Patent JP-H0392181-A (JP)
Title: Microwave probe apparatus
Inventor: HATTA SHINJI
IPC: A61N5/02
Filed: 1989-09-05
Abstract: PURPOSE:To efficiently heat the body cavity by providing an enlarged part to the probe inserted in the body cavity and mounting a plurality of microwave emitting means to the outer or inner periphery of said expanded part. CONSTITUTION:An expansible balloon 11 as an expanded part is provided to the leading end of a probe 10 and a plurality of microwave emitting means, for example, antennae 12, 12, 12 are radially provided to the outer peripheral surface of said balloon in a close contact state at an equal interval. A control part 4 operates a microwave oscillator 2 and, when the microwave emitted from the microwave oscillator 2 is supplied to the probe 10 through a microwave connector 3, the microwave irradiates the body cavity from the antennae 12, 12, 12. In this case, since the antennae 12 are in contact with the inner wall of the body cavity, the energy loss of the microwave is eliminated and the entire periphery of the inner wall of the body cavity can be efficiently heated by the microwave.

Title: Rotary transformer
Inventor: FUKAGAWA TAKASHI
IPC: G11B5/02
Filed: 1993-09-16
Abstract: PURPOSE:To reduce the amplitude of the output voltage of a recording amplifier easily in a simple constitution thereby to lower the voltage of the power source of the recording amplifier without increasing the voltage of the power source even when the frequency of a recording signal becomes high during recording. CONSTITUTION:A middle tap 1c is connected to a coil 1a of a stator of a rotary transformer 1 so that the ratio of the number of turns of the coil 1a the stator to a coil 1b of a rotor is, for instance, 1. When the rotary transformer 1 is used in a magnetic recording/reproducing apparatus, the middle tap 1c is connected to a recording amplifier 5, thereby the amplitude of the output voltage of the recording amplifier in recording is made smaller than in a conventional manner easily in a simple constitution. Accordingly, the voltage of the power source for the recording amplifier in recording is naturally decreased.

Title: Insulating type direct current to direct current converter
Inventor: SAKIYAMA KOUJIROU
IPC: H03K7/08
Filed: 1982-12-27
Abstract: PURPOSE:To obtain an insulating type DC-DC converter which allows accurate measurement of temperature, etc., by a thermocouple, etc., by providing a switching element for latch-up prevention on a pulse-width conversion output side. CONSTITUTION:When a DC exciting current enters a plus regions as a DC control input increases, negative feedback operation changes into positive feedback operation and a circuit constituted as shown in a figure is latched up. This latch-up state is prevented by turning on a transistor TR3 as the switching element for latch-up prevention when such a DC exciting current that the output voltage after pulse-width conversion goes beyond a measurement range, i.e. negative feedback current flows, exciting saturable reactors M2 and M3 reversely. Therefore, the current returns to the region where the output voltage after the pulse-width conversion increases in pulse width, i.e. normal measurement range.

Title: Mounting apparatus for chip electronic component
Inventor: ITAGAKI MASATO
IPC: H05K13/04
Filed: 1987-09-14
Abstract: PURPOSE:To mount an electronic component highly accurately by a method wherein a mounting head which has sucked the electronic component and a position-and-posture correction mechanism are turned in advance to an angle corresponding to an instructed mounting angle of the electronic component on a printed-circuit board before they reach a position-and-posture correction station. CONSTITUTION:An angle of an electronic component which has been vacuum-sucked from a component-feed device 2 by using a mounting head 3 in a suction station S1 is determined at an instructed mounting angle by turning the mounting head 3 by means of an angle-determining mechanism 12 in a station S2. Then, until the mounting head 3 is shifted to a station S3, a position-and-posture correction mechanism 7a or 7b is turned and positioned at the instructed mounting angle nearly in synchronization with an intermittent turning operation of an index turning disk 4, and is on standby. Then, the mounting head 3 is lowered and executes only a position-and-posture correction operation of the electronic component. After that, a detection device 8 detects a position and a posture of the electronic component in a station S5; the mounting head 3 mounts the electronic component on a printed-circuit board 5 on an X-Y table 6 in a next mounting station S6.

IPC: G06F19/00
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To fast simulate the operation of a circuit in the parallel processing by extracting a part undergoing the synchronous processing according to a signal change as a synchronous part, extracting a part which performs the signal assignment within the synchronous part as a signal assignment part, and then dividing the signal assignment part from a sequence processing description. SOLUTION: A sequence processing decision part 1 decides whether or not a sequence processing description is included in the description of an HDL (hardware description language).

A signal information acquisition part 3 extracts a part which performs the signal assignment within the synchronous part extracted at the part 2 as a signal assignment part. Then a division part 4 divides the signal assignment part extracted at the part 3 from the sequence processing description.

Title: Biological sound detector
Inventor: SUZUKI HIDENORI
IPC: A61B7/04
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To provide a biological sound detector capable of outputting signals not including the signals other than biological sound generated inside the body of a person to be measured. SOLUTION: Since a tightly closed air chamber 66 is provided between a case body 22 and a microphone 40, environmental noise transmitted from the outside of a living body through the air and reaching the case body 22 is reflected or absorbed in the air chamber 66. Also, since the air chamber 66 is tightly closed, the environmental noise does not resonate inside the air chamber 66 either. Thus, the vibration of the diaphragm 50 of the microphone 40 positioned on the inner side of the air chamber 66 inside the case body 22 by the environmental noise is suppressed.
