Title: Metallic golf club head and its production
Inventor: OYAMA YASUO
IPC: A63B102/32
Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To make inertia moment larger. SOLUTION: A head body 12 consists of a titanium alloy and an opening 16 is formed in a sole part 14. A sole plate 18 covering the opening 16 is formed by welding to the sole part 14 of the head body 12. The sole plate 18 is formed of a clad plate comprising a base material plate 20 consisting of a titanium alloy and a brass plate 22 having the specific gravity larger than the specific gravity of the base material plate 20 joined to its surface. The peripheral edge of the base material plate 20 is formed as a flange part 24 bent to a front surface side by as much as the thickness of the brass plate 22.

Title: Leak preventing structure for weld joint part of tube
Inventor: OSAKI TOSHIO
IPC: F28F11/02
Filed: 1990-06-29
Abstract: PURPOSE:To prevent leak of fluid inside a tube securely and secure the reliability by using a protective short tube manufactured of one-directional share memory alloy, or applying a tension seal to close parts to a weld joint part of a tube and a protective short tube by circular heat diameter shrinkage or diameter expansion work. CONSTITUTION:Shape memory alloy having a one-directional shape memory performance is moulded and manufactured under a room temperature, and the shape is memorized at the transformation point to be a thin protective short tube 5 which is engaged around the outer circumferential surface of a weld joint part 4 of a heat transmission tube 1. When the protective short tube 5 gets over 200 deg.C to return to the memorized share, it is tightly applied to the outer circumferential surface of the weld joint part 4 to seal the part, and leak can be prevented securely. Or otherwise, a protective short tube 7 is engaged around the weld joint part 4 of the heat transmission tube 1, so the heat transmission tube 1 close to the weld joint part 4, a joint tube 3, and the protective short tube 7 are tension sealed by circular heat diameter shrinkage method. The protective short tube 7 is thus tension sealed by circular heat diameter shrinkage, thereby leak can be prevented.

Title: Navigation system
Inventor: JINNO MASARU
IPC: G01C21/00
Filed: 1994-07-26
Abstract: PURPOSE:To improve the accuracy in navigation and improve ease of operation in a navigation system using a map book. CONSTITUTION:At the time when route information is inputted, the coordinates of each passing point, i.e., the latitude and longitude thereof, are inputted by using a map book 1 and a touch panel 2 and the information thereon is stored in an IC card 5 through an IC card writer 3. In the case where a voice information is needed on the occasion, the voice information is inputted simultaneously through a microphone 4 for inputting voice. The IC card 5 thus prepared is held in a main-body apparatus 6 of a navigation system. At the time of running, the navigation system determines whether the current position of a vehicle coincides with each passing point stored in the IC card 5, and when they coincide with each other, it outputs a corresponding voice message from a speaker 62 for a voice guide.

Title: Low frequency electro-acoustic transducing method
Inventor: TAKASAKI HAIMI
IPC: H04R15/00
Filed: 1981-10-29
Abstract: PURPOSE:To transmit and receive low frequencies easily with a transmitter/receiver of  small size for high frequency, by using a magnetostriction oscillating element having a  specific magnetostriction characteristic, superimposing or modulating an electric signal  in high frequency in comparison with a transmitted or received low frequency sound  wave to impress the signal to the magnetostriction element. CONSTITUTION:An OSCL is a low frequency oscillator generating a transmission signal,  an OSCH is a high frequency oscillator generating a half of the resonance frequency of  a transmitter XT comprising the magnetostriction oscillator, and an M is an amplitude modulator of said both signals. In taking the waveform of both the signals as Figs. (a),  (b), an output of the M has a voltage waveform as shown in Fig. B-c and applied to  the XT. The transmitter XT has a negative magnetostriction to contract to the intensity  of both positive and negative magnetic fields H. In applying a voltage as shown in  Fig. (c) to a coil 2, the intensity of the alternate magnetic field of the oscillator is rectified so as to be contracted as shown in Fig. F and the oscillation has a low frequency  component the same frequency as the OSCL as shown in broken lines 5 and double high frequency components of the OSCH. Thus, the high frequency component irradiated  in water transfer is attenuated quickly, but the low frequency component is less attenuated to reach further.

