Title: Duplex surface grinding wheel
Inventor: ISHIGURO TATSUO
IPC: B24D3/00
Filed: 1994-09-26
Abstract: PURPOSE: To prolong the life cycle of a duplex surface grinding wheel by increasing, within a specified range, the percentage of crystallitic sintering aluminum abrasive particles contained in abrasive particles on the grinding plane as closer it gets to the outer circumference of the grinding wheel. CONSTITUTION: The percentage of crystallitic sintering alumimun abrasive particles contained in abrasive particles on the grinding plane 12 of a duplex surface grinding wheel 10 is set higher within the range of 10 to 70 volume percent as it gets closer to its outer circumference portion 16 side. For example, an outer circumference 16 of high peripheral speed and heavy grinding load is composed of 41 volume percent of abrasive particles, 35 volume percent of epoxy resin functioning as a resin bond, and the rest of the volume with pores. 70% of the volume of the abrasive particles is formed of crystallitic sintering aluminum of a submicron size. Although the inner circumference portion 18 is also similarly composed of 41 volume percent of abrasive particles, 35 volume percent of resin bond and the rest with pores, 100% of the abrasive particle volume is formed by a white alundum WA.

Title: Relaxing method for stress concentration for stepped rod
Inventor: UMEMOTO TADAHIRO
IPC: F16B31/06
Filed: 1989-09-05
Abstract: PURPOSE:To improve hydrogen embrittlement of martensite-series metal by covering a corner part liable to generate stress concentration with filler metal. CONSTITUTION:The corner part 8 of a stepped rod (valve stem) 1 is partially cut out. Nextly, filler metal 10 is filled in the cut out part 9. In this case, as the metal used as the filler metal 10 has relatively large work hardening coefficient against martensite series metal, strain is apt to spread on the whole filler metal and overall strain distribution containing the corner part 8 is relatively lenient, and stress concentration of the corner part 8 is relaxed. As the filler metal 10 part has relatively lower hydrogen embrittlement against the martensite series metal and is formed out of metal having large elongation and contraction, generation of fatigue, corrosion cracking, and the like is restrained.

IPC: G11B7/005
Filed: 1991-09-10
Abstract: PURPOSE:To detect the fluctuation of the oscillation wave length of a laser, and to correct a regenerative signal based on it. CONSTITUTION:A light emitted from a laser 12 is collimated by a collimate lens 14, passes through a beam splitter 18, and is condensed on a recording medium 22 by an objective lens 20. The reflected light is reflected by the beam splitter 18, diffracted by a diffraction grating 36, and made incident on a bisecting photodiode 38. When the wave length of the light made incident on the diffraction grating 36 is changed, the angle theta of diffraction is also changed according to the fluctuation, and the position of the beam spot on the dividing photodiode is changed. The fluctuation of the oscillation wave length of the laser 12 is detected as the deviation amount of the beam spot from the output difference of each light receiving area of the bisecting beam photodiode 38, and the regenerative signal is corrected based on it.

Title: Rotational direction detector for motor
Inventor: UDA MITSUYOSHI
IPC: H02K11/00
Filed: 1990-09-01
Abstract: PURPOSE:To obtain a rotational direction detector which can detect the rotational direction of a motor through a simple structure by deciding the rotational direction of a motor comprising a rotary member having two or more hole parts based on a decision which one of first and second detection signals is outputted first. CONSTITUTION:When a motor l rotates in the direction of an arrow A, a second sensor 22 detects a tap hole 3 and provides a detection signal to terminal D of a D flip-flop circuit 31. A first sensor 21 subsequently detects the tap hole 3 and provides a detection signal to terminal CK. Consequently, output terminal Q of the circuit 31 makes a transition from L to H. An H output is provided at the terminal Q in similar sequence so long as the motor l rotates in the arrow A direction. On the contrary, when the motor l rotates in the direction of an arrow B, the first sensor 21 detects the tap hole 3 at first and the second sensor 22 eventually detects the tap hole 3. Consequently, the output terminal Q of the D flip-flop circuit 31 goes L.

Title: Screen input back-up method for terminal equipment
Inventor: OKAZAKI KENICHI
IPC: G06Q40/02
Filed: 1988-09-19
Abstract: PURPOSE:To realize a satisfactory automatic input back-up action even in case an operator forgets an input operation by retrieving a table set at a terminal equipment and storing the prescribed information the field data and inputting data at the CPU side. CONSTITUTION:The field data are essentially required for a keyboard containing an input key and a transmission key which transmits the data supplied by the input key to a CPU as well as for a terminal equipment having a screen to display plural fields. Furthermore a table is added to store the information needed for input of those fields from a host. When an operator performs the key input operation, the due data is sent to the CPU and at the same time the CPU retrieves the table of the terminal equipment. Then the essential field data that can be inputted from the CPU with no key input operation is supplied via the CPU. Thus a satisfactory automatic input back-up action is ensured even in case the operator forgets the input operation. As a result, the countermeasure trouble is saved to the operator's mistakes.

Title: Echo canceling device
Inventor: IGAI KAZUNORI
IPC: H04B3/23
Filed: 1986-09-30
Abstract: PURPOSE:To ensure the follow-up to an echo path even with the characteristic change having a large impulse response length, by combining two echo cancelers of different characteristics. CONSTITUTION:The reception input digital signal received from a reception input terminal 1 and the transmission digital signal received from an A/D converter 2 are supplied to echo cancelers 7 and 8 respectively. The 1st canceler 7 approximates the impulse response of an echo path to the form of a transmission function having a pole for estimation and therefore cancels echoes at a speed several times as high as an echo canceler having the normal impulse response. The 2nd canceler 8 corrects the approximated and estimated error of the canceler 7 and cancels echoes. Thus it is possible to follow even an echo path having a long echo time and the complicated characteristic variation and to cancel echoes.
