Title: Phased array sonar
Inventor: TAKEUCHI YASUTO
IPC: G01S7/521
Filed: 1979-08-29
Abstract: PURPOSE:To increase the overall directive characteristics, by providing the electrode group of unique arrangement on the both sides of electrostriction plate and using the array transducer taking one as transmission and another as reception. CONSTITUTION:According to the indication of the control circuit CNT, the digital timing unit TM gives the drive pulse to the array transducer TD via the drive amplifier group Ad and radiates the ultrasonic wave beam toward one direction. In this case, the reception electrode group 2 is substantially grounded with the operation of the clamp circuit group CL. Next, when the reflection wave to the ultrasonic wave beam is incident to the array transducer TD, the incident signal is picked up with the reception electrode group 2 and the direction of wave surface to be received with the variable delay line group DL is made and the synthesis of reception signal is made with the reception amplifier Ar.

Title: Endoscope optical system
Inventor: KIKUCHI AKIRA
IPC: G02B23/26
Filed: 1988-05-06
Abstract: PURPOSE:To obtain an endoscope optical system which allows to observe a subject image in a clear visual field without being affected by dust and burrs by installing a heterogeneous medium lens whose refractive index becomes smaller as it goes closer to the circumference side from the center so as to satisfy the specific conditions. CONSTITUTION:The bar shaped heterogeneous medium relay lens 11 whose length is 1/2up determined according to a relay number (n) is positioned on the injecting side of an objective lens 1 composed as an afocal system, and a cover glass 12 is adhered on the injecting plane holding a brightness diaphragm 5 in between. The (P) is the pitch (cycle) of the heterogeneous medium lens, and when the distances between an incidence end plane/injection end plane and the subjects M1/M1' formed at the closest position to these planes are represented by C1 and C2, the (P) is composed so as to satisfy the formula I and II. Thus, the position of the incident plane of the lens 11 almost accords with that of an optical system pupil, and scratches, dust, etc. do not appear. In addition, the burrs on the lens end plane are hidden without making the view field small.

Title: Axial type electronic parts separator
Inventor: SHINNO TATSURO
IPC: B65G47/08
Filed: 1985-05-24
Abstract: PURPOSE:To make improvements in separatory performance, by constituting an inverted conical parts housing case, having a rotating parts insetting holes push rod pierceably in the bottom center, and a push rod being relatively free of vertical motions, while making up each part so as to be projected and separated with this push rod. CONSTITUTION:When electronic parts are put in an inverted conical housing case 1, lead wires of parts converge on a bottom part 1a of this case 1. At this time, a push rod 2 is rotated whereby one lead wire of each part so far caught in an edge of an insetting hole 2 of the rod 2 is fitted into this insetting hole 2a. Under this condition, the case 1 or the rod 2 are made to move up and down whereby each part fitted in the insetting hole 2a is projected out of other parts and thus separable. With this constitution, separatory performance is improvable.

Title: Device for reproducing recording medium
Inventor: YAMADA TOSHIHIKO
IPC: G11B19/02
Filed: 1993-05-12
Abstract: PURPOSE:To add a new reproducing function and to use a device in a game feeling by selecting a music in an irregular music order different from the recorded order and reproducing the music for a several seconds by a partial reproducing procedure. CONSTITUTION:A sub code, etc., decoded by a signal processing circuit 13 are inputted to a micro computer 17, and a signal is inputted from an operation switch group 18 to the micro computer 17. Then, by the micro computer 17, a compact disk autochanger 11 is driven and controlled according to these inputs, and further, the mute control, etc., of a low frequency amplifier circuit 15 is executed. In such a case, since after a litsener listened a part of a music, thinks of a music name while reproduction is interrupted for ten seconds, and thereafter (after ten seconds elapses), the listener can confirm a performed music by a reproducing output reproduced again, the reproducing function suitable for a so-called introduction guessing game is realized.

Title: Portable radio telephone
Inventor: OKUHARA SUNAO
IPC: H04W12/02
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To prevent illegal use with good operability and high reliability by providing a locking function which enables an operation unless a picture matched with a previously registered password picture is inputted. SOLUTION: A possessor operates a key input part 5 and therefore it takes in a picture (the picture of the iris of an eye and the picture of a fingerprint, for example) of a physical feature part of the possessor from a lens part 9. The picture taken into a portable radio telephone from the lens part 9 is A/D- processed in a picture processing part 10 and is preserved in a memory part 11 as a password picture. The password picture is inputted to the memory part 11 and therefore a system becomes a dial locking (non-enter of key input part 5) state. When the system becomes the dial locking state, a calling operation is disabled and the set cannot be used. In a method for releasing the dial locking state, the picture similar to the password picture that is previously registered in the memory part 11 can be taken in. The possessor can simply take in the same picture.

Abstract: PURPOSE:To carry out the operations of separating a cleaning roll from a fixing roll and cancelling the pressure of a pressure roll only with the driving source of a main body by attaching a cum which lifts the cleaning member and a cum which cancels the pressure of the pressure roll to the fixing gears. CONSTITUTION:When the rotary force in a rotary direction A is applied to a gear 4 from the driving source of the main body, a gear 14 idles by an one way clutch 12, and a gear 18 idles by an one way clutch 16, whereby the cum 13 and the cum 17 do not rotate. When the rotary force in a rotary direction B is applied to the gears, the cum 13 rotats in the direction of an arrow JC, and the cleaning member 10 is lifted and separated from the fixing roll 3. The cum 17 rotates in the direction of an arrow jE, the lever 6 is pushed up in the direction of an arrow H, and the pressure of the pressure roll 17 is cancelled. Thus the operations of separating the cleaning member 10 of the fixing roll 3 from the fixing roll 3 and cancelling the pressure of the pressure roll 7 can be carried out only by the driving source of the main body.

Filed: 1986-05-16
Abstract: PURPOSE:To prevent the use other than the object of an important line by displaying the reception of a key code number onto a telephone set with a display for a called extension so as to select the opposite party making a call and replying it in detecting a key code number at the incoming call of dial-in information. CONSTITUTION:When dial-in information comes to a central office a central control unit 6 detects the incoming call to connect the central office 4 and a register 5 via a channel switch 3. The register 5 receives and counts dial information and transfers the result to the central control unit 6. When a key code number is informed to the caller in advance together with the telephone number, the caller dials both the numbers. The central control unit 6 identifies the extension number and the key code number, then the key code number is collated with the key code number data decided in advance and when the both are coincident, the incoming call is displayed to the telephone set 1 with display in audible sound and the reception of the key code number is displayed on a display section. The called party may not reply a call without any key code number.
