Title: Voltage controlled frequency synchronization oscillator
Inventor: SHIGAKI MASAFUMI
IPC: H03D13/00
Filed: 1993-02-24
Abstract: PURPOSE:To obtain a low noise signal at a more stable frequency by connecting a phase shifter whose phase shift is changed with a control voltage to any position among for positions at each of pre-stage and post-stage of reference and comparison lines so as to obtain an optional frequency signal. CONSTITUTION:A signal via a reference line 3 and a phase shifter 5 and a signal via a comparison line 4 are inputted to a mixer circuit 7, in which the phases of the signals are compared. The result of comparison as an error signal is inputted to a voltage controlled oscillator 1 via a loop filter circuit 8. That is, the oscillating frequency of the oscillator 1 is controlled in response to the error signal received via the circuit 8 and the oscillator 1 outputs a signal 2. Since a phase shift of the phase shifter 5 varies with a control voltage 6, a desired frequency signal 2 is obtained by setting the control voltage optionally. As a result, an event of obtaining only a single frequency signal 2 is avoided and the desired frequency signal is obtained even when the phase shifter 5 is connected to any of pre-stages and post-stages of the reference line and the comparison line 4.

Title: Communication equipment
Inventor: SUZUKI TOSHIROU
IPC: H04B3/14
Filed: 1981-03-11
Abstract: PURPOSE:To accurately adjust phase synchronism, an f<1/2> equalizer, and a BT equalizer by transmitting a 0-cross signal, a signal of a low frequency component, and a random signal of a wide frequency range spectrum in order to a terminal equipment coupled with a subscriber line with BTs. CONSTITUTION:From the phase synchronous training TRG signal generator 7 of a transmitting terminal 16 coupled with a telephone subscriber line 3 with free circuit branches BT4-1-BT4-3, a signal having a 0-cross at the best discrimination point is sent to a receiving terminal 17 through a switch SW14. The best discrimination timing is determined by receiving said signal by the phase synchronizing circuit 11 of the receiving terminal 17 to operate an SW15, and an equalized digital output is supplied from a discriminator 13 to the terminal 6. Then, a signal TRG having a low frequency component is sent from an f<1/2> equalizer TRG signal generator 8. At a reception side, the signal is received to adjust an f<1/2> equalizer 10. From a BT equalizer TRG signal generator 9, a pseudo-random signal having a wide frequency spectrum range is sent to adjust the BT equalier 12 of the reception side. After TRG, the SW14 connects the subscriber line 3 to a terminal 5 to carry out ordinary communication.

Filed: 1994-03-04
Abstract: PURPOSE:To quickly provide a highly accurate curved surface in three- dimensional curved surface working. CONSTITUTION:A curved surface working CAM system for inputting requested shape data and outputting tool route data executes tool route calculation for generating irregularity in the intervals of tool route dots in a tool advancing direction and the pick feeding intervals of the tool route by adopting hierarchical structure shown by a quarter tree as the data structure of a requested face mesh and offset face data to be used for a processing process for generating an offset face and utilizing the fineness of patches constituting the offset face and their adjacent ralation for dot intervals on the tool route. Consequently the quantity of data to be required for working a highly accurate curved surface can be reduced and the cutting work time of an NC machine tool in the three- dimensional curved surface working can be shortened. Thereby a highly accurate curved surface can quickly be provided.

Title: Bag for freeze-preservation
Inventor: YUASA TAKESHI
IPC: A61J1/10
Filed: 1995-01-31
Abstract: PURPOSE: To retard the damaging of cells in a component to be frozen by forming island-shaped or cape-shaped sealing parts in a bag part so that the swelling of the bag part is divided into a plurality of smaller portions when it is filled with a liquid matter to reduce the tendency of enhancing the crystal of water in blood components when the bag is frozen. CONSTITUTION: Island-shaped sealing parts 3 are formed vertically in a bag part 2 of bag 1 for freeze preservation at four points, for instance, so that the bag part is divided into a plurality of swellings 9 by the island-shaped sealing parts 3 when a blood component is poured into the bag 1. In the use of the bag 1 for freeze preservation, after a protector 4 is unsealed, a plastic bottle needle is stuck into a port to transfer the blood component into the bag part 2. Then, the blood component is preserved being frozen by a heat sealing at a position a-a at an upper part of the bag. This can reduce the tendency of enhancing the crystal of water in the blood component when the bag is frozen thereby retarding the damaging of cells in the component to be frozen. This also eliminates the need for preservation once housed into a carrier for the bag.

Title: Manufacture of high toughness 9% ni steel
Inventor: NAKAMURA MASAAKI
IPC: C21D8/00
Filed: 1984-02-24
Abstract: PURPOSE:To obtain a high toughness 9% Ni steel by specifying temp. conditions during the hot rolling of a slab as a blank and the following hardening and by carrying out tempering after the hardening. CONSTITUTION:A 9% Ni steel slab contg. 8.50-9.50% Ni as a blank is heated at <=1,100 deg.C low temp., hot rolled at >=800 deg.C finishing temp., and cooled preferably by water cooling. The hot rolled steel is hardened by heating at a low temp. between the Ar3 transformation point and 800 deg.C, preferably at 720-760 deg.C, and it is tempered. Since the slab is heated at said low temp., the gamma-grains are made fine after the rolling. The rapid cooling after the rolling makes the gamma-grains fine and uniform during the following hardening, and the structure is made fine by reducing the heating temp. during the hardening. Accordingly, the strength of the steel is increased, and the Charpy toughness can be stabilized at a high level.

Abstract: PURPOSE:To enable an amount of blown air to be maintained when blowing air temperature is decreased under a specific capability control of an inverter by a method wherein a blowing temperature selection switch is arranged at an operating part and a blowing air temperature sensed by a sensor for sensing the temperature of blowing air which is arranged at a main body of equipment is controlled in such a way as it may become a value set by the blowing air temperature selection switch. CONSTITUTION:A blowing air temperature is selected to a value of, for example, 50 deg.C with a blowing air temperature selection switch 10 and then a heating operation is started. As the temperature of a heat exchanger 6 sensed by a thermistor 7 becomes more than 20 deg.C, a hot starting operation is released, a fan 5 is rotated to blow ultra-fine air, the temperature of blowing air is detected by a thermistor 8. When the blowing temperature does not reach to 45 deg.C, the number of revolution of a motor 4 is decreased by 100 rpm than a predetermined number of revolution in order to increase air temperature, an increase in decreased air speed is controlled to generate an air flow of spot condition A by concentrating vanes 2 and 3 by 10 deg. without increasing the amount of air. In this case, air speed is not restricted more than a reduced flow condition defined in relation to the positions of the vanes 2 and 3 and the number of revolution of the motor 4 in such a manner as it may not exceed a certain predetermined value.
