Title: Analog signal generator
Inventor: KOBAYASHI SADAO
IPC: H03J5/02
Filed: 1983-12-29
Abstract: PURPOSE:To handle a receiver which switches its source voltage according to reception bands by switching the source voltage applied to an analog signal generating circuit when the frequency division ratio of a PLL is varied with an analog signal. CONSTITUTION:This receiver controls the program frequency divider 5 of the PLL circuit to the control voltage of an analog signal generating part 1, which consists of a reference frequency oscillator 6, counter 7, signal mixer and voltage switch 8, pulse-voltage converting circuit 9, and analog signal generator 10. The counter 7 and mixing and switching part 8 switch and output pulses with a period corresponding to the source voltage used by the receiver. The converting circuit 9 integrates the applied source voltage by the period of said pulse signal and applies the result to the analog signal generator 10. Consequently, a constant voltage is applied to the generator 10 regardless of the switching of the source voltage.

Title: Front end for digital satellite broadcast receiver
Inventor: AMANO SHINJI
IPC: H04B1/26
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a front end for digital satellite broadcast receiving adopting a direct conversion system by which the occurrence of input local leakage can be prevented and the excellent operating characteristic of its oscillation circuit can be obtained. SOLUTION: This front end comprises a filter 2 that receives a reception signal, an oscillation circuit 7 that oscillates a signal with a frequency being a multiple of n-fold frequency of the received signal, a frequency divider 6 that divides the signal outputted from the oscillation circuit 7 to 1/n, a 90 deg. phase shifter 5 that receives a signal outputted from the frequency divider 6, and mixers 3, 4 that mix the signal outputted from the filter 2 with a signal outputted from the 90 deg. phase shifter 5. Since the oscillation circuit 7 is oscillated with the frequency being a multiple of n of the frequency of the received signal, the filter 2 can shut off a leakage of a local oscillation signal to the input signal. Furthermore, since the oscillation circuit 7 hardly receives the effect of the received signal, the oscillation circuit 7 stably oscillates the oscillation signal.

Title: Wholly movable waterproof louver
Inventor: SHIBANO HIDEHIRO
IPC: E06B7/084
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To provide a wholly movable waterproof louver doubly preventing rain on the inside and outside at the time of strong wind and rain by fitting moving blades in opposite directions to inner and outer sections via blade fixing shafts, and allowing the outer blades to be operated and overlapped by the force of wind. SOLUTION: Each outer blade 7 has a larger area at the lower portion than at the upper portion across a blade fixing shaft 9 to effectively utilize the force of wind, and the tip section of the upper portion from the blade fixing shaft 9 is folded to keep the balance of weight. Since the wind passing through the space of the portion of the outer blade 7 enters upward, the tip section of the upper portion of each inner blade 8 is not folded so that the inner blade 8 is easily operated and the upper portion from the blade fixing shaft has a large effective area to receive wind. The outer blades 7 are first operated to interrupt the communication between the inner and outer spaces and to prevent wind and rain at the time of strong wind and rain. When the outer blades 7 are made inoperable due to breakage or the like, the inner blades 8 can be operated to prevent wind and rain.

Title: Automatic welding equipment
Inventor: ANAMIZU TAKASHI
IPC: B23K9/09
Filed: 1998-09-02
Abstract: PROBLEM TO BE SOLVED: To provide an automatic welding machine that gives no adverse effect to an electric circuit even if a welding head is attached onto an insulator. SOLUTION: A pulse motor driving circuit 2 in an NC device 1 gives a command pulse to a pulse motor 4 installed in a welding head 3, and drives the motor so that a welding torch comes to a welding torch position determined by the NC device 1. The housing of the pulse motor 4 is insulated from the ground while the entire electric circuit is grounded only on the side of the pulse motor driving circuit 2 of the NC device 1. Consequently, as in the case of the welding of a plastic lined steel pipe, no adverse effect is given to the electric circuit even if the housing of the pulse motor 4 is not grounded by attaching the welding head 3, through an insulator, to an object to be welded since the circuit is originally designed on the assumption that the housing is used without grounding.

Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To enhance the tight contact force of a light shielding film with a lens barrel at the time of incorporating the light shielding film in a camera and to make a light shielding effect high by providing a fluororesin layer and a synthetic resin layer formed on the fluororesin layer. SOLUTION: The synthetic resin layer 2 is provided on one surface of the fluororesin layer 1. The layer 1 is equipped with a through-hole 3 provided to insert a lens barrel in the case of incorporating the light shielding film in the camera and an adhesive layer 4 provided at the edge of the outer periphery of the layer 2 in order to fix the light shielding film in a camera body. In such a case, the light shielding film is fixed in the camera body by means(for example, fusion) other than adhesion, so that the adhesive layer is omitted. The light shielding film is formed like a disk, but it may be formed in optional shape like a rectangle, or the like, if the light shielding frame can be incorporated in the camera.  Thus, the light shielding film is always brought into tight- contact with the lens barrel by the large dimensional recovering force (tightening force) of the synthetic resin layer.

Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To reduce current consumed at various input signal levels by feeding back the output of the CMOS inverter column of an even-numbered stage whose input is signals inputted to an input terminal to the input and performing operation as a pull-up or pull-down circuit. SOLUTION: The signals at a low level, inputted to the input terminal 12 are inputted through a resistor 13 to a CMOS inverter 14, inverted to a high level by the CMOS inverter 14 and supplied to the input terminal of the CMOS inverter 15.
