Title: Head lamp device for automobile
Inventor: CHOJI MASATAKA
IPC: F21V15/01
Filed: 1988-12-15
Abstract: PURPOSE:To improve strength of a lens cover without increasing the thickness of the lens cover itself or without providing a rib by providing a curvature with a rising part that begins at the cover surface solidly on a part correspondent to an effective light distribution part by a projection lens on the surface of the lens cover. CONSTITUTION:Head lamp units 4, 5 being built in a car body 2, an opening 8 that is opened on the car body 2 is covered with a lens cover 10. A thin aero-type head lamp device is thus offered, and, since curvatures 12, 13 are formed on the lens cover 10 through a rising part 14, which functions as a rib, strength of the lens cover 10 itself is increased. The lens cover 10 can thus be prevented from damage without thickening the plate thickness or without providing a rib on the back side.

Title: Unsealing method of ic package
Inventor: INAGAKI MASAFUMI
IPC: H01L21/66
Filed: 1990-11-20
Abstract: PURPOSE:To enable the title IC package to be unsealed without breaking down the other parts excluding the specific part by a method when a metallic member in different thermal expansion coefficient from that of a ceramic is bonded onto the cap of ceramic package and then the sealed part is broken down by giving thermal shocks. CONSTITUTION:A metallic sheet 6 in different thermal expansion coefficient is stuck on the cap 1 of a ceramic package using a bonding agent 5. Next, the thermal shock is given to the whole package within proper temperature range. Thus, a stress is imposed on the ceramic package due to the difference in the thermal expansion coefficient giving a crack in the most fragile glass sealed part. Furthermore, when the thermal shocks are repeatedly given, the cracked area is spread finally to separate the cap 1 from the ceramic main body 4. Through these procedures, a specimen of the IC package can be unsealed without impressing excessive stress thereon thereby avoiding the mixing of fragments in the IC package or the breakdown of a chip 8.

Title: Electromagnetic induction heating type roaster
Inventor: HATTORI YOSHITAKA
IPC: A47J37/06
Filed: 1999-09-29
Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic induction heating type roaster equipped with a heat insulating body having durability, wherein the linear expansion coefficient is small, and the thermal deformation is extremely small. SOLUTION: In a heat insulating body made of ceramic, which is used for an electrmagnetic induction heating type roaster, cracks or splits are generated due to a rapid temperature increase at the time of a starting, and also, due to a partial rapid cooling by the juice content of a food material, which drops on the heat insulating body during a roast-cooking, and the durability becomes low. In order to eliminate such a problem, lithium (Li2O) is added to the composition of a heat insulating body 6 made of an alumina/silica based ceramic, and the coefficient of linear expansion is made smaller for this electromagnetic induction heating type roaster.

Filed: 1988-12-14
Abstract: PURPOSE:To transmit/receive plural commands and status in parallel by allowing a master unit to transfer information to a slave unit while checking a response to the information being transmitted from itself. CONSTITUTION:When a transfer control circuit 1 generates a request (BREQ), a control circuit 3 generates a permission (BGRM), the master unit 100-1 receives the BGRM and a control circuit 1 sends the information in a register 5 to a data bus 200-1 in the order of a command, an address and data and simultaneously generates a bus start signal (BSTT). The slave unit 100-2 inputs the information as the one sent to itself. At the time of receiving the BSTT on the bus 200-2, a monitor circuit 10 generates a permission BGRS to the slave unit 100-2. The unit 100-2 sends a response to a response line 200-3 every 1tau and the unit 100-1 transfers information while checking the response and finally generates a transfer end BCP7. A bus arbiter successively drops the permission BGRM and BCRS.

Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To compensate various aberrations needed in terms of performance with good balance and obtain an inexpensive lens by specifying the refractive indexes of at least two lenses including a 1st lens. SOLUTION: The lens composed of a 1st positive meniscus lens which is convex to an object side, a 2nd biconcave lens, a 3rd biconvex lens, and a stop in order from the object side, the refractive indexes of the two lenses including the 1st lens are set to <=1.6, and conditions of 0.20<f3 /f<0.45 and 0.24<r5 /f<0.45 are satisfied. Here, f3 is the focal length of the 3rd lens, r5 is the radius of curvature of the object-side surface of the 3rd lens, and (f) is the focal length of the whole system. In this case, a material which is low in refractive index is used for the 1st lens and further a material which has a low refractive index is used for the 2nd or 3rd lens as well.  Thus, the radius of curvature of the 3rd lens on the object side and its refracting power are made adequate to compensate off-axis curvature of field and a spherical aberration with good balance, thereby securing stable performance from the center to off the axis.
