Title: Differential transformer
Inventor: AOKI KAZUHISA
IPC: G01B7/00
Filed: 1994-05-19
Abstract: PURPOSE:To provide a differential transformer which dose not allow any measurement error to be led even if there exists dislocation in phase between the wave form of the output of a primary coil and the wave form of the output of each secondary coil. CONSTITUTION:In a differential transformer 10 measuring displacement with its probe 14 brought into contact with a measured object 12, the aforesaid transformer is equipped with a core 16 which is moved in response to displacement, a primary coil 18 and with secondary coils 20 and 22. AC voltage is inputted to the primary coil 18 with both its voltage and frequency kept constant, and electro motive force is produced in the secondary coils 20 and 22 as the core 16 is moved. Voltage outputted from the secondary coil 20 is operated as specified, it is inputted into a rectifying circuit 30 thereafter, and it is then chopped on the basis of the voltage of an addition circuit 28 so as to be rectified. Since there is no dislocation in phase between objective voltage for rectifying and chopper voltage, no error appears in DC voltage which is rectified after it has been chopped. By this constitution, no measurement error thereby appears for the displacement of a measured object.

Title: Data receiving device
Inventor: TAKEDA HIDETOSHI
IPC: H04N19/65
Filed: 1995-04-28
Abstract: PURPOSE: To prevent the transfer of data over a band that is previously acquired and to perform the corresponding processing at the reception side when the data are transferred via a communication medium. CONSTITUTION: A necessary band is calculated when the band of the data 108 inputted to a transmitting device 124 is detected and sent to a communication medium 114. This calculated band is compared with the band that is previously acquired from the medium 114, so that the data transfer condition is decided. Then the transfer of the data 108 is stopped when the necessary band exceeds the acquired band, and the band of the data 108 is also sent together with the data. On the other hand, a receiving device 125 performs the corresponding processing based on detection of the data transfer stoppage of the device 124 and on the band of the data 108. Thus it is possible to prevent the transfer of data over the band acquired from the communication medium and also to perform the corresponding processing at the reception side.

Title: Semiconductor device
Inventor: TAJIMA YUTAKA
IPC: H01L27/08
Filed: 1989-04-25
Abstract: PURPOSE:To improve a latchup strength without degrading a breakdown strength even if the size of a transistor is miniaturized by a method wherein an effective impurity concentration of, for instance, an N-type MOS-FET forming region only in the surface layer of a P-type well is reduced and the impurity concentration of the other part is high. CONSTITUTION:A P-type well 2 is formed on an N-type silicon substrate 1. After element regions are isolated by field oxide films 31, gate oxide films 5 and 11 are formed. Then N-type impurity is implanted into a MOS-FET forming region and a thermal treatment is performed to form a region 71 having an effectively reduced impurity concentration in the surface part of the P-type well 2. After that, an N-type channel MOS-FET 70 is formed on the P-type well 2 and a P-type channel MOS-FET 13 is formed on the adjoining substrate 1 and both the FET's provide mutually complementary relation to form a CMOS-FET. By implanting ions into the P-type well 2 with a high energy, a thermal treatment can be reduced and, further, the impurity concentration down to the depth of 1mum can be reduced, so that the degradation of a breakdown strength can be avoided.

Title: Trace control system
Inventor: ONO HIRONORI
IPC: G06F11/28
Filed: 1989-04-27
Abstract: PURPOSE:To easily change a trace point only with the change of a trace point address by carrying out a subroutine call instruction given to a trace routine via a microprocessor when the coincidence is obtained between the trace point address and the microinstruction address to be executed. CONSTITUTION:A comparison means 4 compares the microinstruction address which is received from a microprocessor 1 and to be executed next with a trace point address stored in a trace point store means 3. When the coincidence is obtained between both addresses, a subroutine call instruction stored in a subroutine call instruction store means 5 is carried out by the microprocessor 1 for the execution of branching to a trace routine. In this case, the trace point addresses to be stored in the means 3 can be freely designated from outside. Thus it is possible to change a trace point just by changing a trace point address which is presently stored.