Title: Fiber injuring insect controlling agent
Inventor: AIKAWA TEIICHI
IPC: A01N35/06
Filed: 1985-08-07
Abstract: PURPOSE:The titled excellent controlling agent, containing combination of an alkyl p-hydroxybenzoate and camphor, capable of exhibiting feeding inhibitory action on fiber injuring insects, having high long action property and low toxicity without liquefying even on allowing to stand nor deteriorating plastic products. CONSTITUTION:A fiber injuring insect controlling agent is prepared containing combination of an alkyl p-hydroxybenzoate and camphor as an active constituent. Preferably, the alkyl p-hydroxybenzoate is methyl, ethyl and n-propyl ester thereof. The optimum mixing ratio of the alkyl p-hydroxybenzoate to the camphor is normally selected from 2-50wt% range. Since the vapor pressure of the alkyl p-hydroxybenzoate is lower than that of camphor and the content of the former in the composition ratio of both tends to increase with time, the above-mentioned mixing ratio is preferred.

Title: Smoke sensor and smoke sensing system
Inventor: WATANABE JUNICHI
IPC: G01N21/53
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To detect a smoldering fire at an early stage and to improve reliability by determining a fire and issuing an alarm in the case the integrated value of smoke density for a predetermined period of time exceeds a predetermined value while smoke density is gradually increases. SOLUTION: When smoke is produced, for example, by a smoldering fire and a photodetector 3 detects a minute current, the detected minute current is amplified at a computation processing unit 4 and converted into a digital signal. The determining part 5a of a determining part 5 determines whether the signal exceeds the first threshold value A or not, and issues an alarm in the case it exceeds the threshold A. If it does not exceeds the threshold A, a determining part 5b determines whether smoke density has been gradually increased or not. If it is increased, a determining part 5c starts the computation of the integrated value of smoke density and issues an alarm when the integrated value exceeds a threshold X.

Abstract: PURPOSE:To control reversible rotation a DC motor and also to enable reducing a development time and cost and having a controller for common use by applying a predetermined voltage through a resistance type potential divider, etc., in place of a position-transducing magneto-effect element to be used in a brushless motor and by changing this voltage. CONSTITUTION:The u(-)-, v(-)-and w(-)-terminals of an apparatus are divided in potential by resistances 3, 4 to be constantly biased to about 1/2Vcc. The u(+)-terminal is set to a voltage higher than 1/2Vcc by resistances 2, 1. Then, when Q1 is ON, R3 is in parallel with R6 and at a voltage lower than 1/2Vcc. This is a state where SW1 is on the a-side, i.e., Q1 is OFF and when SW1 is on the b-side, Q1 is ON. The voltages of the v(+)-and w(+)-terminals are determined in like manner and can be changed by SW1. Therefore, the control of reversible rotation of DCM is made possible by change-over of SW1.

IPC: H01M8/22
Filed: 1984-08-22
Abstract: PURPOSE:To make a noble metal catalyst unnecessary and eliminate the danger of explosion by introducing FeCl3 to the cathode to produce FeCl and HCl thereby performing electric power generation and oxidizing the thus produced FeCl2 solution containing HCl to regenerate FeCl3. CONSTITUTION:Hydrogen gas is introduced to the anode and an aqueous FeCl3 solution is introduced to the cathode. FeCl2 and HCl are produced in the cathode to perform intended electric power genetration. Air or oxygen is sent into an aqueous FeCl2 solution containing HCl produced in this process to oxidize Fe<2+> into Fe<3+> thereby regenerating FeCl3. With this fuel cell structure, the voltage decrease of the cathode is minimized and almost constant container voltage can be produced. Since only a little thermal energy is produced by voltage decrease, it is not necessary to provide this fuel cell with a cooling device.
