Title: Head serching method of cassette tape recorder
Inventor: OGIUCHI TAKASHI
IPC: G11B15/00
Filed: 1984-02-29
Abstract: PURPOSE:To search a head of a tape with high reliability and accuracy and little abrasion of a reproducing head by winding a tape in fast forwarding in the condition, where the reproducing head is under non-contacting state, by causing the head to be allowed to contact with a tape when a counted value of rotational frequency of a reel shaft becomes coincident with a set value and by heading a position signal. CONSTITUTION:When a signal in the desired position is inputted from a reference position, a control circuit 8 generates setting position information from the position information a certain amount before the head serching position and stores it in a memory 11. By reproduction instructions of a tape the control circuit 8 clears a counter 7, separates a reproducing head 9 from a tape through a head drive mechanism 10 and fast winds a tape through a motor 3. The rotation of a reel 1 is detected by a rotary encoder 6 and counted by the counter 7. The control circuit 8 causes the head 9 to be allowed to contact with a tape when a set value of the memory 11 becomes coincident with the counted value and to reproduction-travel steady at the time of detecting a position signal. Thus the head serching with high accuracy and reliability and little abrasion of a reproduction head can be carried out.

Title: Microwave range
Inventor: ARAMAKI YOSHIHIRO
IPC: F24C1/02
Filed: 1986-02-22
Abstract: PURPOSE:To make a simplified control circuit, reduce the number of relays used and enable a price of the unit to be less expensive by a method wherein a convection motor and a damper motor are controlled by a common relay. CONSTITUTION:When a signal of convection cooking operation is outputted through a control unit CU, a convection motor CM, a heater element HE and a fan motor FM are operated. At this time, a damper is in its opened condition, the damper motor DM is supplied with a voltage through a first fixed contact point A and a movable contact point C of a switch S4 to drive the damper motor so as to operate the damper to its closed condition. When the damper is closed, the switch S4 is changed over by a cam 1 and the motor DM is stopped. Upon completion of the cooking operation, a common contact point (c) of the relay RY7 is connected to a normal-closed contact point (b). Since an electrical current is supplied to the damper motor DM through the second fixed contact point and a movable contact point C of a switch S4, the damper motor DM is operated to drive the damper to its opened condition. The damper motor DM is stopped through operation of the cam 1 and the switch S4.

Title: Laser breakdown analyzing apparatus
Inventor: NISHITARUMI TAKESHI
IPC: G01N15/14
Filed: 1990-02-19
Abstract: PURPOSE:To exactly detect the acoustic waves generated by a breakdown by converging a laser always to a specified position regardless of the refractive index of an analyzing sample. CONSTITUTION:A YAG laser beam 2 transmits a beam sampler 3 and an optical window 4 and is converged by a reflecting mirror 7 of a concave spherical shape to the central part of a sample cell 5. The measuring sample is introduced from an introducing port 9 and is discharged from a discharge port 8. A piezoelectric element 6 detects the acoustic waves generated by the laser breakdown and transmits these waves to a signal processing section 11. A photodetector 10 transmits a reference signal to the signal processing section 11 upon receiving the laser beam 2' reflected by a beam sampler 3. The signal processing section 11 transmits only the acoustic signal synchronized with the reference signal to a control section 12. The control section 12 calculates the particle density and grain size distribution in the sample by this acoustic signal. Then, the reflecting mirror 7 of the concave spherical shape converges the laser always to the specified position regardless of the refractive index of the sample. The piezoelectric element 6 exactly detects the acoustic waves by the breakdown and the measurement with less errors is made.

Title: Magnetic tape device
Inventor: MORI YOSHIAKI
IPC: G11B15/087
Filed: 1995-02-27
Abstract: PURPOSE: To accurately search and position a block by correcting target sector information to a value closer to the BOT when a prescribed value from a target value is too close to a target block. CONSTITUTION: A target sector correcting section 20 first judges whether or not the positioning of a target block is to a position near a turning point by comparing a lap marked sector number and target sector number. When the target sector number falls within a specific range before and after the lap marked sector number, the target sector number is corrected to a value closer to the BOT. Therefore, such inconvenience that the target sector number is positioned to a part where the data on the terminating end side of a tape are not written or positioned too close to the target block can be evaded.

Abstract: PROBLEM TO BE SOLVED: To provide a detection means capable of automatically changing mode setting without manually performing a key input operation normally, preferentially performing mode change by the key input operation especially when it is required, and preventing erroneous detection due to a ped inside a room and voice from the outside or the like. SOLUTION: An optical sensor 2 detects illuminance inside the room and outputs illuminance detection signals. A presence/absence operating mode setting part 3 receives the illuminance detection signals, judges that the person is present in the room and sets a presence mode when the illuminance inside the room is more than a reference value, judges that the person is not present in the room and sets an absence mode when it is not, sets the presence mode when the setting input of the presence mode is performed from an operation key input part 1 even while the absence mode is set, sets the absence mode when the setting input of the absence mode is performed from the operation key input part 1 even while the presence mode is set and outputs presence/ absence mode setting signals.  An optical detection sensitivity adjustment part 4 adjusts the optical detection sensitivity of the optical sensor 2 by sensitivity instruction input signals from the operation key input part 1.

Title: Rolled paper accelerating method for rotary press printing machine
Inventor: TOSHIFUJI TAKAHIDE
IPC: B65H23/185
Filed: 1995-02-27
Abstract: PURPOSE: To slowly accelerate a rolled paper at the time of starting and to slowly decelerate it just before attaining low speed by varying the ratio of a full acceleration term T1 to a constant acceleration term T2 within a specified range to form an optional speed curve, and controlling the speed of a motor according to a signal issued on comparison between the above speed curve and an actual reel speed. CONSTITUTION: The speed of a reel 8 obtained from a tachogenerator 2 is compared with a value obtained by integrating a preformed set acceleration curve 10 through an integrater 3 by a controller 4. A difference between the above items is transmitted as a fluctuation in the control current of a motor 1 by a servomotor 5 for controlling the speed of the reel. The ratio of a full acceleration term T1 to a constant acceleration term T2 is therefore varied within the range of T1 >T2 to form an optional speed curve having a smooth S-shape, and the speed of the motor 1 is controlled on the signal obtained by comparing the above speed curve with the actual speed of the reel 8, and the optional smooth control of acceleration and deceleration can thereby be carried out.

Title: Clock recovery circuit
Inventor: KONDO NORIAKI
IPC: H04L7/033
Filed: 1986-02-24
Abstract: PURPOSE:To stabilize a recovered clock signal by using an out of synchronism preventing circuit so as to attain phase control forcibly by means of a counter content when a timing signal is not extracted with the certain probability. CONSTITUTION:When an input signal (a) is fed to an input terminal 1, a timing extraction circuit 2 extracts a timing signal 2a from only a signal having a small inter-bit interference. When the extracted timing signal 2a is inputted to a phase comparator 13, the phase between the timing signal 2a and an output signal 18a of a frequency divider 18 is compared, the output signal 18a of the frequency divider 18 is fed back to the phase comparator 13 to synchronize itself with the input signal (a). If the frequency of generation of a specific pattern whose timing is to be extracted is decreased and synchronizing step-out preventing circuit 15 does not apply phase control for a prescribed time, the phase control is applied forcibly. Thus, the stable phase synchronization operation is attained.
