Title: Apparatus for controlling amount of return sludge
Inventor: OTA MINORU
IPC: C02F3/12
Filed: 1989-09-28
Abstract: PURPOSE:To prevent the accumulation of sludge in return piping by keeping the min. amount of the return sludge from a final sedimentation basin to an aeration tank by a keeping means when the inflow amount of sewage to the aeration tank is extremely lowered. CONSTITUTION:When a sewage inflow amount 8 is extremely lowered to reach a dangerous lower limit value generating the accumulation of sludge in return piping 5, a lower limit alarm circuit 15 is operated and a change-over piece C is changed over to a b-terminal to be connected to a min. flow rate output circuit 16 and the min. amount generating no accumulation of sludge in the return piping 5 is kept. When the sewage inflow amount 8 reaches the lower limit value, the change-over piece C is changed-over to an a-terminal by the lower limit alarm circuit 15. As mentioned above, since a keeping means keeping the min. amount of return sludge 10 to a degree not generating the accumulation of sludge in the return piping 5 of return sludge is mounted, even when the sewage inflow amount 8 to an aeration tank 2 becomes extremely little, it is prevented that the return sludge amount from a final sedimentation basin 13 to the aeration tank 2 becomes extremely little and sludge is not accumulated in the return piping 5.

Title: Detecting device for rotational angle of resolver
Inventor: KUMAMOTO SHUICHI
IPC: G01P3/44
Filed: 1987-10-07
Abstract: PURPOSE:To correct a phase shift caused by a variation of an output impedance of a resolver by applying an offset voltage being proportional to a rotational angle frequency of the resolver to an input of a PI controller of a phase locking circuit. CONSTITUTION:A resolver 5 attached to a rotating body is excited by an exciting device 30 based on a reference frequency, a voltage signal corresponding to an output phase signal of the resolver 5 is converted to a frequency signal by a phase locking circuit 40, and a two-phase signal corresponding thereto is brought to feedback control against the output phase signal of the resolver 5. A speed signal demodulating circuit 50 adds an offset compensating voltage signal to a voltage signal corresponding to the frequency signal of the phase locking circuit 40 and outputs a speed signal of the rotating body. An adder 17 adds a reference frequency signal of the exciting device 30 and the output frequency signal of the phase locking circuit 40. Subsequently, by feeding back a voltage corresponding to the speed signal to the voltage signal corresponding to the output phase signal of the resolver 5, a rotational angle being free from a phase shift is detected.

IPC: B41J2/135
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To produce a nozzle plate having a superior ink drip discharging performance by uniforming the diameters of nozzle holes. SOLUTION: A holding material is introduced via a gate portion 104 with dummy pins 110 being arranged in alignment on sides of each nozzle pin 105 that is in turn arranged in alignment in a molding area of a mold.

Title: Controller of catalyst with electric heater
Inventor: WATAYA SEISHI
IPC: F01N3/20
Filed: 1991-10-01
Abstract: PURPOSE:To prevent that an engine cannot be started due to reduction of battery capacity by detecting temperature of engine and inhibiting conductivity to an electric heater in a catalyst section when the temperature is below the predetermined temperature. CONSTITUTION:A temperature sensor 16 is provided in an engine 1 to detect temperature of cooling water or engine oil. When a key switch 13 is on, a catalyst control section 14a reads output of the temperature sensor 16. When it is higher than the previously set temperature, electricity is conducted to an electric heater 9 in a catalyst section 8 from a battery 11, and when it is lower than the set temperature, electricity is not conducted. Thus, when temperature of engine is below the predetermined temperature, conductivity to the heater 9 is stopped to prevent that engine cannnot be started due to reduction of battery capacity when temperature of engine is low.

The obtained mixture is inoculated with a microorganism such as high temperature bacterium or medium temperature bacterium and allowed to ferment for about 4-5 weeks to obtain a fertilizer. The liquid component B is introduced in a packed filter tank 3 packed with e.g. zeolite of 2-5mm in particle diameter. The filtrate is the primary treated liquid C in which e.g. SS is reduced.  The primary treated liquid C is placed in a purification treatment tank 4 packed with small wooden pieces and air is intermittently introduced under stirring to digest and decompose the organic matter by microorganisms. BOD of the liquid is decreased, below several tens ppm and the secondary treated liquid D is obtained. The secondary treated liquid D is further subjected to an oxidative bactericidal decoloration treatment under the introduction of ozone gas from an ozone generator 5 to obtain the tertiary treated liquid E. The liquid E is recycled as waste water.

Title: Diamond tool
Inventor: IGAWA NAOYA
IPC: C30B29/04
Filed: 1987-10-09
Abstract: PURPOSE:To improve the cutting performance of the tool in the caption by obtaining light and dark patterns appearing within a diamond monocrystal due to the difference in luminous efficiency with the aid of a scanning electron microscope so as to form a cutting edge at a position located in an area except for the border area between an approximately uniform luminous area and a non-luminous area. CONSTITUTION:In order to carry out the submicron analysis of a dodecahedral diamond monocrystal, a cathodeluminescence detector is built in a scanning electron microscope, and an elliptic mirror is used to collect the light so as to observe light and dark patterns which are concentrically formed along the growing direction of the crystal. If there is an outstanding difference between the light and the darkness in a cutting edge, the edge is frequently broken in the border area when its cutting is carried out. Therefore, when the cutting edge is formed, it is formed in an approximately uniform luminous are with uniform defect density, or a non-luminous area except for the border area where an outstanding difference between the light and darkness is found. Thus, an extremely reliable cutting edge can be formed so as to improve its cutting performance.
