IPC: G01L9/00
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To measure the intensity of an ultrasonic vibration at constant accuracy without requiring highly accurate positioning of the end face at a sensing part in the advancing direction of the ultrasonic vibration, by providing a means for transducing a sound pressure propagating on a rod-like body into an electric signal at the base end part of the rod-like body provided with a spherical sensing part at the forward end part thereof. SOLUTION: A hollow or solid rod-like body 21 made of transparent resin or glass has a hemispherical surface 22a at the forward end thereof. The hemispherical surface 22a serves as a sensing part 22 and the rod-like body 21 is set while directing the sensing part 22 toward cleaning liquid ejected from a nozzle port. The rod-like body 21 has a cone-like gradually enlarged part 23 at the base end thereof and a piezoelectric element 24 for transducing vibration into electric signal is bonded to the end face at the enlarged 23. The rod- like body 21 is provided, in the way thereof, with a tubular damper member 28 made of a resilient material. The damper member 28 prevents the sensing part 22 from resonating to an ultrasonic vibration imparted to the cleaning liquid.

Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To ensure electrical continuity between an electroformed blade and a flange to reliably carry out the setup of the blade and to prevent the blade, a spindle and the like from being broken by a method, wherein plated layers are respectively formed on the parts to be pinched by the flange of the electroformed blade to a degree such that projected abrasive grains are buried in the plated layers. SOLUTION: Abrasive grains 11 consisting of a diamond or the like are projected from the surface of an electroformed blade 10 and moreover, plated layers 12, such as nickel-plated layers, having conductivity are formed in such a way that the abrasive grains 11 are buried in the layers 12. These plated layers 12 are respectively formed on parts 13 by being pinched by flanges, which come into contact with the fixed flanges 32, and are constituted of an electroless plating layer of a thickness less than 5 μm, for example.  In such a way, from the fact that the layers 12 are so formed that the abrasive grains 11 are buried in the layers 12, an electrical signal, which is made to flow when the blade 10 comes into contact with the metal part of a chuck tape at the time of the setup of the blade, is reliably transmitted to the flange 32 through the parts 13 to be pinched by the flange, which are formed with the plated layers 12.

Title: Phase locked circuit
Inventor: NAKAMURA NORIO
IPC: H03L7/08
Filed: 1983-12-21
Abstract: PURPOSE:To attain highly accurate phase locking with simple constitution by adding a voltage limiter at the next stage of an LPF of a phase locked circuit which is used when a digital signal modulated by a self-clock system is demodulated. CONSTITUTION:An input pulse signal 26 and an output signal 31 of a voltage control oscillator VCO25 are supplied to a phase comparator 21 for comparison of phases. Then a signal 27 having the pulse width which advances the phase in response to the phase difference obtained from the comparison is delivered to a charge pump 22 together with a signal 28 having the pulase width which delays the phase according to said phase difference. The pump 22 converts the signal 27 or 28 into an analog quantity of voltage or current and supplies it to an LPF23. The LPF23 supplies its output voltage 29 to a limiter 24, and the limiter 24 decides the upper limit value of the voltage 29 and delivers it to the VCO25. Then the VCO25 varies the frequency in response to the input voltage and then produces a frequency near the frequency that secures synchronization since the range of input voltage is limited. Thus the synchronization is secured with a correct frequency.

Title: Memory backup circuit
Inventor: YOSHIDA HISASHI
IPC: H02J9/06
Filed: 1987-09-24
Abstract: PURPOSE:To decrease the number of parts and also to reduce the areas occupied by the parts and the power consumption by connecting the output of a voltage detecting circuit to an enable terminal of a line decoder so that the output of the line decoder can perform the address decoding and backup control operations. CONSTITUTION:The output of a voltage detecting circuit 3 is supplied to the enable terminals G of line decoders 7-1-7-N. These decoders 7-1-7-N are activated when the voltage of a system power supply 1 is normal and then inactivated when the voltage of the power supply 1 drops. Then the memories 5-1-5-n are all inactivated owing to the inactive states of the decoders 7-1-7-N. Thus these line decoders double as address decoders and backup controllers and therefore the outputs of the decoders can be connected to the enable terminals CE of memories 5-1-5-n. Then the number of parts can be decreased together with reduction of the areas occupied by these parts as well as the power consumption.

Title: Fluid bearing
Inventor: MIYASAKA TAKANORI
IPC: C10M105/34
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To obtain a fluid bearing having a low temperature dependency of a bearing torque and suppressed evaporation loss even after a long service by packing a monoester-based lubricating fluid into the gap of a fluid bearing. SOLUTION: The monoester oil based oil (M-816 or M-816+DOS) used as a base oil for a fluid bearing has a high viscosity index and a low viscosity, so that it can provide a low bearing torque over a wide temperature range and has reduced tendency toward spattering even when the fluid bearing is rotated at a high speed. It is desirable that the monoester is used in combination with other esters such as dioctyl sebacate(DOS) having a cloud point of 0 deg.C or below, for it has a limited service temperature range because of its lowered fluidity at a low temperature. The monoester based fluid shows low evaporation loss with the lapse of time and is excellent in totality as a lubricating fluid for the fluid bearing of a spindle motor.

Abstract: PURPOSE:To detect in any case correctly the temperature on the outer bottom face of a cooking vessel with a temperature sensor and heat shielding cylinder, etc. being cooled by sending cooling air into a heat shielding cylinder which shields heat for a temperature sensor. CONSTITUTION:A temperature sensor 2 installed on a central opening 3a of a burner cap 12 detects temperature of the outer bottom face of a cooking vessel 1 which is mounted on a kettle holder, and signals from the temperature sensor 2 are transmitted to an electric circuit in order to regulate the amount of gas jetted out from a nozzle 9 for controlling the caloric force or stopping combustion. Further, since a heat shielding cylinder 4 which protects the temperature sensor 2 and shields heat for it communicates with a blower fan 13 via a blase cylinder 11, secondary air partly for cooling cools the temperature sensor 2 and the heat shielding cylinder 11 and hits the bottom of the cooking vessel 1, then goes to its periphery to become the secondary combustion air for flame A, preventing additionally the heat effect from the flame A of a gas burner 3, and allows the outer bottom face of the cooking vessel 1.
