Title: Polarized beam splitter
Inventor: MONMA SATORU
IPC: G02B5/30
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To stabilize the characteristic of an optical pickup, etc., by making a ratio of transmittance to reflectance approximately constant without being influenced by variations in humidity of the environment even if a polarizing light separation film is manufacture by means of an inexpensive vapor deposition method by which air gaps are formed in a film such as an EB(Electron Beam) vapor deposition method. SOLUTION: A form of a spectrum characteristic is arranged by a 1st layer film 9-1, a 2nd layer film 9-2,..., a 5th layer film 9-5 composed of a polarizing light separation film 4 and a wavelength dependency is adjusted so that the wavelength dependency within the wavelengths range to be used is not made to a flat form but a little right downwards (transmittance becomes lower on the side of longer wavelengths). Further, as a 4th layer film 9-4 to N-th layer film 9-N, a high refractive index medium (H) film and a low refractive index medium (L) film are alternately laminated, an optical thickness ratio of both films is made to '2:1' and vertical variations in the spectrum characteristic (transmittance in the vertical direction) are reduced while lateral variations in the spectrum characteristic (wavelength shift direction) are sacrificed.

Title: Glass for bonding ceramic
Inventor: WATANABE KAZUNARI
IPC: H01L23/15
Filed: 1989-09-19
Abstract: PURPOSE:To obtain a bonding glass suitable for the bonding of glass ceramic and aluminum nitride by using a glass frit having a restricted composition and containing specific amounts of especially PbO, B2O3, SiO2 and Al2O3. CONSTITUTION:The objective glass is composed of 70-100wt.% of glass frit and 0-30wt.% of a filler and the glass frit is composed of 20-50wt.% of PbO, 1-15wt.% of B2O3, 35-55wt.% of SiO2, 3-15wt.% of Al2O3, 0-15wt.% of MgO+CaO + BaO+SrO, 0-5wt.% of ZnO, 0-5wt.% of TiO2, 0-5wt.% of ZrO2 and 0-5wt.% of Li2O+Na2O+K2O. Since the thermal expansion coefficient of the glass layer of the present bonding glass at the bonding part is close to that of glass ceramic substrate or AlN substrate compared with conventional soldering material such as a silver solder, the reliability of the bonding part can be improved. Furthermore, the number of steps can be decreased because it is not necessary to form a metallized layer on the bonding part of the glass ceramic substrate or the AlN substrate in contrast to soldering process.

Title: Image forming device
Inventor: TOYOHARA YUICHIRO
IPC: G05D23/19
Filed: 1994-09-09
Abstract: PURPOSE: To provide an image forming device capable of obtaining excellent fixability always regardless of a factor such as room temperature. CONSTITUTION: The energization of a heater is started (S1), the counting of a timer is started (S2) and then times tc and ta required for the heater to reach temperatures of 120 deg.C and 150 deg.C respectively are counted (S4-S7) while a target temp. is set at 200 deg.C (S3). It is judged whether or not the time ta is <10 seconds (S8) and when the time ta is <10 seconds, pre-multi rotation is immediately started to complete the fixing (S9). When the time ta is >=30 seconds (S10), the device enters a defective mode of requiring the longest warm-up time (S11). The time tb required for the heater to raise a temp. from 120 deg.C to 150 deg.C is calculated by using the times ta and tc (S12) and a temperature rise gradient index is obtained through the use of a coefficient of correction defined as 1.5 to calculate an environment index (S13).  When the environment index is >=17, 12 to 17 and <=12, it is decided that the condition of the device is in a high temperature mode (S14-S15), a middle temperature mode (S16-S17) and a low temperature mode (S16-S18), respectively and a warm-up time is made longer as the environment index is smaller.

A paste form mixture prepared by using paste-form material as matrix and filling it with particulates 3 consisting of diamond or CBN is applied to the inside of each pocket 5 produced in the primary baking process. The object obtained is subjected to a secondary baking process at a specified temp.  Accordingly the abrasive grains 1 are retained by a binder 4 reinforced by the particulates 3, and precluded from premature fallout.