Title: Crank shaft rotating mechanism through piston with slider
Inventor: YOSHIDA SHIZUO
IPC: F16H21/18
Filed: 1983-06-14
Abstract: PURPOSE:To improve the efficiency and make an operation smooth by providing a perpendicular slider chamber on the crank shaft side of a piston and incorporating in this chamber a perpendicular sliding body which is connected to a crank arm. CONSTITUTION:A perpendicular slider chamber 3 is provided on the crank shaft side of a piston 2, and a perpendicular sliding body 4 is incorporated in this perpendicular slider chamber 3, while the sliding body 4 is connected to a crank arm 6 through a crank pin 5. Thereby, since the advancing distance of the piston 2 is just equal to the advancing distance of the crank pin 5 on the center line, the conversion between linear motion and rotary motion can be effectively performed. Furthermore, the advancing modes of the piston 2 when the rotation of the crank shaft is from 0 to 90 deg. and from 90 to 180 deg., are perfectly symmetrical between right and left, while the piston 2 does not generate side pressure against the wall of a cylinder 1, thereby making the operation smooth.

Title: Mass analyzing method
Inventor: MATSUI TEIICHIRO
IPC: G01N27/416
Filed: 1985-05-17
Abstract: PURPOSE:To realize highly sensitive ion detection by giving inflection so that a DC voltage has the same polarity as that of other region of scanning locus with the mass numbers of almost 0 to 1, thereby a DC voltage does not become 0 before a high frequency voltage becomes equal to 0. CONSTITUTION:With increase of a high frequency voltage V to be applied to a pair of quadra-pole electrode Q, a DC voltage U to be applied to the same electrode also becomes higher. When a value U is higher than a DC power supply Up, d2 is in the OFF state and the value U changes in accordance with change of V. When U becomes lower than Up, d1 is set to the OFF state and a DC voltage applied to the quadra-pole becomes equal to a constant value Up. A DC voltage U to be applied to another pair of quadra-pole electrode Q is output through a diode d1' after polarity of an output of subtraction circuit SB is inversed by an inversion circuit In. When it becomes lower than the DC power supply Up', d1' is set to OFF state and a constant voltage Up' is applied through d2'. Thereby, peak of mass number 1 can be detected separately and thereby highly sensitive ion detection can be realized for the total mass range.

Abstract: PURPOSE:To improve the intake efficiency and the output of an engine by opening a subintake passage towards the lower half of a crank chamber where the intake density lowers and supplying intake into the lower half of the crank chamber from the subintake passage and obtaining a uniform intake density in the crank chamber. CONSTITUTION:If a piston 17 rises in the intake cycle, a negative pressure is generated in a crank chamber S, and the mixed gas generated in a carburetor 11 is introduced into the crank chamber S through the main and subintake passages 10a and 10b and lead valves 19 and 20. Since, at this time, the busintake passage 10b is opened between the both webs 5a and 5b of the both web shafts 5 of a crankshaft 5, the part between the webs 5a and 5b whose intake density is low in the conventional is charged with intake. Therefore, the reduction of the intake density in this part can be prevented, and the intake density in the crank chamber S is kept nearly constant. Therefore, the intake efficiency is improved, and the output of a two-cycle engine is improved.

Abstract: PURPOSE:To obtain the voice output which can be understood easily by referring to an abbreviation word number, and converting it to an abbreviation name to a formal name, based on a result of decision of a deciding means in accordance with an abbreviation conversion mode. CONSTITUTION:A text character-string inputted from a text character-string input terminal 11 is sent to a text analyzing part 12, and collated with a word stored in a work dictionary 13. Subsequently, the character-string is divided into phrases and words, and reading of the divided word is determined. In such a state, when '1' is set in a formal name flag 13a of the dictionary 13, reading of a certain abbreviation name exists in its word, therefore, a deciding means 12a of the analyzing part 12 decides that there is reading of an abbreviation. These words decided to have reading of an abbreviation are all sent to an abbreviation converting part 17, and based on an abbreviation conversion mode 17a determined in advance, an abbreviation conversion processing is executed. As a result, since a long formal name is replaced with an abbreviation name and outputted in a voice, a voice output for taking a hearer's understanding level into consideration can be obtained easily.
