Title: Optical tomograph
Inventor: SUGIYAMA YUICHI
IPC: G02B21/18
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To rapidly scan a sample in the depth direction by providing a periodic optical path length variable mechanism by a transparent rotating body on each optical path of an object light and a reference light. SOLUTION: A light beam emitted from light sources 1, 1 and having a specified coherence length is split into two by beam splitters 1, 3, and one light (the reference light) reaches reference mirrors 1, 5 through periodic optical path variable mechanisms 1, 4 by a transparent rotating body. The light reflected by the reference mirrors 1, 5 is returned to the beam splitters 1, 3 through the periodic optical path variable mechanisms 1, 4, and a part thereof is returned to light reception parts 1, 2. The frequency of the reference light is transited in passing the periodic optical path variable mechanisms 1, 4.  The other light (the object light) split by the beam splitters 1, 3 also reaches objective mirrors 1, 7 through period optical path variable mechanisms 1, 6, and is reflected and returned to the light reception parts 1, 2 through the periodic optical path variable mechanisms 1, 6 and the beam splitters 1, 3. The interference light formed by superposing the object light whose frequency is transited on the reference light whose frequency is transited is processed by a computer to form a tomographic image.

Title: Pavement material of high durability
Inventor: ASAI KATSUTOSHI
IPC: E01C7/30
Filed: 1990-04-02
Abstract: PURPOSE:To prevent a pavement material from being softened with heat to improve its durability by laying a mixture in which a binder mainly made of nonsaturable polyester is mixed in slug of aggregate crushed with water at a specified ratio. CONSTITUTION:A mixture obtained by mixing a binder made of four liquids, i.e., nonsaturable polyester as its main material, low shrinking material, catalyst and accelerating material with slug crushed with water used singly for aggregate at a specified rate is layed on a surface part of asphalt concrete pavement or cement concrete pavement at the thickness of 5-10cm. At this time, the constitution ratio between unsaturable polyester, and catalyst and acceleration material is changed to control the time of hardening. The high durability pavement material has no fear of being softened with heat when it is layed, no such viscosity of asphalt concrete, and excellent apparent density, stability and mechanical strength. It is thus possible to have an excellent applicability substantially as the same as asphalt concrete pavement and durability such as of cement concrete pavement.

Title: Posture changing mechanism for paper sheet
Inventor: NAKANO TAKAO
IPC: B65H9/16
Filed: 1986-04-16
Abstract: PURPOSE:To perform smooth and normal posture change without bending and without change in speed in the conveying direction when a sheet of paper is translocated from a first conveying passage by forming a posture changing mechanism with plural belt trains or roller trains and plural driven rotary bodies. CONSTITUTION:A sheet of paper 5 which has been conveyend on a first conveying passage 1 at a velocity V is fed being interposed in between plural belt trains 3a-3c and plural driven rotary bodies 4a-4n, and delivered to a second conveying passage 2. In this case, a turning force is applied to the sheet of paper 5 due to difference in speeds among the belt trains 3a-3c, finally delivering the paper 5 to the second conveying passage 2 in the posture of the paper 5' which is 90 deg. rotated from the posture of the paper 5 on the first conveying passage 1 and, after that, the paper 5 is conveyed in this posture at the velocity V. Since the speed in the conveying direction when the sheet of paper 5 is translocated is not fundamentally varied unlike the conventional case where a sheet of paper is rotated at a speed zero, even an object such as a piece of mail having a lopsided content can undergo smooth and normal posture change without being bent.

Abstract: PURPOSE:To enable an interelectrode-relative position to be precisely kept, by using a conical body made of melted conductor molded in said conical shape by means of the attractional force of the field as the tip part of at least one electrode. CONSTITUTION:Inside a container part 3 fixed to a vacuum tank 1, for instance, such a conductor as metallic aluminum is filled to form the tip part 21 of an electrode base part 2; and around the container part 3, for instance such a heating source 7 as a resistance wire heater is installed in order to melt the conductor 22. The melted conductor 22 flows down through a slender hole part 23 present inside an electrode base part 2 due to gravitational force, and forms the conical tip part 21 at the tip of the electrode base part 2. After the tip part 21 is formed, heating by the heating source 7 is stopped by turning off a heater power supply 8. Consequently, every time the electrode is consumed, it can be recovered to the initial condition by simple operation so that repetition of its discharge becomes possible under a certain condition for a long period of time.

Moreover, a foot space is arranged at a front door part is a lecturer side so as to improve the operability of the lecturer. Thus, the feet and the knees of the lecturer are not brought into contact with the front door part in the configuration.
