Abstract: PURPOSE:To obtain a photo guiding passage with fluctuated groove width by forming a crystal layer on the surface of a semiconductor substrate having the groove with fluctuated width. CONSTITUTION:A groove 9 with fluctuated width is formed on an n type Ga As crystal substrate 9. On this substrate, an n type Ga Al As 11 and non-doped Ga As 12, for instance, are continuously grown.

Title: Production of electrodeposited mica insulated coil
Inventor: SATOU FUMIHIKO
IPC: H01F5/06
Filed: 1980-03-25
Abstract: PURPOSE:To prevent powdered mica from sliding down when an insulated coil is pulled up from an electrodeposition painting bath by setting the void of an aggregate layer provided on a conductor of an insulated coil at a specified range. CONSTITUTION:In the electrodeposition painting of a conductor employing a water dispersing electrodeposition paint containing powdered mica, electrodeposition of the powdered mica greatly depends on the void of an aggregate layer wound on the conductor. The void of the aggregate layer provided on the conductor of the insulated coil is set at average 30-70%. This keeps the aggregate layer from containing a large amount of water in a water dispersing electrodeposition paint containing the powdered mica when an electrodeposition painting is made. Therefore, after the end of the painting, when the coil is pulled up from a bath for the aggregate layer, the powdered mica is prevented from sliding down as the water contained in the aggregate layer oozes out through the electrodeposited mica powdery layer. In addition, the mica powdery layer electrodeposited can be finished smooth on the surface.

Title: Bonding method for permanent magnet and iron and bonded body
Inventor: IMAI KOJI
IPC: H02K15/03
Filed: 1995-02-28
Abstract: PURPOSE: To achieve the enhancement of bond strength by plating a magnet with molten solder, and then heating it in contact with iron to bond them together by soldering and to form a solder film around the magnet as a corrosion-proof film. CONSTITUTION: A magnet is preheated to approx. 100 deg.C to prevent it from being cracked owing to difference in temperature between its surface and inner part when it is immersed in molten solder. Thereafter flux is applied to the magnet, which is then immersed in a molten solder bath and pulled up approx. 10 seconds later. The thus obtained magnet plated with molten solder is brought into contact with iron coated with flux. The magnet is heated until the solder melts. Subsequently, it is verified that the iron is wet with the solder, and then heating is stopped to cool it. Bonding iron and a permanent magnet by soldering, as mentioned above, provides a bond strength approx. three times that in prior art cases where a magnet is coated with Ni plate.

IPC: G06F15/16
Filed: 1990-02-20
Abstract: PURPOSE:To suppress the increase of overhead by dispatching a leading address to each sub routine while securing an area in the size of a common area in all tasks when starting the task. CONSTITUTION:A compiler 2 is equipped with a parallelizing part 21 and in this part 21, an in-task common area address resolving purpose program generating means 211 is provided. Then, a linker 3 is equipped with an in-task common area address resolving means 31 and a task control means 4 is equipped with an in-task common area allocating means 41. The compiler 2 inputs a source program 1 and generates an object program 6 to be parallelly processed by the parallelizing part 21. Namely, only between the sub routines to be included in the task, the area to be commonly defined/referred is totally allocated when starting each task, and without interposing a dynamic linker, etc., resolution is executed in respect to the reference of the address. Thus, without being conscious of the structure of the task or the number of task, the common area in the task can be dynamically allocated and the overhead can be reduced.
