摘要:
An inspection apparatus for inspecting printed circuit boards on which components have been mounted, wherein a light source that generates a light beam in a concentrated spot fashion is mounted on a rotary object and radiates the beam spot onto the printed circuit board at approximately right angles thereto while the rotary object is rotating, so that the surface of the printed circuit board is scanned by the beam spot. Changes of at least either one of the reflection angle and the intensity of the light reflected from the printed circuit board is detected by photoelectric converters provided on the rotary object, and at least either one of the height and the brightness of the position at which the beam spot and the printed circuit board are intersected is measured, thereby performing the inspection of the printed circuit board.

A random multi-error correcting code having a maximum length block in a packet, for instance a majority logic decodable (272, 190) shortened difference set cyclic code, is used for error correction in a character code broadcasting system. The error correcting ability of this code is increased. The correction is made by decreasing a threshold value, so that the error correcting ability is improved. A framing timing extraction circuit and a phase lock circuit for the framing timing are eliminated, so that the amount of hardware needed is reduced. Preferably, the error correcting code is superposed on the television signal during the vertical blanking period.

A method for producing a high-quality group-III element nitride crystal at a high crystal growth rate, and a group-III element nitride crystal are provided. The method includes the steps of placing a group-III element, an alkali metal, and a seed crystal of group-III element nitride in a crystal growth vessel, pressurizing and heating the crystal growth vessel in an atmosphere of nitrogen-containing gas, and causing the group-III element and nitrogen to react with each other in a melt of the group-III element, the alkali metal and the nitrogen so that a group-III element nitride crystal is grown using the seed crystal as a nucleus. A hydrocarbon having a boiling point higher than the melting point of the alkali metal is added before the pressurization and heating of the crystal growth vessel.

An image forming apparatus is provided with a control section which stores detection results of a toner sensor regarding detection patterns. When forming a plurality of detection patterns on an intermediate transfer belt, the control section determines circumference-directional lengths of the detection patterns formed this time, based on the detection results of the toner sensor regarding the detection patterns formed immediately before. Thereby, the waste toner amount and toner consumption are not only decreased but also the time taken to detect the density of a detection pattern is reduced, while maintaining the detecting accuracy thereof.

When a group III nitride crystal is grown in a pressurized atmosphere of a nitrogen-containing gas from a melt 50 including at least a group III element, nitrogen and an alkali metal or an alkali earth metal, a melt-holding vessel 160 that holds the above-described melt 50 is swung about two axes different in direction from each other such as an x-axis and a Y-axis.
摘要:
A group III element nitride single crystal is grown on a template immersed in a raw material liquid retained in a crucible and containing a group III material and one of an alkali metal and an alkali earth metal. The raw material liquid remaining after the growth of the single crystal is cooled and solidified, and by feeding a hydroxyl group-containing solution into the crucible, the solidified raw material is removed from around the template, and thus the group III element nitride single crystal is taken out from inside the solidified raw material. The template is disposed at a position away from the bottom of the crucible.

A three-dimensional collar shape retaining hanger prevents collars of a plurality of garments from being crushed and is capable of being stacked in a large number. The hanger has a hook portion and a hanger body. Between the hook portion and the hanger body, a connecting plate part which is a central collar supporting portion body is provided to connect the hook portion and the hanger body. A pair of first curved parts which protrudes toward a rear side of the hanger so as to abut on a rear neck portion of a collar is connected to right and left sides of the connecting plate part. To end portions of the first curved parts, a pair of second curved parts is connected at each distal end thereof. Each base end of the second curved parts is connected to the hanger body. A portion between the distal end and the base end of each of the second curved parts protrudes toward the front side of the hanger so as to abut on an inside of a front portion of the collar. By this structure, a curve on a rear neck portion of a collar is supported by the first curved parts while a curve on a front portion of the collar is supported by the second curved parts, thereby retaining a whole curve of the collar. Therefore, when a large number of garments hung on the three-dimensional collar shape retaining hangers are stacked, the collars are not crushed.
