Title: Frequency hopping type spectrum diffusion radar device
Inventor: MISHIMA TETSUO
IPC: G01S13/524
Filed: 1992-06-30
Abstract: PURPOSE:To achieve coherent processing even without a number of filter banks by transmitting two carriers with different frequencies simultaneously and performing the complex conjugate operation of two base-band signals of reception wave. CONSTITUTION:A carrier generation means 21 generates two carriers where the spacing between two frequencies is maintained to be constant. A transmission/reception means 28 simultaneously transmits two carriers to a target 3 and receives a carrier which is reflected from it. A separation means 31 separates the received carrier into two carriers. A signal generation means 36 mixes (heterodyne detection) two carriers which are separated by the separation means 31 with each reference signal and then converts them to base-band signals and then perform the complex conjugate operation of two base-band signals, thus generating coherent signals. Finally, a coherent signal processing 42 performs coherent processing such as coherent integration, pulse Doppler processing, or traveling target detection processing using the signals.

IPC: B23Q15/00
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To easily conduct radial cut depth control for a rotary tool by inputting pulse signals according to a pulse synchronized with the rotation of a spindle and a cut depth control pulse from a control device to a driving motor for rotating a control shaft.

Title: Synchronizing signal generating circuit
Inventor: UENO KOHEI
IPC: H04N1/06
Filed: 1987-08-05
Abstract: PURPOSE:To prevent the turbulence of a synchronizing due to a malfunction jitter due to noise by constituting a synchronizing signal generating circuit with an internal synchronizing signal forming circuit, a noise component removing circuit and a jitter component removing circuit. CONSTITUTION:In a noise component detecting circuit 10B, only when a noise component included in an input horizontal synchronizing signal does not exist, the input horizontal synchronizing signal is supplied to a jitter component detecting circuit 10C of a rear step as an external synchronizing signal. In the jitter component detecting circuit 10C, whether the jitter component of the input horizontal synchronizing signal is in a prescribed range or not is detected. When it is in the prescribed range, an internal synchronizing signal formed in an internal synchronizing signal forming circuit 10A is used as an output synchronizing signal and when phase shift quantity is over the prescribed range, the phase of the internal synchronizing signal, which is outputted from the internal synchronizing signal forming circuit 10A, is controlled by the external synchronizing signal. Thus, a malfunction due to impulsive noise is avoided and the synchronizing signal generating circuit, which is strong against a jitter, can be obtained.

Title: Transferring and separating device
Inventor: KUNISHI TAKESHI
IPC: G03G15/14
Filed: 1985-09-06
Abstract: PURPOSE:To prevent the retransfer, scattering, and transfer failure of toner at the tail end part of a transfer material by varying the discharging current of each electrifier gradually nearby the tail end of the transfer material. CONSTITUTION:A separating current which allows transfer paper to separate from a photosensitive body securely is supplied from the head of the transfer paper P to, for example, 50mm before the tail end part. A transfer current (a) begins to be increased gradually when the part of 50mm from the tail end of the transfer paper reaches a transfer charger 3 and both AC and DC components or only the DC component of the separating current (b) is decreased in a proper way. Thus, the transfer efficiency of the tail end part of the transfer material is improved greatly to obtain an image having no irregularity in density regardless of variation in the discharging current of each charger without scattering toner nor causing a failure in transfer.

Title: Electron gun for color picture tube
Inventor: SHIMOMA TAKETOSHI
IPC: H01J29/50
Filed: 1984-09-20
Abstract: PURPOSE:To achieve good resolution over the entire area of the picture screen by applying a voltage increasing or decreasing synchronously with the deflection current to the fourth grid of a quadrapotential-type complex electron gun to form a symmetrical lens. CONSTITUTION:The fourth grid 5 consists of three plates. The first plate 8 and the third plate 10 have circular electron-beam holes 11, 12 and 13 and 14, 15 and 18 respectively. The voltage (V2) applied to the first and the third plates 8 and 10 is the same as that applied to the second grid 3. The second plate 9 has lateral rectangular electron beam holes 17, 18 and 19 and a dynamic voltage VD corresponding to the degree of beam deflection is applied to the second plate 9. Because of the above structure, the electron lens forms a symmetrical lens only when deflected. Consequently, it is possible to improve the resolution of the peripheral area of the picture screen without deteriorating the resolution of the central area of the picture screen.

IPC: H04M15/08
Filed: 1986-08-20
Abstract: PURPOSE:To make an operator unnecessary by automatically starting a tariff meter in the receiver side by an exchange in response to the acknowledgement signal sent from a telephone set in the reception side. CONSTITUTION:When a transmitter orally requests a collect call to a receiver during speaking and the receiver acknowledges it, the receiver operates a push dial 11 to send the acknowledgement signal to the exchange. In the exchange, an acknowledgement signal detecting circuit 18 detects this acknowledgement signal to start a receiverside meter starting circuit 20. Then, a preliminarily selected tariff meter in the receiver side is started. Simultaneously, the acknowledgement signal detecting circuit 18 sends a collect call switching signal from a collect call switching signal generating circuit 16 to the telephone in the transmission side. In the telephone set in the transmission side, a signal discriminating circuit 9 detects the collect call switching signal and gives the detection signal to a line connection control circuit 5. The line connection control circuit 5 holds the telephone line in the connected state independently of the signal from a coin detecting circuit 7 or a card detecting circuit 8.
