Title: Spindle servo device for rewrite type recording disk player
Inventor: ONIGATA YOSHIO
IPC: G11B19/28
Filed: 1991-11-08
Abstract: PURPOSE:To smoothly and quickly lock in at the time of the start of playing by adjusting the frequency division ratio of a reproducing clock at the time when the operation of a reproducing clock generating means is in the unstable state. CONSTITUTION:The clock component obtained by a BPF 16 is supplied to a PLL circuit 21, and a reproducing clock pulse string as the output is supplied to a clock counter CT 22 as the 1/N1 frequency divider. A phase comparing circuit PC 24 indicates the change of the frequency division ratio in accordance with the positive and negative of the phase difference between a sector synchronous detection pulse and the output pulse of the 22. The PC 28 indicates the change of the frequency division ratio of a CT 23 in accordance with the positive and negative of the phase difference between sector number data and counted value data. A PC 30 sends a signal, whose level corresponds to the phase difference between the output pulse of a decoder 29 and the pulse from a reference signal generating circuit 31, to a subtractor 33. The subtraction output is sent to a spindle motor 35. If the PLL circuit 21 is in the unstable state, count capacities of CTs 22 and 23 are adjusted to adjust the frequency division ratio.

Title: Burner
Inventor: YUKIMURA MASAHIKO
IPC: F23N1/00
Filed: 1987-11-20
Abstract: PURPOSE:To switch over the number of burners to be used in automatic mode and secure a required combustion volume ranging from a small combustion volume to a large combustion volume by setting both the minimum quantity and the maximum quantity of electric current flowing to a governor proportional valve when electric current does not flow to a solenoid valve so that they may exceed the maximum and minimum electric current when the electric current flows to the solenoid valve. CONSTITUTION:A control device 30 controls a combustion fan 12 and a governor proportional valve 23 based on a predetermined combustion volume. A fuel gas is discharged into burners 11a and 11b from nozzles 16a and 16b. The quantity of gas is proportional to the electric current flowing to the governor proportional valve 23. The electric current flows in a range of diversified current values, depending on the opened and closed status of a switch over solenoid valve 24. When only the burner 11b performs a small amount of combustion, the switch over solenoid valve 24 is in closed status. Under this condition, it is so set that the electric current may be smaller than the minimum and maximum current values flowing to the governor proportional valve 23 when the two burners carry out combustion operation even when the gas pressure supplied to the nozzle 16b is increased. It is, therefore, possible to control the pressure at a low value and reduce the quantity of supply as well. The gas is mixed with the air and burnt by a combustion fan 12, thereby producing a predetermined combustion volume.

Abstract: PURPOSE:To automatically prevent the outflow of a filter medium by providing a backwashing water discharge pipe at the upper part of a contact tank contg. a biological filter bed and in the vicinity of the surface layer of the filter bed. CONSTITUTION:When the biological filter bed 3 in the contact tank 1 is washed, the valve 7 of the treated water discharge pipe 6 provided at the lower part of the tank 1 and the valve 11a of the backwashing water discharge pipe 10a provided at the upper part are firstly closed. Backwashing water is then introduced into the tank 1 from the backwashing water inlet pipe 8 provided at the lower part of the tank 1, hence the filter medium 4 of the filter bed 3 is circulated and washed, and impurities are floated. The valve 9 of the inlet pipe 8 is then closed, and the supply of backwashing water to the tank 1 is stopped. The relatively heavy filter medium settles in this case on the bottom plate 2 in the tank 1. After the filter medium 4 practically settles, the valve 11a of the discharge pipe 10a provided in the vicinity of the surface layer of the filter bed 3 is opened, only the backwashing water and the impurities contained in the backwashing water are discharged from the discharge pipe 10a, and the filter bed 3 is washed without causing the outflow of the filter medium 4.

Title: Graphite intercalation compound and its production
Inventor: TODA MAKI
IPC: C01B31/00
Filed: 1990-11-02
Abstract: PURPOSE:To form a metal halide graphite intercalation compd. excellent in moisture stability by interposing at least PbCl2 among graphite layers having a laminer crystal structure. CONSTITUTION:The graphite intercalation compd. contains at least PbCl2 interposed among graphite layers having a laminer crystal structure. This compd. is produced by the following method. Namely, after the source graphite is mixed with PbCl2 and other metal halides except for PbCl2, the mixture is heated and made to react for a period at least to cause an increase in the weight of the source graphite. The metal halides used with PbCl2 in this process are such compds. which have the function to introduce PbCl2 into graphite layers, and for example, FeCl3, CuCl2, AlCl3, etc. Especially, FeCl3 and CuCl2 are preferable since these compds. produce chlorine gas by the disproportionation of itself so that introduction of chlorine gas from outside is not required. Moreover, the optimum temp. (300-550 deg.C) of these compds. for the reaction with graphite is industrially advantageous.
