Title: Disconnection detector of field winding of synchronous machine
Inventor: YAMAMOTO TOSHINOBU
IPC: H02K11/00
Filed: 1988-09-19
Abstract: PURPOSE:To protect a semi-disconnection state by providing a timer means for outputting the disconnection detection signal of a field winding when an apparent temp. equivalent signal deviates from a tolerance range of an estimated normal temp. equivalent signal. CONSTITUTION:When field voltage is varied, a field current waits for time delay for the inductance of a field winding 2 to follow field voltage and, therefore, a time for waiting until a transient phenomenon is eliminated becomes necessary before an apparent temp. equivalent temp. Tf1 becomes a correct value and this time is also contained in the time setting of a timer means 11. Therefore, the operation of the timer means 11 shows that the transient phenomenon is eliminated and the apparent temp. equivalent signal Tf1 has the allowance of an allowance signal Tds and a state becoming higher than field winding temp. at a normal time is continued. In this case, the disconnection state of the field winding equal to an increase in field winding resistance is converted to apparent temp. which is, in turn, compared with the estimated value of normal field winding temp. to detect that the apparent temp. becomes higher and, therefore, only the apparent temp. value due to an abnormal state can be detected.

Title: Digital data receiver
Inventor: MOGI HISAO
IPC: H04N7/16
Filed: 1982-12-24
Abstract: PURPOSE:To prevent data error due to noise generated periodically by taking a digital data as an effective digital data when >2 digital data are coincident among those transmitted for plural number of times in a receiver for scramble broadcast. CONSTITUTION:The same digital data SDATA is transmitted by being superimposed on a video signal Si in a period not coincident with noise generated periodically in a digital data transmission. When at least two digital data SDATA are coincident among the digital data obtained at the receiving side, the coincident data is taken as the effective digital data S*DATA. Thus, the digital data SDATA representing an address code and a key code is obtained without any effect of corona noise.

Filed: 1988-09-19
Abstract: PURPOSE:To organize called terminal equipments even if plural terminal equipments exist in the same communication mode and in the automatic reply mode on the same subscriber bus by allowing the user to input the reply priority. CONSTITUTION:The reply priority is displayed on a display device 120, the user inputs priority properly in the setting of the automatic reply mode and the inputted reply priority is stored in a storage device 110. A short timer value is set to a table 200 to decide a timer value 220 when the priority 210 is high and a longer timer value is preset when the reply priority 210 is low. In the setting of the automatic reply mode, when a call set message is received, the reply priority 210 is read from the storage device 110 and the timer value 220 to retard the reply message is decided from the table 200 according to the reply priority 210. A timer is started in response to the timer value 220, a reply message is sent after timeout and the reply message is sent earlier from a terminal equipment with higher reply priority 210. Thus, the reply is given to an incoming call sequentially from a terminal equipment with higher reply priority 210.

Title: Magnetic head
Inventor: OTA HIROYUKI
IPC: G11B5/235
Filed: 1989-09-11
Abstract: PURPOSE:To allow the formation of a gap with high reliability by butting a pair of core blocks consisting of a magnetic material against each other and joining the core blocks with nonmagnetic films contg. at least one kind of Cu, Au and Ag or the alloy thereof. CONSTITUTION:The nonmagnetic films 3 constituted of the 1st layer film 3A consisting of Al2O3 or SiO2 and the 2nd layer film 3B consisting of at least one kind of the Cu, Au and Ag or the alloy thereof are formed on the gap forming surfaces of a pair of the core blocks 1A, 1B. The core blocks are butted against each other with a groove 4 for a winding window positioned on an inner side and are heated and compression bonded at the temp. below the m. p. of the 2nd layer film 3B. The core blocks are thus joined by the self-fusion of the 2nd layer film 3B. The 1st layer film 3A prevents the diffusion of the material of the 2nd layer film 3B to the core blicks 1A, 1B. The 2nd layer film 3B is the metal which is nonmagnetic and has small activation energy, and the film is thus easily diffusible and makes self-fixing. The exact gap length is thus obtd. and the gap is formed with the high reliability.

Title: Internal voltage generating circuit
Inventor: CHO SHUJIN
IPC: G11C11/401
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous operation of a chip to expand the operation life of the chip by generating an internal voltage and boosting voltage through discrimination of the normal operation mode and stress operation mode in the stress voltage section. SOLUTION: A differential amplifier 101 inputs a voltage which has been divided from the reference voltage (VREF) and an internal Voltage (VINT) with resistors 103, 104 and then inputs an output to the gate of a PMOS transistor(Tr) 102. A clamp circuit 300 controls the clamping of VINT which is reduced from the external power supply voltage (Vext) as much as the threshold voltage Vt of Tr 102. Therefore, in the stress operation mode A, the VINT and boosting voltage (VPP) rise as increase of Vext in the stress voltage section of Vext. Moreover, in the normal operation mode B, VINT and VPP are held as in the case of the clamping section independently of an increase of Vext. Thereby, erroneous operation of chip can be prevented and operation life can also be expanded by discriminating the modes A and B.
