Title: Recording system for macbain balances and the like
Inventor: DUBREZ HENRI
IPC: G01G3/02
Filed: 1965-01-08
Abstract: 1,096,121. Measuring weight electrically. COMMISSARIAT A L'ENERGIE ATOMIQUE. Jan.8, 1965 [Jan. 10, 1964], No.922/65. Heading G1N. Extension of a spring in, for example, a balance, is measured by attaching a magnetically permeable mass 2, Fig. 2, to its lower end, and measuring the current required in a solenoid 6 in order to hold the mass in a given position. The solenoid is connected in one arm of a bridge circuit, an inductance 10 being connected in a second arm to balance the solenoid inductance, and the solenoid current is varied by varying the voltage applied to the bridge from an autotransformer 15. The top of the autotransformer is moved by a motor 16 when the relay contacts 20 are closed; and with the bridge initially balanced by means of a potentiometer 11 with the mass 2 outside the solenoid, the motor increases the bridge voltage until the mass 2 is drawn far enough into the solenoid 6 to unbalance the bridge. The bridge unbalance voltage is detected at 18, and this opens the relay contacts 20 to de-energize the motor and prevent further increase in the bridge voltage. A recorder 17 monitors the bridge voltage required to hold the mass 2 in the given position. The mass 2 may be a ferrite slug covered with a sheath of glass, and the spring-mass assembly is contained in a glass envelope. The balance may be used for weighing a substance undergoing chemical or thermal reaction as a means of analyzing the substance. A plurality of balances may be monitored at will by means of a rotary switch connecting them in turn to the bridge circuit.

Title: Optical scanning device
Inventor: NARISAWA HIDETSUGU
IPC: G02B26/10
Filed: 1998-01-05
Abstract: PROBLEM TO BE SOLVED: To reduce the focus displacement and the misalignment on a surface to be scanned while increasing the output power of a scanning light beam. SOLUTION: In this optical scanning device 20A, an image forming magnification in the sub-scanning direction is increased by arranging a cylindrical lens 11 having a long focal distance while an image forming magnification in the main scanning direction is decreased by arranging a collimator lens 12 having a long focal distance, thereby making the image forming magnification in the main scanning direction to be below the image forming magnification in the sub-scanning direction. By arranging the collimator lens 12 having the long focal distance, an interval between a light source 1 and the collimator lens 12 is widened and the focus displacement and the misalignment on a surface to be scanned 19 are reduced even when the interval is varied by a temp. change and vibration.  Since a light beam whose width is winder than heretofore is taken in as a scanning beam by arranging the cylindrical lens 11 having the long focal distance, the output power of the scanning beam is increased.

Title: Vertical magnetic recording head
Inventor: TANAKA MOTOHARU
IPC: G11B5/127
Filed: 1981-01-05
Abstract: PURPOSE:To improve the efficiency of magnetic energy in recording and reproduction  and an S/N ratio in reproduction, by arranging a main magnetic pole and a yoke auxiliary magnetic pole in combination on the magnetic layer side of a magnetic recording medium, and thus forming a closed magnetic path to the magnetic recording  medium. CONSTITUTION:To record information in a magnetic layer 6, a current which corresponds to the information is flowed through a coil 4 wound around a main magnetic  pole 3. To reproduce the information, the information is detected by outputting a current flowing through the coil 4. In this case, a yoke auxiliary magnetic pole 9 is so  shaped that a closed magnetic path is formed through a recording medium A and the  auxiliary magnetic pole 9 from the main magnetic pole 3; the area S of the auxiliary  magnetic pole facing the surface of the magnetic layer 6 is made greater than that of  the tip of a magnetic axis 1, thereby improving the efficiency of magnetic energy and  an S/N ratio during reproduction. Further, the tip part of the magnetic axis 1 is in contact with the surface of the magnetic layer 6 at right angles all the time, and a fine  space is left between the auxiliary magnetic pole 9 and the surface of the magnetic layer 6, so that only detected magnetic flux from the main magnetic pole 3 is read out  as the output of the coil 4.

Abstract: PURPOSE:To obtain a privacy telephone set having a large privacy effect with simple constitution, by providing the first cipher part having the second frequency converting means for obtaining the first privacy signal by converting a frequency of the first adding signal by the second local oscillating signal. CONSTITUTION:In case when the first sound signal Si1 being an object of privacy, which has been supplied to an input terminal 1 becomes the first privacy signal S3 as shown in the figure, in the first cipher part consisting of a local oscillator 13, a frequency divider 14, multipliers 2, 4, and an adder 3 in the first constituting part CRD1, a signal component of the first privacy signal S3 becomes frequencies f8, f9-f10, f11-f12, and f13-f14 as shown in the figure, but each frequency component of the privacy signal becomes a state that a frequency area of each frequency component is superposed on each other in a complicated aspect, therefore, the first privacy signal S3 becomes a signal whose meaning is unknown entirely in an aural sense. This first privacy signal S3 is transmitted through a transmission line and thereafter, the decoding processing is executed in the first decoding part in the second constituting part CRD2, and the original signal Si1 is restored.

Filed: 1990-01-08
Abstract: PURPOSE:To decrease the induction of noise from both sides of a track width and to enhance S/N by forming upper and lower magnetic materials only near the head gap to the same track width. CONSTITUTION:The upper and lower magnetic materials 1, 2 are simultaneously worked with the same mask 4 near the gap to equal to track width of the upper and lower magnetic materials 1, 2. Since the track width of the upper and lower magnetic materials 1, 2 is equal in such a manner, the misregistered formation of the upper magnetic material 1 and the lower magnetic material 2 and the need for considering the dimensional errors of the upper and lower magnetic materials 1, 2 are eliminated and the setting of the broad track width is possible. The induction of the unnecessary signals of the adjacent tracks, etc., as noises is obviated and the S/N is improved.
