Title: Optical head
Inventor: KIMURA YASUO
IPC: G11B7/135
Filed: 1988-06-29
Abstract: PURPOSE:To obtain an inexpensive optical head which can be mass-produced by making lattice optical elements into metallic display relief lattices having the specific relation among the wavelength, pitch and lattice depth of a light source, and arranging them so as to form approximately the Bragg angle of the lattice with respect to the incident light to the lattice. CONSTITUTION:A surface relief lattice can control an analystic characteristic by a lattice pitch LAMBDA, a lattice depth (d), an incident angle theta, a lattice form, etc. That is, the optical head has at least a light source 8, an image forming optical system to condense light emitted from the light source 8 on an optical disk 13, a photo detector 14 to receive the reflected light from the optical disk 13, a lambda/4 plate 11 and a lattice optical element 10. Here, the lattice optical element 10 is made into the metallic surface relief lattice 10 having a pitch approximately the same as the wavelength with respect to the wavelength lambdaof the light source, and the lattice depth (d) in the relation of 0.75lambda<d<lambda, and it is arranged to form approximately the Bragg angle of the lattice with respect to the incident light to the lattice. Thus, the manufacture of the polarized beam splitter is facilitated, and an inexpensive analytic type element can be substituted for it.

Title: Optical nonreciprocal element
Inventor: MATSUDA KAORU
IPC: G02F1/09
Filed: 1986-07-11
Abstract: PURPOSE:To obtain a >=60dB isolation ratio by depositing magneto-optical crystal on >=2 different surfaces of a cube made of birefrigerant crystal. CONSTITUTION:A semiconductor laser 7 and an optical nonreciprocal element 11 are so arranged that when the deflecting direction of the projection light 1 of the semiconductor laser 7 rotates by 45 deg. after the laser passes through a 1st magneto-optical crystal 5-1, the light becomes the ordinary light of the birefringent crystal 10; and the projection light 11 which has its polarizing direction rotated by 45 deg. through a 2nd magneto-optical crystal 5-2 passes through an analyzer 4 arranged in parallel to the polarizing direction. The polarizing direction of reflected return light 2 which passes through the analyzer 4 is rotated by the 2nd magneto-optical crystal 5-2 and when the light passes through an optical path different from the projection light 1 and passes through the birefringent crystal 10, the light passes through the 1st magneto-optical crystal 50-1 to have the polarizing direction rotated until the polarizing direction of the projection light, but the light never returns to the semiconductor laser 7. Consequently, the optical isolator which has a >=60dB isolation ratio is easily obtained.

Title: Transferring method for trunk line incoming call in private branch exchange
Inventor: IMAMURA KAZUMASA
IPC: H04M3/46
Filed: 1986-07-11
Abstract: PURPOSE:To make a response to a trunk line incoming call in a key number extension even after the transferring mode is changed over by executing the transferring to a special extension automatically after the key number extension is called for a constant time to the succeeding trunk line incoming call when the number of the non-response call of the trunk line incoming call to the key number extension is a prescribed number or above stored beforehand. CONSTITUTION:For example, the number of the setting of call loss information in a memory circuit 4 is 3 and the response waiting time of a key number extension after the changing-over of a transferring mode is 5 in the number of the call sound. When a key number extension A does not respond to the trunk line incoming call, the call loss information from a trunk line trunk 1 is inputted through signal lines 101 and 102 to the memory circuit 4. When this is continued three times, the changing-over command to the transferring mode is outputted from a signal line 103 to a control circuit 3. After the transferring mode is obtained, when the trunk line incoming call is received to the trunk line trunk 1, the control circuit 3 controls a switch circuit 2 through a signal line 104 and at first, connects the trunk line incoming call to the key number extension A. When the key number extension A responds within five times of the number of the call sound, the control circuit 3 inputs the information through a signal line 105 and releases the transferring mode.

Filed: 1991-07-04
Abstract: PURPOSE:To shorten the charging/discharging time of a data line and to attain a high speed operation of a semiconductor memory circuit by driving an output transistor TR with a driving TR based on a read word line signal. CONSTITUTION:The gates of the FET 1 and 2 serving as the output TRs are connected to the output terminals B and A of each inverter circuit, and a read- only word line XR is provided. The line XR is connected to the gate of an FET 3 serving as a driving TR with the drain connected to the sources of the FET 1 and 2 respectively. At the same time, the voltage VSS is applied to the source of the FET. When the voltage of a high level is applied to the line XR, the FET 3 conducts and both FET 1 and 2 are ready to work. Then the FET 1 and 2 are turned on and off respectively when the potential of the terminal B of the inverter circuit defining an FET 21 as a load is set at a high level with the terminal A set at a low level at the side of an FET 23 respectively. Thus the voltage of a low or high level emerges on a data line Y and therefore the line Y can be charged and discharged at a high speed.
