Title: Distance measuring instrument
Inventor: ARIGA YUICHI
IPC: G01C3/06
Filed: 1995-02-06
Abstract: PURPOSE: To make it possible to measure the distance accurately without adding a change to a control circuit even for an medium distance by performing infinity judgment in correspondence with the output level of an integration means after the elapse of a constant infinity judging time from the starting time of inverse integration. CONSTITUTION: The spot projected from an infrared-ray emitting element 2 is reflected from an object 7 and returned to a position detecting element PSD) 1. At this time, the distance to the object 7 is found based on a part of the PSD 1 at which the image of the spot is focused. That is to say, when the object 7 is near, the image is focused at Near of the PSD 1. When the object 7 is far, the image is focused at Far. Two signal outputs F and N of the PSD 1 is integrated by the difference signal (F-N) for a specified time. Then, the result undergoes inverse integration by the sum signal (F+N), and the inverse integration time until the returning to the reference voltage is obtained in a timer circuit 5.  In a microcomputer 6, an infinity judging means performs the infinity judgment in correspondence with the output level of the integrating means after the elapse of the constant infinity judging time from the starting time of the inverse integration. This is performed by the programming of the microcomputer 6.

Title: Foaming mold
Inventor: SAITO SHINJI
IPC: B60R21/04
Filed: 1985-02-04
Abstract: PURPOSE:To enable to remove the building-up of air around the groove part of a foamed product and consequently cracks at the fillet of the bottom of the groove by a structure wherein at least the upper end portion of a weir part is made gradually thinner upward. CONSTITUTION:At a weir part 9, the protrusion height of which is 30mm or more, at least its upper end portion is made gradually thinner upward. Because the thin-walled part made at the upper end portion of the weir part 9 allows to flow foam smoothly, when the foamed raw material poured in both sides or one side of the weir part 9 flows in foamed manner to the opposite side of the weir, no stagnation of a large amount of foam develops around the weir part. Accordingly, gas causes no building-up of air in a foamed product. In addition, because the provision of thin-walled part at the upper end portion of the weir part eliminates edgy corners at the crest of the weir and building-up of air in the foamed product, the strength of the product is enhanced, resulting in sufficiently effectively preventing cracks in the foamed product due to stress concentration from developing.
