Inventor: SATOU TAKANORI
IPC: G01L5/00
Filed: 1982-04-10
Abstract: PURPOSE:To surely measure a local strain in a descending range, by measuring the relation of the position of a concave point obtained by copying a convex point which is stuck on the surface of concrete, etc. on a transfer plate. CONSTITUTION:Plural marked points are determined on the surface of a test piece 1 of concrete and a steel ball (2) is stuck on said point via a square iron piece 3. A transfer plate 4 made of lead, etc. is press-stuck on the surface of the piece 1 stuck with a convex point 2 and a concave point is copied on the plate 4. A local strain in a descending range is accurately measured by measuring the relation of the position of the concave point on the plate 4 by a contact strain gauge preliminarily attached with the same steel ball as a convex chip 5.

Title: Air conditioner
Inventor: NOGUCHI HIROSHI
IPC: F25B41/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To realize a piping system which reduces the number of parts by shortening the total length of piping of an outdoor unit and room units in a multiple air conditioning system in which a refrigerant is circulated through the plurality of room units by a distribution refrigerant pipe from one outdoor unit. SOLUTION: A refrigerant divider 10 is so arranged to get a refrigerant further branched off optional distribution refrigerant tubes 5a-5c divided into several systems from an door unit 3 and several room units 1a-1c can be connected ahead thereof. The refrigerant divider is arranged at a selected location indoors at a distance taken as far as possible from the outdoor unit and at an equal distance from the room units to be connected thereto. This reduces the set of the outdoor unit and the piping to one and cuts the total length of the piping. Thus, a simple execution of work and a lowered effect of pressure loss are possible, thereby producing an air conditioning system with a higher operation efficiency.

Title: Method for controlling communication
Inventor: MARUYAMA AKIRA
IPC: H04Q9/00
Filed: 1985-03-27
Abstract: PURPOSE:To relieve the load of a master station by allowing a slave station not receiving a signal from a host station until an estimated time to send an inquiry signal in the slave station of a system where the inquiring signal is transferred sequentially from a master station to plural salve stations. CONSTITUTION:The master station sends an inquiry signal to a slave station 1 only via a branch device 13 and a route 2 from a route 1. The slave station 1 returns the signal to the master station when a reply signal exists, but transfers the inquiry signal to a slave station when no reply signal exists, and a slave station 4 sends a signal finally to the master station. The slave stations 2-4 monitor the inquiry signal to the slave station 1 and sets a required time of a signal transferred to the own station from the point of time to a timer. When a timer is over until the signal is transferred from a high-order station, it is regarded that the inquiry signal comes from the high-order station and the inquiry signal is sent to a low-order station. Thus, the load of the master station is relieved and the inquiry signal is prevented from being vanished even if a fault takes place in a slave station.

Title: Preventing method for occurrence of crystal defect of silicon single-crystal substrate
Inventor: KOTANI TOSHIYUKI
IPC: H01L21/22
Filed: 1978-05-22
Abstract: PURPOSE: To prevent the occurrence of a crystal defect by forming diffusion strain by diffusing atoms, different in atom radius of Si, to the circumference of the other main surface of a Si single-crystal substrate in a belt shape.  
     CONSTITUTION: On the top and reverse surfaces of a Si single-crystal substrate, oxidized films 2 and 3 are formed. In oxidized film 2 on a main surface other than a surface where a semiconductor element is to be formed, two opening parts 4 and 5 of approximately 250μm in width are concentrically formed, at an interval of approximately 50μm, approximately 4mm away inward from th external circumference. Through opening parts 4 and 5, atoms, differing in atom radius from Si, such as Sb atoms are thermally diffused to a surface density of 10 19 /cm 3  and a depth of 5μm approximately so as to form diffusion regions 6 and 7. In consequence, diffusion strain is generated in the Si substrate. Then, oxidized films 2 and 3 are removed. The substrate formed by the above method is oxidized for about thirty minutes in a vapor atmosphere of 1140°C. Consequently, a region without strip lines is expanded to a degree of 90%, so that great improvement can be realized.
