Title: Optical recording medium and its recording and reproducing method
Inventor: SHINOHARA SHIGEYUKI
IPC: G11B7/24
Filed: 1990-09-13
Abstract: PURPOSE:To prevent the occurrence of an erroneous signal due to a flaw on the surface of a medium with a simple constitution by successively laminating an optical recording layer which can be punched with irradiaion of recording light, a polarization plane rotating layer, and a light reflecting layer on a transparent substrate. CONSTITUTION:When an optical recording layer 3 of an optical recording medium 1 is irradiated with recording light 21 stronger than reproducing light, this layer 3 is punched in the irradiated part to form a hole part 31, and a signal is recorded. When this hole part 31 is irradiated with reproducing light 21, this light 21 is transmitted through the hole part 31 and a polarization plane rotating layer 4 and is reflected by a light reflecting layer 5. Since reflected light has the plane of polarization rotated while being transmitted back and forth through the polarization plane rotating layer 4, the light 22 has a polarized light component which has the plane of polarization perpendicular to the surface of paper, and this component is reflected by a polarizing beam splitter 13 and is detected as signal light 23 by a photodetector 14 and the signal is reproduced. Thus, the occurrence of an erroneous signal due to a flaw on the surface of the optical recording medium 1 is prevented, and information is recorded and reproduced with a high reliability.

Title: Cooling device for electronic circuit
Inventor: SANO TOSHIFUMI
IPC: H01L23/46
Filed: 1987-09-29
Abstract: PURPOSE:To allow a certain, optimal control of cooling air with a simple constitution by controlling with upper and lower bars on a link mechanism the opening and closing operation of vanes of a vane mechanism arranged between package guides. CONSTITUTION:When an electronic circuit package 1 is not inserted into a package guide, vanes 6 of a vane mechanism 3 are closed with a lower bar 8 being pulled by a spring 16, whereby the flow of cooling air is blocked. Upon insertion of the package 1, a guide pin 5 thereof presses a connecting part 15 of an upper bar 7 to rotate the vanes 6 to an opening position, whereby cooling air is introduced to the package 1. At this point, cooling air flow volume is adjusted by rotating angle of the vanes 6 being changed in function of the mounting position of the pin 5. According to the constitution, cooling air can be controlled optimally without fail with a simple constitution which requires no dummy module or cover plate.

Title: Synchronism holder
Inventor: HIRAMATSU KATSUHIKO
IPC: H04L7/08
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a synchronism holder with which frame timing can be held even in case of line disconnection for a long time by estimating the deviation of timing based on the differential average value of frame timing even when a unique word(UW) is not received. SOLUTION: The reception time of a known symbol pattern is found by a reference timer 105 and a UW pattern detection circuit 102 and from the difference from the time when the known symbol pattern is detected the last time, a differential circuit 111 detects the difference of timing between a transmitter and a receiver per unit time. The average value of this timing difference is calculated by an average value calculation circuit 113 and further, the average value is integrated at every unit time by a timing difference integration circuit 115 so that the difference of timing between the transmitter and the receiver at a current time point is detected. Based on this integrated value of timing difference, the time for one frame of the receiver is increased/decreased just once and the timing of the receiver is held for the transmitter.  Since the average value is integrated, the timing difference can be detected even when the UW pattern is not detected for a long time.

Title: Instruction processor
Inventor: HARA TETSUYA
IPC: G06F9/38
Filed: 1994-10-12
Abstract: PURPOSE: To provide an instruction processor which has a branch destination buffer which can easily be structured, has high branch prediction precision, and generates no cycle penalty. CONSTITUTION: A branch execution unit 30 processes operand data supplied from an instruction decoder together with branch instruction information read out from the branch destination buffer 20, predicts and executes branching, and generates and supplies a branch probability flag generated in relation with the branch instruction to a BTB registration/update determining mechanism 32. When an unregistered branch instruction is registered in the branch destination buffer, it is registered or not registered by the BTB registration/update determining mechanism 32 according to the value of the branch probability flag. Consequently, the registration of a branch instruction with a low branch probability in the branch destination buffer can be suppressed and the branch prediction precision is prevented from decreasing. The branching is predicted by using only effective bits V.
