The organic layer should be bonded to the inorganic glass so well that they are substantially integrated together; for example, an epoxy resin serving as a plastic or setting resin, or an urethane resin is employed in the organic layer.  The surface of the glass layer is coated with a number of layers for the prevention of reflection so as to form an antireflection film, and an antifouling property is further imparted to the surface by antifouling coating and by the formation of a transparent conductive film, with the result that the surface can be shielded also from electromagnetic waves.

Title: Forming method of thick wall material
Inventor: TOYOHARA TSUTOMU
IPC: B21D22/20
Filed: 1984-11-28
Abstract: PURPOSE:To prevent wrinkles from being transferred to a thick wall material from a pack material by using a disk having a spiral-shaped notch, as an upper face pack material contacting to a punch. CONSTITUTION:A thick wall material 1 is covered with an upper face pack material 2, a side face pack material 3 and a lower face pack material 4 in order to prevent a drop of a temperature in the course of working. In this case, only the upper face pack material 2 is formed by a ring material 2' having a spiral-shaped notch, and placed on the upper face of the thick wall material 1. When executing a press forming, as for the upper face pack material 2 contacting to a punch, only the part contacting to the punch is deformed, but no influence is exerted on the ring of its outside. Accordingly, the pack material 2 of the part which does not contact to the punch is not deformed. With regard to the part which contacts to the punch, too, wrinkles are prevented by a rota tion of the ring. According to this method, wrinkles of the punch are prevented, therefore, a transfer of wrinkles to the thick wall material can be prevented.

Abstract: PROBLEM TO BE SOLVED: To accurately stabilize the wavelength conversion output with respect to the aging and ambient temp. change by covering with a cover member a resonator part for resonating a light, emitted from a laser crystal by excitation. SOLUTION: A resonator mirror 14 is disposed at the side opposite to a semiconductor laser 11 for emitting a laser beam 10 as an excitation light. The beam 10 as a fundamental wave is applied to an inversion domain LN crystal 15 for converting it into a second harmonic wave 19 of half the wavelength. An APC photodetector 25 mounted on the end face 22b of a resonator 21 detects a reflected harmonic wave 19. A condenser lens 12 condenses the laser beam 10 to be converted in the crystal 13, the beam 10 passing through an Nd:YAG crystal 13 is reflected and scattered by a holder, etc., which mounts optical members in a holding member 21. The resonator part is covered with a U-shaped sectional cover member 40 with an open underside, to prevent light from leaking, as the reflected lights may be incident on an APC photodetector 25 via a partially reflecting mirror.

Title: Method of attaching die
Inventor: SANEHIKO KAKIHANA
IPC: H01L21/52
Filed: 1988-10-05
Abstract: PURPOSE: To avoid forming voids at mounting a die, by applying a meltable specified material onto the surface of a package, and heating the die and package below the m.p. of the specified material in vacuum. CONSTITUTION: Using a meltable material 4 composed of Au 80% and Sn 20%, a die 2 is positioned on a package 1, and it is evacuated and heated to rise the temp. below the m.pt. of the material 4, resulting in the release of a trapped gas from the material 4, and the gas is removed by the applied vacuum. Then, the temp. is risen to melt the material 4, thereby forming good contact with the surface of a backside metallization 9. Thus, it is possible to mount the die 2 on the package 1 without causing voids.

Abstract: PURPOSE:To enhance not only sensitivity but also the electronic countermeasure capacity against radio wave jamming, by using a switching signal for mixing subjected to two-phase modulation based on a zero phase and a pi-phase to apply frequency conversion to the reflected wave from a target. CONSTITUTION:A receiving signal obtained by receiving the reflected signal from a target is branched to use no only a signal 18 not subjected to phase modulation in a first mixer 15 as a switching signal but also a signal lowered to intermediate frequency as the reference signal 23 of a synchronous detector 24. The other branched receiving signal is used in a second mixer 16 as a switching signal 20 for mixing subjected to two-phase modulation of a zero radian and a pi-radian by a two-phase modulator 19 and a signal 29 converted to intermediate frequency is subjected to synchronous detection on the basis of the reference signal 23 by the synchronous detector 24 to obtain output 47. Using this output 47 and the signal synchronous to a transmission signal, the switching signal 20 subjected to two-phase modulation by the two-phase modulator 19 is controlled so that a phase is changed over by the pi-radian at the almost center position of the receiving signal and the detection of the position of the receiving signal is enabled to constitute a negative feedback loop for the synchronism with the receiving signal.

IPC: G06K7/10
Filed: 1992-09-18
Abstract: PURPOSE:To enhance a read rate by decoding efficiently bar-code data. CONSTITUTION:For instance, an NW 7 searches a bar of the maximum width and a space of the maximum width in six pieces of bars/spaces except a first one piece of bar in start/stop characters. Subsequently, a reference value is derived from the maximum bar width, and the bar is regarded as a wide bar, and a narrow bar, when the bar width exceeds the reference value, and when it is smaller than the reference value, respectively. Also, a reference value is derived from the maximum space width, and the space is regarded as a wide space, and a narrow space, when the space width exceeds the reference value, and when it is smaller than the reference value, respectively. Next, by allocating '0' to a narrow element, and allocating '1' to a wide element, a binary number of 6 bits is generated, and by comparing its binary number with a start and stop character table, a character value is derived.
