Filed: 1987-04-07
Abstract: PURPOSE:To improve the discharging effect of dust by providing an inclined part for spirally guiding a swirling flow which flowed from an inlet into a casting toward a discharge hole, on the end face on the lower part of said casing. CONSTITUTION:Outside air is sucked into a casing 4 from an inlet 5, the air which flows in is accelerated by the inlet 5 and guide plate 18 and flows toward the end face on the lower part of the casing 4 while spirally swirling. During the swirling of air, rough dust contained in the air is pressed against the inner wall face of the casing 4 by centrifugal force and falls toward the end face on the lower part of the casing 4 along the inner wall face due to the action of the swirling flow and the action of gravity. The dust which fallen on the lower part of the casing 4 is introduced into a dust discharging hole 15 along a spiral inclined part 17 provided on the lower part of the casing 4.

Title: Charging method for secondary battery
Inventor: TOYA SHOICHI
IPC: H02J7/04
Filed: 1995-04-11
Abstract: PURPOSE: To realize quick charging without operating a protective circuit by performing pulse discharging such that the battery voltage does not exceed a protective voltage for longer than a set time after performing pulse charging for shorter than the set time, temporarily stopping the charge/discharge operation in order to detect the voltage and stopping the charging operation when the detected voltage reaches a full-charge voltage. CONSTITUTION: A charge control switch SW1 is turned ON and the charging voltage of a battery B is regulated to a second voltage V2 before the battery is charged with a constant current 1-3C for 80sec. The switch SW1 is then turned OFF and a switch SW1 is turned ON to effect pulse discharge for 10msec. Subsequently, the SW2 is turned OFF and the battery voltage is measured upon elapse of 10msec. It is decided whether the battery voltage thus measured reaches a set voltage V1 and if the set voltage V1 is not reached, pulse charging/ discharging and voltage detection are repeated. With such arrangement, the battery can be charged quickly without causing interruption of charging operating owing to function of a protective circuit 1.

Abstract: PURPOSE:To reduce an effect of a writing head to a reading head, by adding a differential signal obtained by differentiating a writing signal with a reading signal and then delivering a peak value signal after wave shaping on the basis of the result of comparison of the above-mentioned added signal with a signal of a prescribed slice level. CONSTITUTION:The reading signal is compensated by means of a differential signal of a writing signal W. A signal obtained by differentiating the signal W through a differentiating circuit 5 is supplied to an adder 7 together with the output signal of an amplifier 3 for addition of these two signals. For the output of the adder 3, i.e., the signal of a terminal P3, the field-through effect can be virtually offset by means of a phase difference between the differential signal and the field-through signal. A comparator 10 compares the output signal of a slice level circuit 8 obtained by a write enable signal with the output signal of the adder 7. The peak value is detected for the output signal of the adder 7 by a peak detecting circuit 9. This peak value signal and the output signal of the comparator 10 are fed to a shaping circuit 11 to obtain a reading output signal R.

Title: Production of light guide
Inventor: GO HISAO
IPC: G02B6/12
Filed: 1987-04-08
Abstract: PURPOSE:To form a light guide symmetrized with a refractive index distribution and to decrease the coupling loss to an optical fiber by forming an MgO film on a substrate and diffusing the MgO into the substrate, then subjecting the same to a proton exchange. CONSTITUTION:The MgO film is formed by vacuum deposition on the substrate 1 (for example, LiNbO3). The MgO is then diffused by a thermal diffusion method into the substrate 1 to form a diffused layer 3. A metal mask 4 is deposited thereon and is formed with an aperture 5 by a lift off method. The aperture 5 is formed to have the plane shape coinciding with the plane shape of the light guide. The Li ions in the substrate 1 are then exchange with the proton (H<+>) to form a proton-introduced region 6A. The mask 4 is thereafter removed to form the light guide 6B. The MgO diffused layer 3 is thus formed on the substrate surface before the proton exchange is executed to symmetrize the refractive index of the light guide 6B. Since the refractive index is symmetrized, the coupling loss of the light guide and the optical fiber is decreased and the effective optical function device is obtd.

Abstract: PURPOSE:To execute an efficient operation of a transmission line, by communicating with a device which becomes other slave station in accordance with status of a fault in case of communication between a master station and a slave station, when transmitting a data between plural digital control devices which are able to become a master station, respectively. CONSTITUTION:A digital control device has a function for controlling a process in accordance with a prescribed control algorithm, and as for these control devices, the master station is changed at a prescribed time or depending on existence of information to be transmitted to other station, in accordance with a prescribed sequence. In case when a control device 3-1 is a master station and is unable to transmit a data even if it communicates with a control device 3-2, the device 3-1 communicates with other station 3-3 and discriminates a fault. In case when it is able to communicate with the station 3-3 in the same data transmission mode, the fault is considered to have been caused by the station 3-2, it transmits a data including a fact that the device 3-2 is faulty, to station which becomes a master station next. In case when a device which has become a master station is faulty, since a fault can be displayed by its station itself, it can be discriminated easily. Also, after a constant time has elapsed, in case said device does not become a master station, it is discriminated as a fault, and an apparatus control of the whole control system becomes easy.
