Title: Synchronizing signal generating system
Inventor: FUKUDA SHINJI
IPC: H04L7/033
Filed: 1984-10-24
Abstract: PURPOSE:To generate automatically a synchronizing signal required at a reception side to decode a data from the transmission side by transmitting a bit rate setting signal having a frequency corresponding to the bit rate of a data transmitted before the start of transmission of data from the transmission side. CONSTITUTION:The transmission side 1 transmits the bit rate set signal having a frequency corresponding to the bit rate of the transmitted data ahead the transmission of data at a reception side 2. The bit rate set signal is fed to a processing section 3 and a detection circuit 4, and the detection circuit 4 outputs a pulse signal at the leading and trailing. The phase locked loop (PLL) inputting the output signal of the detection circuit 4 is constituted by a phase comparator 5, a low pass filter 6, a voltage controlled oscillator 7 and a programmable divider 8. The frequency division ratio of the programmable divider is controlled by a control means so that the output signal of the voltage controlled oscillator has a frequency corresponding to the bit rate. Thus, the PLL is locked by using the bit rate set signal and the output signal of the programmable divider is used as the synchronizing signal of the reception side.

Filed: 1987-09-07
Abstract: PURPOSE:To facilitate to reduce the scale of a circuit without putting a focus error signal into disorder by switching the reproduction level of a preamplifier when a device is switched from a reproduction mode into recording and erasure modes. CONSTITUTION:When the signal of an optical disk is reproduced, switches 7, 8 are operated so as to turn OFF, and when the signal is recorded or erased on or from the optical disk, the switches 7, 8 are operated so as to turn ON. Thus, a current-voltage conversion load resistance of each preamplifier 21, 22 is divided into two lines shown by 3, 4; 5, 6 respectively, and the switches 7, 8 are provided in parallel with one of them, i.e., 4, 6, and the current-voltage conversion load resistance is changed by turning them off at the time of reproducing a signal, and turning them on at the time of recording and erasing the signal. Thus, the focus error signal comes not to be put into the disorder, and in addition, a variable gain circuit comes to be unnecessary.

Title: Coordinate reader
Inventor: OHASHI TSUTOMU
IPC: G06F3/03
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To realize a coordinate reader capable of reading the precise position coordinates of a coordinate inputting means though the output level of an alternate magnetic field generated from the coordinate inputting means is lowered. SOLUTION: When the coils of the same detected value (d) exist among detected values detected by scanning an X-coil (S314: Yes), the CPU of this coordinate reader scraps a position coordinate table stored in a work area and reloads the position coordinate table to make it correspond to a pen attribute (S316). Continually, the CPU calculates the ratio (r) of the value (d) to a reference value (g) (S318) and multiplies (r) by each DIFF showing the voltage difference of the reloaded position coordinate table (S320). Thus, the position coordinate table can be corrected according to the deterioration of the output level of the alternate magnetic field of a coordinate inputting means. Then, the CPU calculates X-coordinates by using the corrected position coordinate table (S330).

Title: Pellet molding disk of compost pelletizer
Inventor: INOUE SATOSHI
IPC: B01J2/20
Filed: 1994-08-25
Abstract: PURPOSE: To obtain compost pellets having a relatively large surface area by forming the die hole shape of the molding disk of a compost pelletizer to a rugged polygonal shape. CONSTITUTION: The die hole 6 of the molding disk 5 of the compost pelletizer which compresses a kneaded compost material, solidifies the material to a pellet form and discharges pellets from the die hole 6 is formed to the rugged polygonal shape. As a result, the compost pellets have the surface area relatively large with respect to the volume and, therefore, anaerobic bacteria decrease, by which malodors are drastically relieved. More preferably, the die hole 6 formed by perforating through the molding disk 5 is composed larger in the area of the discharge side opening 6b of the compost material than the area of the pressure receiving side opening 6a. As a result, the initially molded pellets extruded from the die hole are bulged in the diameter-expanding part of the die hole, by which the excess curing of the pellets is suppressed and the extrusion resistance of a screw is lowered.

IPC: G01M15/04
Filed: 1984-10-26
Abstract: PURPOSE:To self-diagnose positively and precisely acting condition of a crank- angle sensor, by calculating a ratio of change of frequency of a detecting signal from the crank-angle sensor and judging an abnormality by its magnitude. CONSTITUTION:A crank-angle sensor A generates a detecting signal P by a pulse every time when an engine crankshaft passes the reference rotational position. A detecting signal frequency counting means C counts period T1 of the signal P per every signal P. Next, a ratio of change calculating means c divides the currently counted period T1 by the previously detected period T0. By this arrangement, the ratio of change of period of the signal P is calculated per each signal P. Later a judging means self-diagnoses acting condition of the sensor A basing on the calculated ratio of change.
