voltage can be varied by changing the change- over operation of a switching means 21 and a repetition frequency of timing signals outputted from a control means 19. Namely, an X-ray tube voltage is varied by presetting a DC voltage to be applied to a resonant circuit (primary winding 6a and capacitor 5 for resonance) with the switching means 21 before irradiation of X-ray and then changing the repetition frequency of timing signal outputted from the control means 19. As explained above, an X-ray tube voltage can be lowered up to a desired value, without setting the thyristors 12 and 14 to a low ignition frequency, by presetting a DC voltage to be applied to the resonant circuit with the switching means 21 (for example, setting to a low voltage). Accordingly, ripples contained in a low X-ray tube voltage can be reduced as compared with the conventional apparatus and it is superior to taking a picture of bread, for example, which is carried out in the low X-ray tube voltage region.

Abstract: PURPOSE:To obtain a crystal oscillator which is small in a secular change and is excellent in an aging characteristic by performing a heating processing after the crystal oscillator is formed by allowing a semiconductor layer to contact with metallic salt solution and forming an electrode film after the semiconductor layer is made and is activated on a crystal substrate. CONSTITUTION:A prescribed shape extraction type mask 3 is imparted on an artificial crystal substrate 1 and is installed on a hot plate.

Abstract: PURPOSE:To decrease the resistance of a gate electrode, and improve high frequency characteristics, by arranging a plurality of unit gate electrodes of narrow width in parallel, and forming a specified width of gate electrode. CONSTITUTION:A source electrode 2, a drain electrode 3 and a gate electrode 4 are formed on a semiconductor substrate 1, on a specified part of which an active layer is formed. A gate electrode 4 is made of heat-resistant metal like tungsten, and a specified electrode width of 300-2000mum is obtained, by arranging a plurality of unit gate electrodes having a specified width of 10-50mum in parallel. A source electrode 2 and a drain electrode 3 also are formed so as to correspond with the gate electrode arrangement. As a result, even if heat-resistant metal of high specific resistivity is used, the resistance of the gate electrode can be low, so that high frequency characteristics like noise characteristics can be remarkably improved. Further, since it is unnecessary to coat the heat-resistant metal with low specific resistivity metal like gold, the deterioration of Schottky characteristics can be avoided.
