Title: Method for measuring thickness of resin laminated body
Inventor: MATSUMOTO NORIYA
IPC: G01B17/02
Filed: 1992-01-09
Abstract: PURPOSE:To quickly and accurately measure the thickness of each layer of an objective product composed of a laminated body constituted of thin resin layers having similar compositions without destroying the product. CONSTITUTION:In the title method, ultrasonic waves having a first frequency of 4-6MHz and second frequency of 10-20MHz are transmitted toward a laminated body composed of resin layers.

Title: Grinding stone
Inventor: TEZAKI MUNEAKI
IPC: B24D3/14
Filed: 1986-01-31
Abstract: PURPOSE:To suppress abrasion and secure a long service life by obtaining the abrasive grains from the unit type sintered particles containing a plurality of superhard minute particles and carrying out the sintering formation by the bonding agent such as resinoid bond, thus increasing the unevenness on the surface of the abrasive grain and increasing the abrasive grain holding force and constituting the cutting edge from the edge lines of the superhard minute particles. CONSTITUTION:An abrasive grain 1 is made of the unit type sintered body particle containing a plurality of superhard minute particles which are obtained by pulverizing the sintered body of the superhard minute particles 2 made of diamond, wurtzite type boron nitride, cubic system boron nitride, etc., having the ceramics such as TiC, TiN, and Al2O3 as bonding agent 3. The sintering formation with the bonding agent 4 such as resinoid bond and vitrified bond is carried out to obtain a grinding stone. Since the abrasive grain 1 is constituted in unit form from a plurality of superhard minute particles 2, the shape of the surface of the abrasive grain 1 is rich in unevenness, and the abrasive grain holding force is improved. Further, a metal covering layer does not exist, and the cutting edge of the abrasive grain 1 is constituted of the edge line parts of the superhard minute particle 2 itself, and the abrasion of the cutting edge is suppressed, and the long service life can be secured.

Title: Flame-retardant vinyl chloride resin composition
Inventor: HAYASHI MASAYUKI
IPC: C08K5/3492
Filed: 1995-02-08
Abstract: PURPOSE: To obtain a flame-retardant resin composition having excellent flame retardancy, good processability and excellent mechanical properties and being safe from the viewpoint of industria hygienics. CONSTITUTION: This flame-retardant vinyl chloride resin composition is obtained by adding a trihydrazinotriazine blowing agent, calcium carbonate and optionally other additives to a vinyl chloride resin as a base polymer. When this composition is burnt, the trihydrazinotriazine blowing agent is decomposed to form a nitrogen gas, the formed nitrogen gas reduces the oxygen concentration near the site of burning, and a film made of the base polymer covers and insulate the site of burning. The ammonia gas formed simultaneously with the formation of the nitrogen gas is adsorbed by the calcium chloride formed by a reaction of the calcium carbonate with the base polymer.

Title: Power supply device
Inventor: SHOJI TAKASHI
IPC: H02M3/00
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To enable an output voltage to be outputted by resetting a latch circuit during a specific period when the output voltage of a power supply circuit for control circuit reaches the starting voltage of a start/stop control circuit and hence preventing the latch circuit from malfunctioning when a DC input voltage rapidly changes. SOLUTION: A reset from a reset circuit 9 is outputted immediately before reaching the operation start voltage of a start/stop control circuit 4. The latching of a latch circuit 8 is canceled by the reset, thus resulting in an initial state. More specifically, when a DC input voltage Vin momentarily stops and a DC output voltage Vcc, to the start/stop control circuit 4-drops and reaches an operation stop voltage and then the start/stop control circuit 4 stops the operation of a conversion control circuit 2, a reset for canceling latching is inputted from the reset circuit 9 to the latch circuit 8 immediately before the Dc output voltage Vcc reaches an operation start voltage, thus resulting in an initial state. As a result, the DC input voltage Vin is thrown again, thus enabling an output voltage to be outputted.

Title: Small-sized metal vapor discharge lamp
Inventor: HONDA KAZUO
IPC: H01J61/073
Filed: 1989-01-31
Abstract: PURPOSE:To prevent reduced light flux retaining rate and starting capability by establishing certain relationships between the length of a bent tip portion of an electrode stem, the length of an electrode coil and the diameter of coil component wire. CONSTITUTION:Assuming that L1 is the length of a bent tip portion 8a of an electrode stem 8, L2 the length of an electromagnetic coil, and d the diameter of coil component wire, d<=L1<=3d and d/2<=L2-L1<=3d are established between them. Since d/2<=L2-L1, the belt tip portion of the electrode stem is at least d/2 back from a discharge space side compared to the tip of an electrode coil portion 9. This prevents arc spot from occurring at the tip portion of the electrode stem which has low melting point, thereby preventing reduced light flux retaining rate due to blackened tube wall. Further, since L1<=L3, the size of the electrode coil portion 9 is limited, avoiding the electrode coil portion becoming too large, hence prevention of reduced starting capability. Further, the electrode stem 8 is either made of pure rhenium metal or rhenium-tungsten alloy or has its surface covered with a specific material.
