Title: Retiming circuit
Inventor: USUKI SHIGERU
IPC: H04L7/02
Filed: 1987-04-17
Abstract: PURPOSE:To suppress jitter of the internal timing lower by using a comparator circuit comparing several steps of reference values and a delay quantity subject to bit conversion and varying the weight so as to control the count when the same state is consecutive as the comparison. CONSTITUTION:The comparison circuit 10 compares several reference values A set internally and the converted bit number so as to detect which reference values A the bit number resides and the corresponding signal is outputted to a weighting circuit 11. On the other hand, when the signal from the comparator circuit 10 is consecutive with the same state, the counter circuit 12 counts the signal and supplies an output to the comparator circuit 13. The comparator circuit 13 compares the reference value B set in the inside with the count from the counter circuit 12 and detects whether or not the count exceeds the reference value B and outputs the corresponding signal to the weighting circuit 11. Thus, jitter in the internal timing is suppressed lower.

Title: Semiconductor substrate
Inventor: NAKAYA TSUNEJI
IPC: H01L21/322
Filed: 1991-04-25
Abstract: PURPOSE:To avoid the particle production due to the exfoliation of strain layer even if a semiconductor substrate is processed with various steps for increasing the manufacturing yield of semiconductor devices, by covering a mechanical strain layer on the rear surface of a silicon substrate with a silicon nitride film. CONSTITUTION:Silicon oxide is blasted on the rear surface of a single crystal substrate by sand blasting step to form a strain layer having strains 2. Next, a silicon nitride 3 is deposited on the strain layer by CVD process. At this time, the high oxidation resistance and etching resistance are given to the silicon nitride film 3. Besides, even if the semiconductor substrate 1 is passed through various manufacturing steps of a semiconductor device, the silicon nitride film 3 is hardly removed. Accordingly, the strains 2 beneath the silicon nitride film 3 are also hardly removed for enhancing the gettering effect. Furthermore, only by depositing the silicon nitride film 3 on the rear surface of the semiconductor substrate 1, the gettering action can be initiated to give intensive gettering force by the gettering effect the mechanical strain and the silicon nitride film 3.

Title: Magnetizing apparatus of radial anisotropic cylindrical magnet
Inventor: HASHIMOTO FUMIO
IPC: H01F13/00
Filed: 1987-04-17
Abstract: PURPOSE:To decrease cogging torque when a magnet is assembled into a motor and to secure the sufficient effective amount of magnetic flux, by applying winding in the state the winding wire parts are aligned on an epproximately straight line from the central part to the outer surface side so that an intermediate part between neighboring magnetic pole parts is divided into two parts. CONSTITUTION:An intense magnetic field is generated in a part close to a winding 14. The magnetic field, which is applied on a cylindrical magnet 10 is aligned in the troidal direction. The radial component of the magnetic field, which is applied on the cylindrical magnet 10, becomes large. The magnetic field is concentrated at a tip part 16a of each magnetic pole part 16. Therefore, the magnetic field in the radial direction become most intense. As a result, the tip of each magnetic pole is magnetized most intensely. A part close to the winding 14 is hardly magnetized. Such a magnetic flux density distribution is formed. Therefore, the magnetic flux density distribution of the magnetized cylindrical magnet 10 forms an approximately sinusoidal smooth curve. Thus an excellent effect for securing the sufficiently effective amount of the magnetic flux for actual use can be obtained. When this part is assembled into a motor as a rotor, cogging torque is decreased, and vibration, noises and the like are also reduced.

IPC: F04D7/02
Filed: 1982-06-04
Abstract: PURPOSE:To enhance the reliability of pump inserting and retracting operation, by providing a float valve in a port of a carier in a vertically movable manner, and thereby making remote operation of a seal valve unnecessary. CONSTITUTION:Since a float valve 6 is pushed upward by the function of buoyancy when it comes to liquid surface 21, liquefied gas is introduced into a carrier 4. When the carrier 4 is lowered further and its conical part 4f comes into contact with a conical part 24a of a lower cover 24, the interface between the two conical surfaces is sealed positively since the pressure at the sealing surfaces of the conical parts 4f, 24a is maintained by the discharge pressure acted to a pump 12. Thus, since remote operation of a seal valve for a high-pressure liquid is made unnecessary, reliability of pump inserting and retracting operation can be enhanced.
