Title: Fixing member of workpiece to be ground
Inventor: WATANABE TAKASHI
IPC: B24B41/06
Filed: 1988-01-22
Abstract: PURPOSE:To make it possible to dress a grinding tool and grind a workpiece simultaneously by forming a member to fix the workpiece with vitreous material comprising fine grains of material capable of becoming abrasive grains included and giving a grinding tool dressing function to this fixing member. CONSTITUTION:Base material of a fixing member(compound material) 2 is made of fine vitreous material). This prevents melted wax 3 from soaking into the fixing member 2, which allows the fixing member 2 to readily adhere to a workpiece(made of ceramics) 4 by means of wax 3. The fine grains composed of alumina and silicon carbide capable of becoming abrasive grains included in the base material work as a dresser on grinding tools made of diamond or CBN when being ground together with the workpiece 4.

Filed: 1986-01-24
Abstract: PURPOSE:To extract only a defective part with good accuracy by providing a means for renewing a reference threshold and a means for comparing the reference threshold with an original signal and outputting a binarization signal. CONSTITUTION:If the value at the time t1 is a pole, the reference threshold held by a holding part 9 at the present time t1 and f(t1+DELTAts) are compared by subtraction part 10, a comparison part 12, and the difference therebetween is below the value of a threshold generating means 11, f(t1+DELTAts) of an output of a DELTAts delay part 8 is newly held by the holding part 9. With respect to the value f(t1+DELTAts) held by the holding part 9, if the value of a threshold generating part 15 is considered to be (p) and the binarization signal to be I(t), when an interval t1+DELTAts<=t<t2+DELTAts and f(t1+DELTAts)-f(t)<p, I(t)=0, and when f(t1+DELTAts)-f(t)>=p, I(t)=1 and the binarization signal is obtained from a comparison part 6. The processing above mentioned is carried out on all the intervals, a floating binarization output is obtained. Thereby, only the defective part can be extracted in a real time and with the good accuracy.

Title: Blower driven by electric motor
Inventor: FUKUMOTO MASAMI
IPC: F04D29/66
Filed: 1979-02-07
Abstract: PURPOSE: To reduce noise developed by air flow collision by providing a notch in the peripheral end of a fan which disturbs the state of air flow at the discharge and diffuses thereby the energy with which the air pulses collide with the tongue.  
     CONSTITUTION: The fan 4 consists of three parts, the front shroud 8, vane 9, and rear shroud 10. A rectangular notch 13 is made near the outlet 11 of the vane 9 as shown in the figure, and at the same time the front shroud 8 is mounted along the upper curved face of the vane 9 to form a concave face that faces the inlet 12. By this configuration the state of air flow at the discharge near the fan outlet becomes not uniform, and, as shown in the figure, the air flow develops into air pulses that are nearly its three divisions and collides with the tongue. The energy at the time of the collision is, therefore, diffused and loudness of the sound that was developed by air collision is reduced.

IPC: B41J7/48
Filed: 1981-02-02
Abstract: PURPOSE: To enable an electromagnet to posses a plural number of columns and to provide an  inexpensive printer which reduces vibration and noise, and performs a high-reliable selecting  operation, by a method wherein a selection is performed by turning a type wheel shaft a plural  number of times, and a selecting claw is driven at intervals of a plural number of columns  by a selecting claw driving means.   
     CONSTITUTION: A type wheel shaft 1 starts to turn in a direction of an arrow mark d, but a  type wheel 2b for even-numbered column is checked by a selecting claw 4d, which results in  preventing it from rotating. A type wheel 2a for odd-numbered column turns togetherwith a  shaft 1 through a friction force. When a desired type 201 reaches right before a printing position 9, an electromagnet 5 is energized to turn the selecting claw 4a in a direction of an arrow (a), and the claw 4a is in gear with a gear part 202 in a type wheel 2a, which results in bringing the the wheel 2a into a stop. A projection part 301 on a spring 3, set to the type wheel 2b,  engages a recess 101 in the shaft 1 at a second turning time. A selecting claw driving means 6  is further in a direction of an arrow mark b and is caused to return to its original position  after it is brought to a state shown in a dashed line. Then, the wheel 2b for even-numbered  column starts to rotate in synchronism with a spring 3. A subsequent selecting motion is conducted in the perfectly same manner as that at a selecting time at the first turning time of the  shaft 1.

Title: Manufacturing method of plate for lead storge battery
Inventor: KOMAKI AKIO
IPC: H01M4/22
Filed: 1983-01-31
Abstract: PURPOSE:To improve formation efficiency and reduce formation electrification levels by applying on-off pulse current through fixed current at the initial stage of the formation of a non-formation plate. CONSTITUTION:When the formation of a non-formation plate is performed, on- off pulse current through fixed current is applied at the initial stage of the formation. For example, a non-formation plate for a positive electrode and a non- formation plate for a negative electrode are arranged in a formation container. On-off pulse current is applied every minutes simultaneously with the start of electrification through fixed current up to the theoretical time of 100% of formation efficiency. Subsequently, continuous current is applied through fixed current in the same way. After formation is completed, a battery is assembled and specified intial charge is performed. As a result, after the formation in the vicinity of a grid frame is completed, the inner part of a non-formation active material layer is prevented from advancing toward the surface of the non-formation plate in a branch form and formation efficiency can be improved and then all formation electricity levels can be reduced.
