Abstract: There is disclosed an interference spectrophotometer which collects data while monitoring the position of a movable mirror by providing quadrature control to accurately perform coherent addition of data. The spectrophotometer includes a main interferometer, a control interferometer, a sliding controller controlling movement of the movable mirror, an A/D converter converting analog data obtained by the main interferometer into digital form, a register for holding data obtained by one scan of the movable mirror, a memory for accumulating data obtained by numerous scans of the movable mirror, an up/down counter receiving the output signals from two detectors included in the control interferometer, and a decision part. When the counter's value varies, the counter causes the A/D converter to perform its A/D conversion. Then, the decision part checks the counter's value after the A/D conversion.

Abstract: A method for producing a high shock-absorbing automobile bumper with a smooth outer surface.

Abstract: A step-cut insulated gate static induction transistor can accurately make a channel length and a gate length and is excellent as a high speed transistor but is greatly affected by a deviation in mask alignment in the manufacturing process. This invention utilizes the fact that a gate portion formed in a previous processes is used as a mask in a post portion to thereby self-adjustably form the post portion, thus eliminating the influence of the deviation in mask alignment. In addition, a construction has been invented in which a current flowing through a portion apart from a gate between a drain and a source can be restricted. The aforesaid manufacturing method is also used for this improved construction.

Abstract: This invention makes a furnace body divide into two, a pretreating chamber and a nitriding chamber by an opening and closing center wall. After pretreating works to be treated in the pretreating chamber, the opening and closing center wall is opened and the pretreated works are transferred to the nitriding chamber to nitride them. Treatment gas can be saved largely compared with the case that the nitriding is conducted after pretreating works in a furnace which has only a nitriding chamber.

The structure includes plural circular blades which are secured to a concave surface of a shell with some space in the circumferential direction, a core ring which extends along the circumferential direction of the shell and is secured to concave peripheries of the blades. A tab fitting in slot of the shell is formed integrally on the convex periphery of the blade. A tab fitting in a slot of the core ring is formed integrally on the concave periphery of the blade. Ribs extending in the circumferential direction of the shell are only formed on both ends of the convex periphery and concave periphery of the blade. The convex periphery and the concave periphery are brazed to the shell and the core ring respectively.

Abstract: A control device controls the draft for moving the working machine, such as a plow, up or down. The working machine is mounted on a tractor by way of a hydraulic lifting device which is adjusted to the tilling depth predetermined by a tilling depth setter which depends on the increase or decrease of traction resistance detected by a draft sensor. When the lifting machine is changed from the ascending position to the descending position, the draft control function is stopped for a specified short time or a specified short distance to lower the working machine quickly. However, the quick lowering of the working machine is inhibited when the relationship between the detected value by the draft sensor and the preset value by the tilling depth setter is not at the descending position of the working machine.

Abstract: A propulsion apparatus is disclosed for urging a trenching arm forward against the advancing face of an elongate trench being dug by the trenching arm. The propulsion apparatus includes a propulsion member which is engageable with the base wall of the trench such that the trench arm may be urged forward relative to the engaged propulsion member. The propulsion member may then be withdrawn from engagement with the base wall and retracted towards the trenching arm before commencing a further propulsion cycle. The propulsion member is also operable to cooperate with the trenching arm in excavating a starting slot at the beginning of a new trench.
