Title: Optical amplifier
Inventor: KOSAKA JUNYA
IPC: H01S3/06
Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To make an optical amplifier simple and compact by connecting an active lens, in which a rare earth element is added, to an optical fiber as a communications circuit, and providing an excitation light source for exciting the active lens. SOLUTION: The excited light from an excitation light source 3 is applied into an active lens 2, in which a rare earth element (for example, erbium) is added. The distance between the emitting end of the excitation light source 3 and the active lens 2 is set at, e.g. 0.5mm so that the excited light is applied on the entire active lens 2 as much as possible. The signal light input from an optical fiber 1 as a communications circuit is amplified in the active lens 2 and emitted from the other end of the active lens 2. The emitted light is condensed and inputted into the optical fiber 1 again.  When a spherical lens is used as the active lens 2 at this timer the excited light can be guided into the active lens 2 simply from the different direction with respect to the advancing direction of the signal light, the position deviation of the excitation light source 3 can be allowed to some extent and optical loss between the optical fiber 1 and the active lens 2 can be reduced.

Title: Manufacture of acoustic diaphragm
Inventor: WATANABE KAZUHIRO
IPC: H04R31/00
Filed: 1990-07-27
Abstract: PURPOSE:To easily obtain an excellent acoustic characteristic by applying heat treatment to a high polymer film compression molded to a dome or a cone shape at a specific temperature under an inert gas environment so as to attain graphite processing when a polyamide acid is converted into a polyamide by thermal polycondens. CONSTITUTION:The heat treatment processed under an inert gas environment is implemented so as to reach 2000 deg.C or over so that graphite processing is sufficiently progressed and a usual pressure of 0.1-200kg/cm<2> is exerted after the temperature reaches 2000 deg.C. Thus, since the compression molding to obtain a dome or a cone shape is implemented in the drawing enable state in the imide processing progressing stage in which imide processing is finished, a proper shape such as a done or cone is easily obtained. Thus, a graphite-made diaphragm with excellent acoustic characteristic is obtained.

IPC: H01L23/12
Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device, with a built-in multilayer board, whose reliability is high, whose yield is high and which is low-cost. SOLUTION: A depressing operation is not executed to a lead frame 6 which is connected to a multilayer wiring board 1 which is built in a semiconductor device 8 with a built-in board. Instead of executing a depressing operation to the lead frame 6, the thickness in the layer direction of only parts to which the lead frame 6 is connected at the multilayer wiring board 1 is controlled. Thereby, it is possible to obtain a structure in which the central axis of the thickness in the layer direction of the multilayer wiring board 1 including the thickness of IC chip 2 and an SMD 9 mounted on the multilayer wiring board 1 built in the semiconductor device 8 with the built-in board agrees with the central axis of the thickness in the layer direction of the semiconductor device 8 with the built-in multilayer board. Since the depressing operation is not executed to the lead frame 6 in any case, the lead frame 6 and a wiring pattern 3 on the multilayer wiring board 1 can be connected in a state that both are always horizontal.
