Title: Induction motor speed control
Inventor: OKUYAMA TOSHIAKI
IPC: H02P21/24
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To prevent generation of torque shortage even in a zero-speed area without being influenced by a speed estimation error, by controlling d-axis current to a normal value or higher and computing a frequency command value based on a speed command value in place of a speed estimation value, if the speed command value is a prescribed value or lower. SOLUTION: To control motor current iq, id according to a q-axis current command value iq* and a d-axis current command id** from a speed controller 5, d-axis and q-axis voltage reference values Vd*, Vq* are computed based on the current command values id**, iq* and a frequency command ω1** in a voltage computing device 13. In a zero-speed area, a torque decrease is apt to occur due to various causes, therefore, a speed command value ωr* is selected to be outputted in place of an ω1* at ordinary time by a switch 9, and Δsd is added to a reference value id* at ordinary time by a q-axis current command device 11 to control the id so as to strengthen it. It is thus possible to prevent generation of torque shortage even in a zero-speed area.

Title: Oil-water separator
Inventor: TANAKA KIICHI
IPC: B01D17/04
Filed: 1981-11-05
Abstract: PURPOSE:To make the construction of a titled device simple and inexpensive by forming plural oil-water separating chambers having level differences and an oil storage tank between cylindrical nets provided freely attachably and detachably to a staircase-like support concentrically at intervals of plural sheets and admitting oil-contg. waste water therein. CONSTITUTION:The oils in oil-contg. waste water float on the liquid surface on  account of difference in specific gravity between water and oil. Since nets 3-5 made of silicone resins or the like are cylindrical, the oils flow together with some water into the 1st separating chamber 6 lower than the liquid surface efficiently from the entire circumference of 360 deg. through the 1st net 3. Thereafter, the oils pass through the 2nd net and flow into the 2nd separating chamber 7 having a level difference from the 1st chamber. In this time, the net 4 has finer meshes than the net 3; therefore, said net permits the transmission of most of the oils alone. Finally, the oils pass through the 3rd net 5 and flow into an oil storage tank 8. The oils stored in the tank 8 are recovered through a discharge port 12 by opening a valve 11.

Title: Water repellent treatment of ceramic article
Inventor: MIZUNO HARUYUKI
IPC: C04B41/52
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To solve the problem that it is difficult to form an effective water repellent layer on the surface of a sanitation fixture because of a smaller amt. of silanol groups as compared with glass, etc. SOLUTION: The surface of a glazed ceramic article such as a sanitation fixture is subjected to water repellent treatment after spraying with water or steam. Since silanol groups on the surface of the article are increased by the spraying, a water repellent becomes liable to bond and the formation of a water repellent layer is ensured. The spraying may be carried out under <=10 atm pressure. Silanol groups may be increased by increasing the surface area of the glazed ceramic article by chemical etching. A precoating layer having high reactivity with the water repellent may be formed by fixing an alkoxide on the surface of the article by a sol-gel process.

Filed: 1993-07-16
Abstract: PURPOSE:To realize the detection of exhaust air temperature which makes good precision compatible with responsibility by obtaining exhaust air temperature by simulation based on exhaust air reach temperature which is calculated based on load and speed of an internal combustion engine. CONSTITUTION:An exhaust air temperature computing means 6 computes convergence temperature as exhaust air reach temperature in accordance with engine speed detected by an engine speed detection means 4 and load detected by a load detection means 5. On the other hand, estimated temperature of exhaust air temperature at each instant is stored in an estimated exhaust air temperature storage means 7, and an updated value computing means 8 calculates an updated value which becomes a new estimated exhaust air temperature based on the computed change rate from a difference between the estimated temperature and exhaust air reach temperature. Thus, estimated exhaust air temperature which simulates actual exhaust air temperature with high precision is stored. As a consequence, an increased quantity compensation execution judging means 9 judges that fuel increased quantity compensation should be carried out only when exhaust air temperature of an engine 1 reaches the overheated condition and gives a command of adequate injection quantity from an injection control means 3 to a fuel injection means 2.

Abstract: PURPOSE:To prevent the effect of an interference wave on an FSK demodulation circuit, by providing a comparator comparing an output of a BPF corresponding to each frequency with a threshold value, and interrupting a demodulation comparison circuit when the said level exceeds the threshold value. CONSTITUTION:An FSK modulation signal obtained from a reception circuit 15 passes through two BPFs 3, 4 and inputted to a comparison circuit 11 via envelope detection circuits 7, 8.

Other envlope detection lines 16, 17 are connected to the output of the BPFs 3, 4, and the detected outputs are compared with a threshold value at comparators 20, 21. When either one of the comparators has an output, any of the comparators 7, 8 corresponded is grounded with transistors 26, 27 and the comparison circuit 11 takes this ground level as a comparison circuit and democulates an FSK signal. Thus, the demodulation not affected with interference signals can be performed.

Abstract: PURPOSE:To generally increase efficiency over the wide band area of a low frequency sound while the resonance of an acoustic tube is continuously generated by constituting plural pieces of acoustic tubes having different lengths on the back face of a speaker unit and further providing a shared acoustic tube at an outlet. CONSTITUTION:Partition boards 6a-6h in a cabinet 5 are constituted of two acoustic tubes having different length continuously extended from the back face of a speaker unit 8 and a shared acoustic tube at these outlets. Under a frequency f1 that one wavelength tunes in the longer acoustic tube, the front face sound of the speaker unit 8 is inverted with a sound to be radiated from an opening 7 of the common acoustic tube and a large sound pressure trough is generated. The shorter acoustic tube can be of an arbitrary acoustic characteristic by selecting its length, for example, when a tube length is obtained that a 3/4 wavelength tunes in at f1 so as to offset the sound pressure trough of the longer acoustic tube, the reproducing band of a low sound area can be widely expanded.

Title: Lens focus adjusting mechanism for handy image scanner
Inventor: ISHIKAWA YUKIHIKO
IPC: G06K9/20
Filed: 1988-07-16
Abstract: PURPOSE:To attain sure vertical adjustment and to prevent the movement in the lengthwise direction by fitting a holding jig to both ends of a SELFOC lens, engaging the assembly to a frame, screwing a thread to the holding jig via the frame and interposing a compression spring between the frame and the holding jig. CONSTITUTION:When a screw 4 is turned in the screwing direction, the screw 4 is screwed into the holding jig 7 to move the SELFOC lens 2 upward. Since the slot 7a of the holding jig 7 is engaged with a guide 1b of the frame 1, the SELFOC lens 2 is not moved in the lengthwise direction and the SELFOC lens 2 is moved smoothly. When the screw 4 is turned in the loosening direction, the screw 4 is loosened from the holding jig 7 and the SELFOC lens 2 is moved downward by the force of the compression spring 8 and the self-weight of the SELFOC lens 2. Thus, the SELFOC lens 2 is surely adjusted vertically and the movement in the lengthwise direction is prevented.
