Title: Optical element, manufacture of the same, optical pickup and optical recording and reproducing device
Inventor: TAKAHASHI JUNICHI
IPC: G11B7/135
Filed: 2001-04-12
Abstract: PROBLEM TO BE SOLVED: To efficiently and stably perform recording, reproduction, and erasure for a recording medium with a high recording density even though the light incident angle and the distance between a probe and the recording medium fluctuate. SOLUTION: Light cast on an optical element 2 is made incident on the probe 5 through a transparent substrate 4. The light made incident on the probe 5 is repeatedly reflected between tapered surfaces of the probe 5 to converge to a point, and nearfield light 8 is generated in the vicinity of a small opening 9. With the generated nearfield light 8, information is recorded on the recording medium 3 and the information recorded on the recording medium is reproduced or erased. The probe 5 for generating the nearfield light 8 is formed out of tapered surfaces, and the light made incident on the probe 5 is repeatedly reflected between the tapered surfaces and converges to the tip so that the light made incident is effectively utilized.

Title: Dishwasher
Inventor: KAWAGUCHI TOMOYA
IPC: A47L15/42
Filed: 2001-04-13
Abstract: PROBLEM TO BE SOLVED: To provide a dishwasher which is prevented from dropping water adhered on the lower face of the upper lid when the washing chamber is drawn out immediately after pressing the halt key in case dishes are added during washing operation. SOLUTION: This dishwasher is equipped with a lock device to prevent the operating lever operated by a user to latch the door from being released from a latched condition. The lock device is actuated during washing operation.

Title: Fuel property determining device for internal combustion engine
Inventor: MAJIMA YOSHIHIRO
IPC: F02D13/02
Filed: 2001-04-16
Abstract: PROBLEM TO BE SOLVED: To accurately determine fuel properties. SOLUTION: Before an air-fuel ratio sensor installed in an exhaust pipe is activated during the early warming up control of a catalyst, wet quantity decrease control is performed to reduce the wet quantity sticking to the internal wall or the like of an intake port by controlling the opening timing of an intake valve to the delay side from a normal valve opening position. Then, when the air-fuel ratio is activated, the opening timing of the intake valve is gradually returned to the normal valve opening position to complete the wet quantity decrease control and to change over to a state of easily producing the wet. Consequently, the heavier the fuel property is, the more the wet quantity is increased, and the air-fuel ratio of exhaust gas changes in a lean direction.  As a result, the difference of the fuel properties (the heavy property of fuel) can be detected as the change of the air-fuel ratio of the exhaust gas, and the fuel properties can be accurately determined on the basis of the output of the air-fuel sensor or a control parameter changing in conjunction with the output.
