Filed: 1990-01-12
Abstract: PURPOSE:To prevent the beam shape of a +1st diffracted light from being deformed by installing a diffracting element at a position where an angle to be formed by the main beam of a 0-th diffracted light to be transmitted through the diffracting element and the main beam of the +1st diffracted light to be diffracted by the diffracting element makes an equally two dividing line direction coincident with the normal direction of a diffracting element plane. CONSTITUTION:A diffracting element 1 is obliquely installed so that the equally two dividing line direction of an angle 2theta to be formed by a main beam 5 of a 0-th diffracted light 4 to be transmitted through the diffracting element 1 and a main beam 8 of a +1st diffracted light 7 to be diffracted by the diffracting element 1 can be coincident with a normal 6 direction of the diffracting element 1 plane. Therefore, a reproducing light 2 obtains the same shape in the case of observing a spot to be formed on the diffracting element 1 from the main beam 5 direction (an arrow A direction) of the 0-th diffracted light 4 and from the main beam 8 direction (an arrow B direction) of the +1st diffracted light 7. Thus, the beam shape of the +1st diffracted light is not deformed but made same as the beam shapes of the reproducing beam and the 0-th diffracted light.

Title: Reading mechanism for magnetic stripe data on bankbook
Inventor: TANAKA HIDEYO
IPC: G06Q40/02
Filed: 1985-01-18
Abstract: PURPOSE:To read the magnetic stripe data on a bankbook with no retry by reading the information recorded with a phase difference as if it ware apparently recorded in a correct way, detecting the phase difference between tracks and correcting it when the information recorded with a phase deviation is reproduced. CONSTITUTION:A bankbook 1 is shifted toward an arrow head by rolls 5. The timing signal needed for synchronization is recorded to a magnetic stripe 2 in addition to other ordinary infomation required. The polarity of a track '1' is inverted with the data 1 and the polarity of a track '0' is inverted with the data 0 respectively. The reading waveforms of tracks '1' and '0' are converted into square waves by a waveform shaping circuit 6. Then the data on the track '0' is delayed by the fixed period of time by a delay circuit 7. The data on the track '1' is delayed by an amount equal to the time difference T obtained between both tracks when a start code is detected by a decoder 8 which detects the start code recorded after the timing signal. Thus the phase relation between the data on the track '1' delayed by a data delay circuit 10 and the data on the track '0' is equal to that obtained from a correct recording action.

IPC: G01K7/22
Filed: 1996-01-17
Abstract: PROBLEM TO BE SOLVED: To prevent the possibility of false detection from occurring by arbitrarily setting the characteristics of a PTC thermistor. SOLUTION: In a PTC thermister 2 used in a temperature sensor, the disk shape is halved, and the respective divided parts are formed of sintered bodies 2a and 2b having the different preset temperatures. At this time, an initial resistance value R0 at an initial temperature T0 in the sintered body 2a is higher than an initial resistance value R0 ' at the initial temperature T0 in the sintered body 2b. In the meantime, a detected resistance value R1 at a detecting temperature T1 in the sintered body 2a is lower than a detected resistance value R1 ' at the detecting temperature T1 in the sintered body 2b.  Therefore, the characteristics obtained in the PTC thermistor 2, wherein the sintered bodies are connected in parallel are as follows: the initial resistance value R0 " at the time of the initial temperature T0 is approximately equal to the initial resistance value R0 ' in the sintered body 2b; a detected resistance value R1 " at the time of the detecting temperature T1 is approximately equal to the detected resistance value R1 in the sintered body 2a; and the V-shaped characteristic is improved.

Abstract: PURPOSE:To enhance the backwashing effect of a filter element, by forming the filter element by stacking plates each having recessed and protruded parts provided to the upper and lower surfaces thereof while providing an element guide capable of enlarging the gaps of the filter element. CONSTITUTION:A fluid containing solid foreign matters is flowed into a cylindrical filter element 5a from the outer (or inner) side thereof and passed through the gaps between laminated flat discs of the element 5a to be discharged to the inner (or outer) side of the element 5a. Foreign matters are collected at the inlet of the gaps of the flat discs. Each gap between flat discs forms a certain flow path by slightly shifting the directionality of processed grooves provided to the upper and lower surfaces of said flat disc. When foreign matters are accumulated on the element, an element guide 9 is moved from a usual position 9c to a position 9b. By this mechanism, the distance between the discs is enlarged and foreign matters tightly accumulated in the interior can be easily backwashed.
