Title: Lambda/4 phase shift diffraction grating
Inventor: TADA HITOSHI
IPC: H01S5/00
Filed: 1991-07-12
Abstract: PURPOSE:To obtain the lambda/4 phase shift diffraction grating without shifting the period of the diffraction grating by half wavelength each with a ordinary two luminous fluxs interference exposing by forming the diffraction grating of two semiconductors varying in refractive index and embedding the diffraction grating with a 3rd semiconductor having the intermediate refractive index of these semiconductors. CONSTITUTION:The 1st semiconductors 12 consisting of AlyGa(0.47-y)In0.53As and having the 1st refractive index and the 2nd semiconductors 13 consisting of InP and having the 2nd refractive index are formed on a semiconductor substrate 1 consisting of InP in such a manner that these semiconductors are adjacent to each other. The semiconductors 12, 13 are embedded with the 3rd semiconductor 14 having the intermediate refractive index of the refractive indices of the semiconductors 12 and the semiconductors 13 varying in the compsn. ratio. The refractive index of the diffraction grating is, therefore, changed in the in-phase regions 5a and the anti-phase regions 5b and the light advancing into the diffraction grating receives reflection toward the side of the higher refractive index by the change in the refractive index. The reflection of the light deviates by the half wavelength when the light advances from the in-phase region 5a to the anti-phase region 5b.

Title: Distributor used for ignition of internal combustion engine
Inventor: KASUFUCHI FUMIAKI
IPC: F02P7/02
Filed: 1981-10-30
Abstract: PURPOSE:To incorporate an ignition coil securely in a required place, by fixing the ignition coil clamped in a casing securely in a molding tool, and molding  a distributor cap integrally with the ignition coil. CONSTITUTION:A distributor cap 5 is molded in a unitary manner by pouring an insulating material into a tool for molding the cap 5 having an ignition coil incorporating case 15 fixed thereto. An ignition coil 4 is fixed securely in the cap molding tool by the intermediary of the case 15 and buried in the cap 5. Thus, a distributor cap 5 having an ignition coil 4 disposed securely at a required position can be obtained. After molding, holes 27, 28 are formed to extend through the wall of the cap 5, and a rubber hose or the like is attached to the top 29 of the hole 29, whereby the holes can be used as vent holes capable of preventing intrusion of water from the outside, and at the same time, ozone generated by the sparks can be removed through the holes. Thus, since the ignition coil is covered with a molding resin completely in a hermetical manner, it has a high resistance to water and leakage of voltage can be eliminated.

Title: Peak value detection circuit
Inventor: ERA YOSHIKAZU
IPC: G01R19/04
Filed: 1991-06-19
Abstract: PURPOSE:To lower errors which is generated by a temperature change in a peak value detection circuit to be used in an AGC amplification circuit or the like. CONSTITUTION:A bias current from a current source 11 with respect to diode couples 9 and 10 for generating a reference voltage is equivalent to the value of addition of current only corresponding to current charging a capacitor 5 flowing through the diode couples 3 and 4 to a bias current from a current source 6 with respect to diode couples 3 and 4 for detecting a peak value, which enable the coinciding of temperature coefficients between both the diode couples. A difference is calculated with an adder 7 between a voltage across both ends of the diode couples 9 and 10 and a voltage across both ends of the diodes 3 and 4 to output. This enables the obtaining of a peak value detection output of a highly accurate input signal free from any temperature change.
