Title: Optical recording and reproducing device
Inventor: AIKO HIDEKI
IPC: G11B7/09
Filed: 1988-12-26
Abstract: PURPOSE:To prevent a drop in the detecting performance of a focus error signal owing to a change in an ambient temperature by providing a reflecting optical element which spatially bisects a converging luminous flux and reflects them in the same direction and a multi-division photodetector with quadripartite light receiving areas. CONSTITUTION:When an objective lens 2 focuses an information recording medium 3, out of reflecting light and transmissive light generated by a convex lens 5a and a detecting element 6, a converting luminous flux passing through a reflecting optical element 7 forms two semi-circular light spots of the same size and the same direction in the quadripartite light receiving areas M of the multi-division photodetector 14. When the dividing line of the quadripartite light receiving areas is position-adjusted so that the incident luminous flux can be received in the uniform light quantity in the four light receiving areas M1 to M4, the quantity of light received in the quadripartite light receiving areas does not change when electrical signals arising in the light receiving areas in diagonal positions are summed, even if the quadripartite light receiving areas change in any directions of the dividing line owing to the change in ambient temperature, etc. Consequently, the output of a differential amplifier obtained by taking the difference between the sums, that is, the focus error signal 15 maintains always the stable detection ability.

Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To easily control the threshold of a semiconductor device by controlling the doner concentration of a carrier supplying layer corresponding to a gate electrode forming area by heat-treating the layer after introducing oxygen to the layer. SOLUTION: A resist mask 108 is formed of a photoresist in a pattern having the opening 107 corresponding to the gate electrode forming area of an enhancement type HEMT. Then oxygen is introduced into InAl 106 and an n-type InAlAs layer 105 through the opening 107 corresponding to the gate electrode forming area by bringing the InAl 106 and layer 105 into contact with ozone by means of an ozone/ashing device. After introducing oxygen, the resist mask 108 is removed by melting and the InAl 106 and layer 105 are heat-treated. By the heat treatment, the InAl 106 and layer 105 are restored from damaged states and, at the same time, the doner concentration of the layer 105 becomes lower. Therefore, the threshold voltage of a semiconductor device can be controlled easily through a simple process.

Abstract: PROBLEM TO BE SOLVED: To efficiently perform an encipherment having high random property by executing a processing including an operation regulated by a function by use of a key data having n-bit length by each of a data having n-bit length. SOLUTION: An inputted data M is divided into host 32 bit M1 and subordinate 32 bit M2 (S201). The modulo addition (x) of work 2 and key data K1-work 2+K1 is performed (S203) a After (x) is circulated and shifted to the left by 2 bit, the modulo addition (x) of the data, (x), and 1 ← Rot 2(x)+x+1 is determined (S204). The same processing is thereafter performed to circulate and shift (x) to the left by 8 bit and then by 16 bit. Then, a function is determined and represented by a composed function. A processing including an operation regulated by the function is executed plural times to the data, whereby the data is generated. Thus, since a 32-bit data is converted or transported by one basic instruction by use of a 32-bit microcomputer, encipherment can be performed at high speed.
