Patent JP-S58222557-A (JP)
Title: Semiconductor integrated circuit device
Inventor: NISHIMURA TAKASHI
IPC: H01L29/73
Filed: 1982-06-19
Abstract: PURPOSE:To obtain an integrated circuit device having a protection function larger than the conventional one and an input protection circuit which does not give any adverse effect on an input characteristic of the circuit by using an inversion layer as a protection resistance, providing an electrode on an insulating film and connecting an electrode to an input terminal through the MOS structure. CONSTITUTION:When a positive surge is applied to the input terminal 1, a parasitic capacitance is charged through an inverting layer 17 which forms a protection resistance. When a voltage of base terminal 3 exceeds the junction dielectric strength of a diode formed by the p type solicon substrate 10 and n<+> type buried region 11b, a diode breaks down and a current bypasses to a terminal 5 form the input terminal, preventing a potential of base terminal 3 to increase. In case a negative suge is applied to the input terminal 1, a diode becomes conductive and a current is bypassed to the input terminal 1 from the terminal 5 through a protection resistance 2 formed by the inversion layer 17. By since a negative high voltage is also being applied to the electrode 16, the inversion layer 17 becomes narrow and a resistance value of protection resistanle becomes large, while considerably consuming surge energy. Thereby, a remarkably efficient function as the protection circuit can be obtained.

An opening area between the upper lid 10 and holding rod 11 is adjusted to keep the temperature gradient in a part 5mm above a melt 14 to 46-75 deg.C/cm, e.g. 68 deg.C/cm. On the other hand, a seed 12 which is LiTaO3 single crystal and has a pulling up direction of X-axis is attached to the lower end of the holding rod 11, which is then lowered to contact the melt. The seed is subsequently pulled upward while being rotated to grow a crystal, which is then cut off from the melt and cooled. As a result, the aimed single crystal 13 of good quality without causing cracking and bending is obtained.

Title: Medium and method for information recording
Inventor: KOIKE RYUICHI
IPC: G11B7/24094
Filed: 1994-05-20
Abstract: PURPOSE:To deform characters and graphic patterns through a copying by forming pit patterns for characters or graphic patterns having such a size that they are visibly recognized on a recording surface by the difference in optical reflectivity and making the line width to be less than 0.5mm. CONSTITUTION:Visibly recognizable characters and graphic patterns are displayed on the signal surface of a CD-ROM 4 of an original disk. These characters and graphic patterns are either a linear shaped pattern 21 or a character pattern 211. These patterns 21 and 211 are recognized as pattern regions. For a CD-ROM, data are modulated by an EFM system commonly used for a music CD and are recorded on a signal surface using a CLV system or a CAV system. Visualy recognizable characters and graphic patterns are formed by using the difference in optical reflectivity of a pit section and a non-pit section. A CD reproducing device is capable of perfectly reproducing data even though a disk has a scratch having a 1.7mm width. Therefore, the line widths of the patterns 21 and 211 are made less than 1.7mm. Thus, the recognition of an original optical disk among copied disks is easily accomplished by the presence or the absence of the characters and graphic patterns.

Abstract: PURPOSE:To make independently the recording, reproducing, or erasing operation of two disks with interchangeability between them, by providing a means which discriminates the 1st optical disk from the 2nd recordable optical disk. CONSTITUTION:The light beam of a light source 2 is projected upon a reflecting type disk 1 and its reflecting light is received by a photodetector 3. The output signal P of the photodetector 3 is inputted in voltage comparators 6A and 6B as an output voltage VP through a voltage amplifier 4. The voltage VP is compared with the reference voltages V1 and V2 (V1<V2) at the comparators 6A and 6B and, when VP>V1 and VP>V2, signals Q and R are respectively outputted to a deciding circuit 7. When the signals Q and R do not exist, the disk 1 does not exist and, when the signals Q and R exist, the disk 1 is decided as a disk for reproduction only. When the signal Q exists but the signal R does not exist, the disk 1 is decided as a disk to which recording, reproduction, and erasion can be performed. Therefore, the recording, reproduction, and erasion of two disks are made to function independently with interchangeability between them.

Abstract: PURPOSE:To increase a range where displacement amplitude is not vibratory, by varying the viscous resistance of air with displacement, by fitting an annular flat plate on the bobbin inside wall of a bobbin coil. CONSTITUTION:When a signal is inputted to a voice coil 20, an annular flat plate 60 is displaced, so pressure in space 82 varies. The pressure variations pass through the inside and outside of a bobbin 21, and are branched to the 1st path passing through pores of a spider 50, gaps between the flat plate 60 and buffer bodies 71 and 72 and the 2nd path passing through a hole to be released. The viscous resistance of air in the 2nd path varies with the vibratory displacement of the flat plate 60, so the range where the displacement amplitude is not vibratory is increased.
