Title: Optical disk device
Inventor: TAKEUCHI RYOJI
IPC: G11B7/00
Filed: 1989-09-29
Abstract: PURPOSE:To prevent double writing without fail by comparing the reflected light of a pulse-shaped recording light beam from an optical disk with a prescribed threshold level and stopping a recording operation when the counted value of a pulse more than the prescribed level is more than a prescribed value. CONSTITUTION:The double write is detected by utilizing a property that as for the intensity of the reflected light of the pulse-shaped recording light beam a case the beam is reflected from a recorded area is different from a case that it is reflected from an unrecorded area. Namely, the pulse-shaped recording light beam is radiated from a light output means 5 and the reflected light is compared with the prescribed level. Then, the reflected more than the prescribed level is detected by a detecting means 30 and the number of the pulses more than the prescribed level is counted by a counting means 31. When the counted value is more than the prescribed value, it is judged that the area is the recorded area, and the recording operation is stopped. Thus, an optical disk device, which can prevent the double writing without fail, can be obtained.

Title: Method for performing data operation in register with simplified-instruction-set processor
Inventor: RICHIYAADO ERU SHIITOSU
IPC: G06F9/38
Filed: 1991-06-28
Abstract: PURPOSE: To convert data structure and a code which are already generated for an existent CISC type processor into those that a high-performance processor use while making good use of all the advantages of RISC type processor architecture. CONSTITUTION: The RISC(reduced instruction set) type high-performance CPU 10 uses standard fixed instructions 16-19. Atomic byte writing can be performed with load lock/store condition instructions. Many short branches can be excluded with conditional move instructions. With the conditional move instructions, registers are tested and when the conditions are met, a 2nd register is moved to a 3rd register, this function replaces the short branches, and a sequence of the instruction flow is maintained. A target of a branch is predicted and a new instruction is fetched to increase the execution speed. Unused bits of a standard-size instruction are used to give clues to a jump instruction and a predicted target for the jump instruction to a subroutine.

Abstract: PURPOSE:To detect highly precise rotation extending over a wide temperature range by outputting a rotation detection signal having the fixed pulse width without being influenced by a change of the outside air temperature. CONSTITUTION:Threshold setting circuits 10 and 11 are constituted by connecting resistances R1 and R2, and R3 and R4 in series and the prescribed set voltages VT10 and VT11 are outputted between resistances R3 and R4 with the circuit 10 and between resistances R and R with the circuit 11 respectively. Here, the set voltage VT10 at the time of the normal temperature is made VT10<Vout4DC with respect to the D.C. voltage level Vout4DC of a detection part 4 at the circuit 10 side and the set voltage VT11 at the time of the normal temperature is made VT11>Vout5DC with respect to the D.C. voltage level Vout5DC of a detection part 5 at the circuit 11 side. Accordingly, the output voltage Vout4(5) is made low (high) at the time of the high temperature with respect to at the time of the low temperature or at the time of the high temperature at the detection part 4(5) side. In this way, since there is the relation of the above-mentioned formula at the time of the normal temperature between the detection part 4(5) and the circuit 10(11), a variation of the pulse width by the output voltage Vout4(5) from a comparison circuit 14(15) based on the voltage VT10(VT11) can be reduced.

Abstract: PROBLEM TO BE SOLVED: To obtain a distance-measuring apparatus in which the damage such as the crack or the like of a bonding face and the degradation of optical characteristic due to temperature change are suppressed by making one of achromatic image-formation lenses possible to be relatively contact-displaced to the other. SOLUTION: The ends on one side of plano-concave lenses 20R, 20L are fixed with a lens tightening screw 26 so as to be used as fixed ends, and ends on the other side are pressed from above by a leaf-spring lens holder 29 so as to be used as expansion and contraction free ends having the degree of a small freedom. Thereby, since the lenses 20R, 20L can be expanded freely at a high temperature, the generation of a thermal stress can be suppressed, and the degradation of various optical characteristics due to the influence of heat can be reduced. In addition, ends on one side of plan-convex lenses 22R, 22L on the upper side are not fixed with the screw 26 so as to be used as free ends. Since the ends on the other side are pressed from above by the lens holder 29, they are used as expansion and contraction free ends having the degree of freedom to a certain extent.  As a result, the lenses 22R, 22L can be contact- displaced onto the lenses 20R, 20L relatively.
