Title: Semiconductor pressure sensor
Inventor: KOBAYASHI EIJI
IPC: G01L9/00
Filed: 1990-10-24
Abstract: PURPOSE:To reduce the nonuniformity in an electrical characteristic and to improve accuracy by forming a plurality of projections on the bonding surface of a semiconductor pressure element which is fixed on a package base by a bonding agent. CONSTITUTION:A plurality of projections 3a of a height (h) are provided on the bonding surface of the bottom of a fixing part 3 of a semiconductor pressure element 1, on which the element is bonded to a package base 4. Thereby a uniform gap of the height (h) is formed between the fixing part 3 and the base 4, and the element 1 is fixed to the base 4 by filling up a bonding agent 5 in this gap. On the occasion, the thickness of the bonding agent 5 is kept to be (h) by the projections 3a and the thickness can be selected by selecting the height (h) of the projections 3a. According to this constitution, the thickness being sufficient is obtained, and even when the element 1 is left as it is at a high temperature, an internal stress is absorbed by the elasticity of the bonding agent 5, whereby deformation of the element 1 can be prevented. By the projections 3a in a plurality, besides, a uniform bonding layer is obtained in the whole periphery between the fixing part 3 and the base 4.

Title: Automatic port switching device
Inventor: NEZU KAZUNORI
IPC: G06F3/12
Filed: 1989-11-08
Abstract: PURPOSE:To simplify a circuit by selecting the ports of high-order devices in the order of priority levels of signals outputted from high-order devices when plural high-order devices use a common data input/output device. CONSTITUTION:Drivers/receivers 11 to 13 and 14 to 16 for data and control signal provided on every high-order device transmit/receive data and control signals between plural high-order devices 1 and 2 and the common data input/ output device. An OR circuit 19 operates the OR signal between input prime signals outputted from high-order devices 1 and 2 and gives it as an initial signal to the common data input/output device. When plural input prime signals are simultaneously present thereon, a port selecting circuit 17 validates the operation of drivers/receivers for data and control signal for one high-order device which outputs the input prime signal having the highest priority level in accordance with the precedence. Thus, a CPU, a program ROM, a transmission/reception timing circuit are eliminated to simplify the circuit.

Title: Preparation of fiber board
Inventor: MORITA SEIJI
IPC: B29K105/06
Filed: 1985-12-23
Abstract: PURPOSE:To attempt to have weight saving and to improve the bending strength by spreading a foamable phenol resin at least on one side of a mat-shaped fibrous material and thereafter by heating and press-molding it. CONSTITUTION:A specified amt. of foamable phenol resin is uniformly spread on one or both sides of a met-shaped fibrous material formed in a specified thickness in advance and it is thereafter heated and press-molded to prepare a fiber board. The foamable phenol resin melts by heating, forms (expands) to 5-50 times of its original vol. and is cured. The molten foamable phenol resin penetrates into the mat-shaped fibrous material by this foaming force and completely fills up the gaps and is thereafter cured. The bonding forces between fibers are thereby strengthened and the bending strength of 50-60fkg/ cm<2> can be obtained. The density of the phenol resin foam filling up the gaps is 0.02-0.2g/cm<3>, which is light wt. and the density of the fiber board thereby becomes 0.1-0.7g/cm<3>.

Filed: 1992-10-28
Abstract: PURPOSE:To change the size of an image-formed character and to change an image-formation position with a single character light emitting device by providing a movable mirror for changing the image-formation position and the size of the image of character light emitted from the character light emitting device. CONSTITUTION:The character light emitting device 1 emits light in a Y axis direction in the case of photographing in a standard size, the light from the light emitting device 1 is reflected by a mirror 2 so as to change an optical path to a -X axis direction. The direction of the optical path of the light is changed to a -Z axis direction by the mirror 3 in the same way, and the image is formed on a point (a) on a film surface 5. In the case of photographing with a panoramic image plane, the mirror 2 retreats to a point (A), and the light reflected from the character light emitting device 1 is reflected by the mirror 4 and is image-formed on a point (b) on the film surface 5. Since the optical path length of the character light in the case of the photographing in the standard size is different from that in the case of photographing in the panoramic size, focusing d position is deviated; therefore, a lens 6 moves to correct it. Furthermore, a mirror lens in which the curvature of the mirrors 2 and 4 are changed can be used.
