Title: Dust collecting apparatus
Inventor: NISHIDE HIROYUKI
IPC: B01D46/26
Filed: 1983-05-04
Abstract: PURPOSE:To provide the titled dust collecting apparatus of which the machine material is brought to long life and easily regenerated, constituted of such a mechanism that a part of the floating substance in the revolving fluid in a dust removing chamber is caught by a barrier plate and the remainder is filtered by the filter material of a rotary cylinder while the flexible filter material is floated by the reverse rotation of the cylinder to clean the same. CONSTITUTION:The fluid to be purified sucked by a suction fan 13 is flowed into a dust removing chamber 1 from a suction port 14 in a revolving state and the relatively heavy floated substance therein is centrifugally caught by a barrier plate 15. The remaining floating substance is filtered by the filter material 9 and the filtering orifices 8 provided to a rotary cylinder 6. The cleaning of the filtering surface 5 is performed by the floating of the flexible filter material 9 by the reverse air stream generated by the reverse rotation of the cylinder 6. Because the relatively heavy floating substance is preliminarily removed to prevent the damage of the filtering surface 5 which is, in turn, cleaned by extremely short-time reverse rotation, the life of the apparatus is extended and is always kept in excellent state.

IPC: G03G15/00
Filed: 1989-03-30
Abstract: PURPOSE:To make a drive unit smaller in size and lighter in weight by forming at least a guide and an elevator box of an elevator unit with lightweight plastics. CONSTITUTION:An elevator box 20 and a second guide 28 both are formed with light plastics for lightweightiness, and since lifting force for the elevator box 20 is one a half in the past, drive torque of a second motor 30 also reduces by half as compared with the conventional one, and this fact makes a sorting device possible for the promotion of small size and lightweightiness consequently. In addition, since the elevator box 20 inclusive of a mounting part is formed with an integral molding of plastic, there is no trouble for forming as compared with plate working in the past, and that there is unnecessary to screw plural numbers of parts, so that forming time and parts reduction, say, cost is reduced consequently, thus assembling accuracy in the elevator box 20 can be uniformized as well.

Abstract: PURPOSE:To mount easily a RAM in a controller by providing a discriminating circuit and a transfer direction determining circuit which judge and determine the transfer direction of data and a read/write circuit which transfers data according to the determination. CONSTITUTION:A control signal regarding the direction of data transfer from a host system 4 is inputted to the read/write discriminating circuit 6 of the controller 2. The circuit 6 when discriminating data transfer from an IC3 to the RAM5 informs the data transfer direction determining circuit 7 of that, which decides that the request to the RAM5 is a write instruction. Consequently, the data transfer direction is determined and sent to the read/write circuit 8. Consequently, data read from a driver 1 by the IC3 is written in the RAM5. Then, when a request for transfer from the system 4 is generated, data from the RAM5 is transferred to the system 4 according to the decision results of the circuits 6 and 7.

Title: Projection screen
Inventor: KANZAWA SADAOMI
IPC: G03B21/62
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To improve the image quality of a rear-projection type projection television. SOLUTION: The projection screen 10 is constituted of a λ/4 plate 50, a screen 60, the λ/4 plate 70 and S polarizing film 80. The image light is constituted of only P wave. The image light is converted into P+λ/4 wave by being passed through the λ/4 plate 50, and is passed through the screen 60. Light passed through the screen is converted by the λ/4 plate 70 again so as to be changed to P+λ/4+λ/4 wave. Thus, it is converted into the S wave, and is passed through the S wave polarizing film 80. In the case that external light hits the screen 60 and is reflected, it is reciprocatively polarized and converted twice by the λ/4 plate 70, and is absorbed by the S wave polarizing film 80, so that the deterioration of the image quality caused by the external light is eliminated.

Title: Phase control circuit
Inventor: OGAWA HIROSHI
IPC: G11B20/10
Filed: 1987-03-31
Abstract: PURPOSE:To always attain excellent data read by recording a sample signal by the same recording means as the recording means recording signals between synchronizing signals recorded periodically onto a prescribed location of a recording medium and controlling the phase of a data readout clock signal whose phase is locked by the synchronizing signal based on the sample signal. CONSTITUTION:The phase difference caused depending on the difference from the recording conditions is adjusted automatically based on the signal recorded at recording onto a data readout signal correction area 3h as a sample signal. For example, if the phase of the correction area 3h is deviated, the delay quantity of a delay line 20 is corrected by the detection of level difference by an operational amplifier 19 and the phase of the clock signal is adjusted so as to read the recording signal on the correction area 3h in an excellent way. Then a data recorded on a data area 2b in the same sector in succession to the correction area 3h is recorded by the same recorder as that for the correction area 3h under the same condition, then the signal is read in the optimum state by the clock signal whose phase is adjusted.

Abstract: PURPOSE:To prevent over temperature of the resistor of a fixing device and its breakage by stopping feed to the resistor according to the pulse energizing cycle and pulse energizing time. CONSTITUTION:An AC input is rectified D1 and smoothed C1. The output signal of a pulse signal generating device 3 is inputted to the photocoupler Q3 in a power source 2 for a fixing device. According to the signal, a drive circuit Q1 drives an energizing control switching element Q2 to the heating resistor (a) of a heater 1. The device 3 controls the feed to the resistor (a) by changing the pulse signal according to the output value of a thermister 5 arranged in the vicinity of the heater 1. When the pulse energizing is executed, an average current I flowing to the resistor (a) is proportional to the ratio of the energizing cycle and energizing time. When pulse duty ratio increases, a fuse FU 1 interrupts a feeding path.
