Patent JP-H09182482-A (JP)
Title: Brushless motor
Inventor: GOTO MAKOTO
IPC: H02P6/06
Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To lessen the influence even in case that dispersion occurs in the amplitude of the detection signal of a Hall element or the like by making a distribution signal by the multiplication result of the output signal of a command signal and the corrected output signal of a switching making means, and supplying a drive signal. SOLUTION: This brushless motor makes out a corrective signal which changes in proportion to the amplitude of the detection signal of a position detector 4021, and corrects the amplitude of the output signal of a switching maker 4022 into one corresponding the specified signal. This makes out a distribution signal by the multiplication result of this corrected output signal of the switching maker 4022 and the output signal of a command current apparatus 4050. Accordingly, the amplitude of the output signal of the switching maker 4022 and the amplitude of the distribution signal of a distributor 4031 cease to be influenced by the amplitude of the detection signal of the position detector 4021.  As a result, the drive signal supplied to a three-phase coil ceases to be affected by the dispersion in detection of the position detector 4021, and the dispersion of relation between the command signal and the generated torque ceases to occur.

Title: Crystal oscillator with heat-resistant film
Inventor: YAMAGUCHI HIDEKI
IPC: H03H9/02
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To use a crystal oscillator for the surface mounting soldering by means of a solder dip tank system by forming a heat-resistant coat for a part, except for a part used for soldering the lead of the cylinder-type oscillator where the lead is formed through the use of a metallic package. SOLUTION: Manufacture of a cylinder-type oscillator is automated, and a carrier is used in the manufacture. The carrier loaded with the completed cylinder-type oscillator is transported to a resist coat forming process. A container 16 is filled with heat-resistant resist liquid 15, and the desired part of the cylinder-type oscillator is immersed in resist liquid 15 and is then dried. Since the heat-resistant coat process is added as post process of a series of manufacture processes, it is easy to form the heat-resistant coat and it can inexpensively be formed. Since soldering by the solder dip tank system is executed at 240 deg.C, a thermosetting type epoxy material is used as heat-resistant resist liquid 15, for example.

Filed: 1989-12-08
Abstract: PURPOSE:To dispense with wiring between an exchange unit and a slave unit by performing radio transmission/reception between the exchange unit which performs mutual switching of an extension and a line wire and the slave unit to which a telephone set is connected. CONSTITUTION:The radio transmission/reception circuit 12 of the exchange unit A is divided corresponding to the number of extensions i.e., the number of slave units B, and independent radio transmission/reception between each slave unit B and the exchange unit A is performed. The exchange unit A detects an incoming call from the line wire, and transmits the wave signal of each extension. Each slave unit B, when receiving the signal, rings the bell of a slave telephone set 20 connected to a connector 17. When the handset of either slave unit B is raised, the slave unit B to which the slave telephone set 20 is connected returns an off-hook signal to the exchange unit A.

Filed: 1993-12-20
Abstract: PURPOSE:To change the composition of a refrigerant circulating through a freezing cycle and to improve efficiency by a method wherein lubricating oil in such a manner to have different characteristics from those of a refrigerant is used, and an oil separator having a lubricating oil regulator to control the temperature of lubricating oil is connected to a piping through which a compressor and a condenser are intercoupled. CONSTITUTION:High temperature high pressure refrigerant steam compressed by a compressor 1 is radiated and condensed and liquefied by a condenser 2. Thereafter, the refrigerant steam is reduced in a pressure and expanded by a throttling device 3 and produce a gas liquid two-phase refrigerant. Heat is sucked by a vaporizer 4 and vaporized and gasified to produce refrigerant steam, which is sucked in the compressor 1 again. In this case, lubricating oil during freezing cycle having characteristics differing with the change of temperature and pressure from those of the refrigerant is used. In this case, an oil separator 5 having a lubricating oil temperature regulator is connected to a piping through which the compressor 1 and the condenser 2 are interconnected to control the temperature of lubricating oil. This constitution varies generating capacity by changing the composition of a circulating refrigerant and improves the efficiency.
