Filed: 1986-06-14
Abstract: PURPOSE:To couple respective CRTs of red(R), green(G) and blue(B) with a lens by inserting a glass plate whose thickness is tapered into a liquid filled in the inside of a connecting metallic fixture to use a common coupling fixture. CONSTITUTION:The glass plate 11 whose thickness is changed in taper shape is inserted to the connecting metallic fixture 5.

Title: Cordless telephone set
Inventor: SEO MASAYOSHI
IPC: H04M1/00
Filed: 1995-06-06
Abstract: PURPOSE: To enhance the utilizing efficiency of a telephone line by sending a control signal to set a slave set in the standby mode when a master set detects a prescribed signal for a prescribed time while the slave set is set to the speech mode. CONSTITUTION: While a slave set detects non-application of a charging voltage and set in the speech mode, a master set uses a mute circuit 9 to mute a reception signal of a reception section 4 when a key operation input of the slave set is not detected for a prescribed time or over thereby preventing transmission of a voice signal to a telephone line 1 via a line interface 2. After the operation of voice mute or when the key entry detection time is within a prescribed time, a control section 10 sends a forced speech termination control signal to the slave set and opens the telephone line 1 when a busy tone detection circuit 7 detects a busy tone. On the other hand, the slave set receives the forced control signal and is placed on a charger, the slave set sends a control signal of line interruption and set to the standby mode.

Title: Recording apparatus
Inventor: KITAMURA TETSUYA
IPC: B41J2/385
Filed: 1992-05-29
Abstract: PURPOSE:To provide a compact recording apparatus capable of simply holding an aperture electrode while applying tension to the electrode without using a tension applying means such as a spring. CONSTITUTION:A vibrator 42 is largely expanded as compared with an aperture electrode by the difference of the coefficient of thermal expansion between the electrode and the vibrator as shown by (b). The width of a slit 41 becomes small apparently and an adhesive 50 is cured to strongly bond the aperture electrode 20 and the vibrator 42. Thereafter, the aperture electrode 20 and the vibrator 42 bonded each other are cooled to room temp. to complete a bonding process. By this cooling, the vibrator 42 is largely contracted as compared with the aperture electrode 20 as shown by (c) and tension is applied to the aperture electrode 20 at the part of the slit 41.

Title: Scale for measuring length
Inventor: KABAYA YOSHIHIKO
IPC: G01D5/347
Filed: 1987-06-02
Abstract: PURPOSE:To enable highly accurate measurement, by directly detecting the temperature of a scale itself for measuring length with a scale for detecting displacement formed thereon to compensate measuring errors for temperature changes. CONSTITUTION:Temperature sensors 131-133 are so shaped to have a thermosensitive section which zigzags at the right angle to the length of a scale base material 11 with a fine width and at each fixed pitch and terminal sections formed in a rectangle respectively at both ends thereof. The thermosensitive section is so formed in such dimensions that a resistance value thereof reaches a preset value. Thus, for example, when calibration, actual measurement or the like is performed, resistance values of the temperature sensors 131-133 are measured, for example, with bridge circuits 311-313 or the like and actual temperature at portions of the scale base material 11 is measured. If so, measured values can be corrected by performing a computation 35 based on the resulting detection temperature and a linear expansion coefficient of the scale base material 11. Thus, measuring errors are compensated for temperature changes thereby enabling highly accurate measurement.

Abstract: PURPOSE:To efficiently produce a Ti or Ti alloy sintered compact free from contamination by placing a Ti or Ti alloy materials to be sintered together with a large amount of a getter metal in a sintering case of a high melting point and sintering the material under vacuum or in an inert gas atmosphere. CONSTITUTION:The sample 3 consisting of a Ti or Ti alloy powder is placed on the bottom plate 2 in the sintering case 1 which is made of metal or ceramics having >=1100KTm/2, wherein Tm is the melting point (K). The sample 3 is preferably obtained by kneading Ti or Ti alloy powder and an organic binder, then injection-molding the kneaded material into moldings and thereafter partly or completely removing the binder from the moldings. Further, the getter metal 4 of an amount of >=1/2 weight of the sample 3 is placed in the case 1 together with the sample 3. As the getter metal 4, at least one metal or alloy selected from Ti, Zr, Ti alloy and Zr alloy is preferred. Then the sample 3 is sintered at about 1250 deg.C, under vacuum of <=0.01Torr or in an inert gas atmosphere. Thus the contamination of the sintered body with oxygen, etc., is prevented from occurring and also the sintering case can be used repeatedly.

Title: Ultrasonic flaw detector
Inventor: ARAKAWA TAKAHIRO
IPC: G01N29/04
Filed: 1988-06-08
Abstract: PURPOSE:To perform a stable measurement for a long time by arranging a structure of generating a surface wave using reflection within a wedge body to increase a junction strength with a test object. CONSTITUTION:A surface is formed in a metal wedge body to approach the surface of a test object as opposed thereto and a reflecting surface is formed as crossing the surface thereof at an angle of alpha+beta. Moreover, a vibrator is mounted so that a longitudinal ultrasonic wave is incident from a direction at an angle of alpha to the reflecting surface at the intersection of both the surfaces to ensure that alpha and beta satisfy a requirement of a formula (wherein CS represents a transverse wave sound velocity in the wedge body and CL a longitudinal wave sound velocity). As this apparatus is so arranged to generate a surface wave by reflection in the wedge body, a metal allowed to deposit metal on the test object can be selected as desired as material of the wedge body. In other words, stainless steel or the like is used as material of the wedge body thereby permitting the mounting of an ultrasonic flaw detector on the test object firmly by welding or the like.

Title: Cordless telephone system
Inventor: WATANABE KAZUNARI
IPC: H04B7/26
Filed: 1995-05-15
Abstract: PURPOSE: To provide a cordless telephone system which can prevent the interference of radio waves that is caused between connection devices. CONSTITUTION: A slave unit that is used as an extension telephone of a cordless telephone system and a connection device are provided with the attenuator circuits 302 and 402 respectively. These circuits 302 and 402 control the transmission levels of radio waves. The intensity of the radio wave received from the slave unit is recognized by a CPU 308 of the connection device based on the output value of an S meter, and the CPU 308 estimates the distance between its connection device and the slave unit. Then the operations of the connection device and the circuits 302 and 402 are controlled based on the estimated distance. Thus the output of the radio wave to be transmitted is reduced when the distance is small between the slave unit and the connection device, so that the output of the radio wave never affects the periphery.  At the same time, the sensitivity of both slave unit and connection device are weakened, so that they are not easily affected.

Title: Flow controller for flow-through blower

IPC: F04D17/04
Filed: 1981-09-04
Abstract: PURPOSE:To vary flow rate without degradation of the drive motor efficiency by providing a heater extended in the direction of the shaft axis of a flow- through impeller on a rear guider. CONSTITUTION:As the flow-through impeller 2 is driven at a constant number of revolutions n with the heater 8 activated by turning on the control switch, upward air current is produced as indicated by the arrow C near the heater 8 as the heater 8 warms up. Therefore, fluid becomes hard to flow through the impeller 2 near the heater 8 so that the fluid flow B1 alters to the fluid flow D1 and the flow B2 also alters to the flow D2 after the flow D1. Therefore, an absolute value of the maximum value in the efficiency 7-flow rate Q characteristic under the heater 8 activated remains almost the same but shifting of the peak point.
