Title: Microwave band transmitter-receiver
Inventor: SATO TAKESHI
IPC: H04B1/40
Filed: 1986-12-10
Abstract: PURPOSE:To attain small size with simple constitution by connecting an output power amplifier and a reception amplifier directly to a cross polarized wave branching filter and locating a trap conductor rod to a waveguide placed at the input side of the cross polarized wave branching filter or the receiving amplifier. CONSTITUTION:A conductor rod 6 is placed in parallel with the plane E to the waveguide side of a coaxial waveguide converter 5. In placing the conductor rod 6 to the waveguide, series resonance takes place in case of h=lambda/4 (lambda is wavelength). As a result, a trap is formed by placing the conductor rod 6. In selecting an (h) corresponding to a transmission frequency, e.g., 14GHz, the transmission signal of 14GHz is attenuated by nearly 13dB. Through the constitution above, the transmission signal invaded to the reception side via the cross polarized wave branching filter 1 is attenuated remarkably. As a result, the improvement of the performance is realized by installing the conductor rod without introducing a waveguide filter whose characteristic depends on the shape and the size of the device is miniaturized.

Title: Measuring apparatus for inclining angle of moving body
Inventor: KANDA TOSHIHIKO
IPC: G01C9/08
Filed: 1990-10-31
Abstract: PURPOSE:To reduce accumulating errors of the inclining angle obtained by integrating outputs of an angular velocity sensor and to obtain the correct inclining angle by resetting the output of an integrator every time it is judged that a moving body is stopped. CONSTITUTION:An angular velocity sensor 1 detects the inclining angular velocity of a bulldozer and a vehicle velocity sensor 2 detects the velocity of the bulldozer. The detecting result of each sensor is input to an inclining angle operating device 3. An integrator 4 of the device 3 integrates the inclining angular velocity input from the sensor 1 thereby to operate the inclining angle with using zero as an initial value. The inclining angle output from the integrator 4 is used as a signal taken into a device which detects the position of the body of the bulldozer in the vertical direction through integration of a multiplied value of the angle and vehicle velocity. A vehicle velocity detector 5 detects when the input vehicle velocity from the sensor 2 is not larger than a set velocity, thereby judging a time point when the bulldozer is brought to a halt, that is, when the bulldozer finishes one cycle of work, and sets the angle integrated by the integrator 4. Accordingly, the integrator 4 outputs the relative inclining angle for every cycle of operation to a reference inclining angle when the bulldozer starts working.

Title: Fixing temperature controller for image forming device
Inventor: TAKAHASHI MASARU
IPC: G05D23/00
Filed: 1988-11-24
Abstract: PURPOSE:To prevent the occurrence of smoking from a jammed paper and the deformation of a gear, etc., made of synthetic resin caused by abnormally high temperature by using a thermistor with high accuracy and a thermistor excellent in mechanical strength jointly and detecting the occurrence of defective contact by the latter when the defect in contact occurs in the former. CONSTITUTION:The precise fixing thermistor 9TH(1) and the thermistor 9TH(2) functioning as an auxiliary thermistor with excellent mechanical strength, whose accuracy is inferior to that of the thermistor 9TH(1), are used jointly. A comparator 24 compares the output voltage e1 of the thermistor 9TH(1) with the output voltage e2 of the auxiliary fixing thermistor 9TH(2) and when a difference voltage e0 is outputted, a comparator 25 compares the difference voltage e0 with a reference voltage VREP and a thermistor error signal is generated. That means, an abnormal state such as the disconnection or the short-circuit of the fixation thermistor 9TH(1) or the detection of high temperature or low temperature can be detected with accuracy rather than detected by one fixing thermistor, because the comparators 24 and 25 are allowed to operate based on the detection output from the auxiliary fixing thermistor 9TH(2). Thus, the occurrence of smoking from the jammed paper and the deformation of the gear, etc., made of the synthetic resin in the fixing unit can be prevented.

Title: Method of encoding optical packet and switching node
Inventor: RICHIYAADO DEII GITORIN
IPC: H04L12/56
Filed: 1991-10-16
Abstract: PURPOSE: To avoid the limitation by a high-speed electronic circuit by eliminat ing the need of the electronic circuit of a switching node operating at the bit rate of a high-speed link. CONSTITUTION: A part of a packet signal comprising a header section having a low-speed rate and a data section having a high-speed rate is transmitted to a low-speed receiver 34 through an optical coupler 32 and the most of the packet signal is transmitted to an optical switch 40 through a delaying section 36. The low-speed receiver 34 guides the signal to a low-speed electronic control 38 by reading the packet header so as to control the destination of an optical signal from the delaying section 36. Therefore, a switching node is not required to process the data section of the packet, but the header section only. In addition, the high-speed data section of the packet merely passes through the switching node.

Title: Thin film magnetic head
Inventor: SHOJI SHIGERU
IPC: G11B5/17
Filed: 1988-11-22
Abstract: PURPOSE:To evade contact of a conductor with adjacent conductors in a coil causing deterioration in the accuracy of exposure and to improve the yield of the coil by selecting the conductor of the coil wider toward the upper layer of the coil and selecting the thickness of the coil so as to make the electric resistance of each layer equal to each other. CONSTITUTION:A lower protection layer 2, a lower layer core 3, and a gap layer 4 are formed in order on a wafer substrate 1 of a magnetic head and 4 coils are formed as a layer via an insulation layer 5 on the gap layer 4 and an upper layer core 7 is provided to the uppermost part. The interval and the width of the conductor made of the coil 6 in the lower layer are decreased and the thickness is made thick to increase number of turns of the coil so as to avoid the accuracy of exposure due to the reduction and ununiformity of the resist coating thickness attended with the multi-stage lamination at the coil forming. Then the interval and width of the conductor is more increased toward the upper layer and the thickness of the coil is made thinner so as to make the electric resistance in each layer equal to each other. Thus, the contact of the plating in the forming of the coil through the resist is prevented.
