Title: Exposure device
Inventor: ITO FUMIO
IPC: G11B7/26
Filed: 1989-02-03
Abstract: PURPOSE:To eliminate an influence of reflected light upon a focus servo system and to stabilize the focus servo to an objective lens by forming plural projecting parts having acute angles smaller than 60 deg. on the surface part of a turntable and attenuating the laser beam, with which the surface is irradiated, with plural times of reflection. CONSTITUTION:The side face part of each projecting part 17a on the surface part of a turntable 17 is irradiated at an incidence angle theta1 with the laser beam from the focus servo system to the surface of the turntable 17, and this beam is reflected at the reflection angle theta1. Since a vertical angle alpha of each projecting part 17a is set to an acute angle smaller than 60 deg., the reflected light from the side face part goes along an optical path which is not extremely deviated from the optical path for irradiation with respect to angle. The side face part of the adjacent projecting part 17a is irradiated at an incidence angle theta2 with the reflected light and it is reflected at a reflection angle theta2, and the angle of incidence and that of reflection are gradually increased but the light is attenuated according as these incidence and reflection are repeated. Consequently, an influence upon the laser oscillating state is completely eliminated.

Title: Input circuit with hysteresis
Inventor: SASAKI MASAYUKI
IPC: G01R19/165
Filed: 1986-02-07
Abstract: PURPOSE:To easily generate hysteresis and to reduce variation in hysteresis voltage by switching the current value of a current conducting at the forward voltage generation part in a P-N junction which generates the comparison reference voltage of a comparator. CONSTITUTION:When the input potential at a terminal 14 is lower than the reference potential, a transistor (TR) Q3 is off, a TR Q4 is on, and a TR Q11 is off, so a TR Q10 is off and the constant current 'I+7I' (7I: through a TR Q9) of the mirror circuit of TRs Q5 and Q6 is conducted to TRs Q7 and Q8, so that the current forward voltage gives the reference voltage. When the input potential is lower than the reference potential, on the other hand, the TR Q3 is on, the TR Q4 is off, and the TRs Q11 and Q10 are both on, so only a current I is conducted to the TRs Q7 and Q8. Therefore, the difference between the P-N junction forward voltages when the currents I and 8I are conducted to the TRs Q7 and Q8 gives a hysteresis voltage.

Title: Metallic mold for casting and production thereof
Inventor: TOFUN MASAHIDE
IPC: B22F3/14
Filed: 1995-02-14
Abstract: PURPOSE: To obtain a casting metallic mold having good gas exhaust, heat retaining property and molten metal running by forming the metallic mold for casting with metallic sintered body and arranging many slits communicated with the outer air from a cavity forming surface. CONSTITUTION: The metal mixing powder for sintering is formed as plate-state on the thin plate of copper or copper alloy. The formed body is preliminarily sintered at below the m.p. of the thin plate. The preliminary sintered formed bodies are laminated in many layers and press-formed. The sintering treatment is executed to the laminated formed body at above the m.p. of the thin plate and the thin plate is melted to form the slits 3. The thickness of the thin plate is selected so that the width of the slit 3 becomes 0.1-1mm. The cavity 5 is formed in the sintering formed body to make the metallic mold 4. By this method, since there are many slits 3 communicated with the outer air from the cavity 5 formed surface, the gas exhaust is good.  Further, since the slits 3 exist, the contacting area between the molten metal and the metallic mold 4 is reduced and the drop of molten metal temp. during flowing is reduced and the molten metal running is good and the thin casting can be produced.

Title: Still picture transmission device
Inventor: OOGAWARA TOMIO
IPC: H04N7/12
Filed: 1978-03-06
Abstract: PURPOSE:To obtain a picture image containing plural screens in one picture frame by giving the reduction memory to plural picture signals and then reading out and transmitting the picture signals in sequence. CONSTITUTION:The TV signals picked up through cameras 1-4 are written into memory 11. The 1-field signal sent from camera 1 is compressed down to 1/4 area frame and then written into the 1/4 area of memory 11 equivalent to one picture frame. Then switch 9 is switched to camera 2 to carry out the writing in the same way. Thus, the writing is given to memory 11 with sequential switching of the cameras. The data written into memory 11 is read out in a low speed and then converted into the narrow-band signal to be delivered. The transmitted signals are supplied to the receiver to be then written into memory 16 in sequence. The data in memory 16 is read out in the TV signal rate to be supplied to TV monitor 9. Thus, the picture image can be obtained at four areas of one picture frame at one time.

Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To provide an interface circuit which is free from restrictions on clock cycles used for two circuits operating asynchronously and can perform high speed data transmission with a simple circuit constitution. SOLUTION: A 1st circuit 10 which operates synchronously with a 1st clock signal 100 outputs a write enable signal 103 according to a write request signal 100. When the write enable signal 103 is effective, a write signal 104 and a write address 105 are generated and write data 102 are written in a buffer 12. Further, read data 106 are read out of the buffer 12 according to a read signal 108 and a read address 109. An address comparing circuit 19 compares the write address 105 and read address 109 with each other to detect the number of data stored in the buffer 12 and then compares it with a set value to generate a write acknowledgement signal 113 and a read acknowledgement signal 112. In this case, the comparing operation is always carried out, but timing wherein both the addresses have no change is specified to obtain a stable comparison result.

Abstract: PROBLEM TO BE SOLVED: To obtain a new aromatic carbonate compound having excellent water resistance and chemical resistance at an ambient temperature, capable of reacting at a high speed at a low temperature upon heating and useful as a heat-sensitive agent or a thermal recording material. SOLUTION: A compound of the formula (R is phenyl, 2-chlorophenyl, 2,4- dichlorophenyl or 4-nitrophenyl), e.g. 4-phenyloxycarbamoyldiphenylamine. A compound of the formula is produced by reacting 4-aminodiphenylamine with phenyl chloroformate in a solvent (e.g. toluene) at 10-90 deg.C. The compound of the formula quickly dissociates the part of urethane bonding by heating and forms an isocyanate compound and a phenol. On the other hand, the highly reactive isocyanate group is blocked at the ambient temperature, and thus the compound exhibits excellent durability against a solvent, water and a chemical.  A thermal recording material produced by forming a thermal recording layer containing a compound of the formula and an imino compound on a supporting body is excellent in coloring property, resistant to the discoloration of printed part caused by a chemical such as a plasticizer, having little trouble of fogging of a background and having an excellent image preservation.
